What should be the behavior of Background with shfil

forums_noreply@adobe.com — Thu, 13 Nov 2014 16:37:58 GMT

I have a simple PostScript file that uses a Radial shading dictionary and shfill operator.

When i drag this PostScript file in Adobe Distiller 11, it generates a PDF file contains the Background entry in the shading dictionary.

As per PLRM, shfill operator must ignore the Background entry if present.

is it correct?

Axial shading pattern with different alpha

forums_noreply@adobe.com — Thu, 13 Nov 2014 07:34:45 GMT

Hi,

I'm trying to apply different alpha values to axial shading pattern when drawing and I've found PDF Axial Shading Pattern ranging opacity very helpful.

But what kind of soft mask (PDF 1.4) should I use (dictionary or image mask)? And how could I create that mask?

I wrote some pdf code based on my limited understanding of pdf 1.4 reference and that doesn't work.

CIDFont and PDF

forums_noreply@adobe.com — Tue, 11 Nov 2014 14:55:39 GMT

Hi,

thanks to the lrosenth for the help with my question about support for CID keyed Type1 fonts in PDF.

I will make sure that I read the ISO PDF spec - it is more clear.

Sadly, I have another question:

I have a valid CIDFont (consists of a readable PS part and also binary data which I believe is _parts_ of a CFF font program, not the whole program).

The readable PS part has info like byte offsets to CharStrings and also the table that maps CID values to font/glyph (CIDMap)

The FreeType library will render glyphs from this font.

The binary parts appear to be the CIDMap and CharStrings etc - but not the usual CFF header stuff - ie. just the bits you need.

My question: Am I right that you cant put such a CIDFont in a PDF file as an embedded font program (as part of a composite CIDFontType0) ?

From my reading of the spec, a composite font (Type0) in PDF references a CIDFont dict that doesn't have any of the info that the PS CIDFont contains (such as byte offsets to charstring data etc)

and so it needs the complete CFF program - specified as /FontFile3 in the font descriptor.

regards

JLM

PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 20:28:33 GMT

Hi,

I understand that PDF supports embedded CFF font programs for composite fonts of type CIDFontType0 - the spec is clear.

But, does it support embedded font programs that are not CFF - ie. CIDFont with type 1 descendent for example?

The spec only mentions CFF when talking about type 1 composite fonts, but it isn't totally clear.

So, does PDF support embedded non-CFF programs for composite type 1 fonts?

Changing creation date on adobe acrobat 9

forums_noreply@adobe.com — Thu, 06 Nov 2014 09:20:20 GMT

I've got a folder full of old PDF files at work. They are all labeled DD-MM-YY to signify the date they were made but the pdf's were originally in Word format and when they were all converted to PDF's, they all took that day as their created date. I'm looking for a way to change the created date on these hundreds of PDF's to match the date in the file name. Is there an easy way to do this? I have to print the documents and organize them chronologically by date. However, I need to also have corresponding creation dates with the documents. I'm not good with scripting or programming however I am great at following step by step directions. I would greatly appreciate help on this since this is a semi time sensitive project.

Thank you.

Form XObjects without Resources - do we ignore ancestor forms?

forums_noreply@adobe.com — Sat, 25 Oct 2014 07:47:10 GMT

Hi, I'm just wondering what happens in the below situation.

We have a Page which includes a form XObject #1, which itself contains another form XObject #2.
Form #2 uses a font but has no Resources dictionary. The font is defined against the Resources dictionary of form #1 instead.

Based on the PDF spec (which I've copied below) a client application should refer to the original Page object to see if the font is defined there but should not check form #1. We should therefore get a missing font error as the PDF is invalid. Is this correct?

For reference the PDF spec v1.4 says the below.

"A form XObject or a Type 3 font’s glyph description may omit the Resources entry, in which case resources will be looked up in the Resources entry of the page on which the form or font is used. This practice is not recommended."

Is a zero length glyf table valid for a TTF subset?

forums_noreply@adobe.com — Fri, 24 Oct 2014 23:58:45 GMT

I've posted related queries in a few forums - there is some background info at https://forums.adobe.com/thread/1611899 and it was suggested I ask the experts here

Basically in some situations InDesign is generating a subset font with a zero length glyf table.

Does this 'exists but zero length' table fulfil the criteria from the PDF specification?

The following TrueType tables are always required: “head,” “hhea,” “loca,” “maxp,” “cvt_,” “prep,” “glyf,” “hmtx,” and “fpgm.”

A number of programs are not happy with such files, but Adobe products seem to handle them. However Acrobat in particular is fairly forgiving as we all know.

Microsoft's font validator says the subset is not valid. Programs like Ghostscript attempt to fix it by adding an empty table.

Note that the stream starts and ends with a newline character. There are 17 bytes and the last line ending is not part of the stream length.

The remaining bytes 16 bytes have 15 bytes of data, (the first line ending is ignored (right?)):

PDF Axial Shading Pattern ranging opacity

forums_noreply@adobe.com — Mon, 22 Sep 2014 13:48:59 GMT

Hi,

I'm trying to figure out the way to have in PDF (say 1.4) an axial shading pattern but such that the opacity of the colors ranges along the shading, not just the colors themselves.

This is naturally supported in rendering systems, such as GDI+, where the alpha channel is in the color. But in PDF, the opacity is controlled separatedly, so in the case of a shading, I have no idea where to specify that.

Please notice that my question is about PDF itself (as in the spec), regardless of any PDF generation library/software.

TIA

Adobe Reader crashes on duplicate pages

forums_noreply@adobe.com — Sat, 20 Sep 2014 12:13:33 GMT

Adobe Reader will either give Error 14, or just crash out and quit if it comes across a PDF file with duplicate pages, for example:

/Kids [9 0 R 9 0 R]

By my reading of the standard, there is no explicit prohibition of this. Other PDF readers work ok. Is this an Adobe Reader bug, or have I misunderstood the standard?

(Motivation: I'm writing a PDF squeezer which coalesces groups of identical objects into one. This reduces the size of the ISO3200 PDF specification itself by about 20% -- lots of PDF producers seem to create duplicate objects. But if Adobe Reader crashes in this case, where else might it or other readers crash when there is unexpected aliasing of objects?)

Duplicate entries in the Fields array

forums_noreply@adobe.com — Fri, 19 Sep 2014 10:18:24 GMT

I came across a (strange) pdf and after an analysis it turned out that some of the fields occur multiple times in the Fields array.

Now when looking up the spec it states:

"An array of references to the document’s root fields (those with no ancestors in the field hierarchy)."

Is that a violation of the spec (although it doesn't state that explicitly)?

So how to deal with this kind of PDFs?

Decompressing a cross reference stream with Params.

forums_noreply@adobe.com — Sat, 30 Aug 2014 04:53:19 GMT

I'm losing my mind trying to decompress this stream. I've asked everyone and am not having much luck with it. This is a cross reference stream with decode params.

I have used an external library for decompressing this and for some reason, the xref streams just cannot be decoded. I noticed that software designed to decompress pdf files such as Quick Pdf, VeryPdf etc will decompress all streams but these. So there must be something extra about the output of these that I don't understand.

A common error message would be that the stream cannot be displayed because it contains binary data. Very odd. Any clues.

Decompressing Xref Streams?

forums_noreply@adobe.com — Tue, 26 Aug 2014 15:22:47 GMT

I am having significant problems decompressing xref streams. Unfortunately the use of Params has complicated things a little.

I am using various open source libraries to do this but I just wanted to check if my understanding is right. The ISO3200 standard doesn't quiet put it in a way I can understand.

If I am returning a decompressed Xref stream to a buffer, can I output it as one long string (adhering to white space), or do I need to recognise the output another way. Such as Objects etc?

Are Xref streams and white space rules surrounding these streams the same as the rules for all other streams.

I have files written with Adobe 9 pdf printer, are the predictors in that version, relative to previous versions, different. I'm simply trying to decompress text streams and want the xref information to navigate the document.

If there is tips for decompressing these streams please add them as I could be here for the next two years trying to decompress a single

xref stream. Maybe that's the way it's supposed to be, I don't know.

Thanks

AES 256 Revision 6 (PDF 2.0) Encryption

forums_noreply@adobe.com — Sun, 03 Aug 2014 19:53:15 GMT

I am trying to implement decryption of AES 256 Revision 6 (PDF 2.0) as described in the ISO 32000-2 spec and having some success but getting some peculiar results that I cannot resolve and would appreciate some suggestions.

Using Acrobat X on a PC and encrypting using password encryption compatible with Acrobat X, I created a set of about 20 Acrobat X encrypted PDF tests. When I ran these through our implementation to decrypt as following ISO 32000-2 particularly Algorithms 2.A and 2.B most decrypted successfully and produced correct output. However a few failed either in the authentication phase or in the intermediate key computation stage, with the latter showing an error by an invalid decryption of the first stream of PDF encountered. Next I tried another set of different tests and also got a similar pass rate. Finally I took one unencrypted PDF test and chose the same security settings of compatible with Acrobat X, restrict editing, and printing, and allowed print and used the same password for 15 generated versions of this PDF test. 13 of these 15 resultant encrypted tests ran successfully with our implementation of the Revision 6 decryption algorithm. Two failed, with one failing a match on both user and owner key and the other failing computing the intermediate owner key.

In the past when we have implemented earlier Revision 5 256 AES, or even older compatibility versions it always was the case that you either had the software working or you didn’t. And the new PDF 2.0 2B algorithm with 64+ hashes and 64+ aes encryptions of data along with 16 byte mod 3 math computations leaves little room for error.

I believe that Acrobat when encrypting is choosing a random AES IV and all data including input /U /O /UE, and /OE strings differ. Even for the case described above of the same input test, same password, and same Acrobat encryption options. Thus the input into Algorithm 2-B will differ but the output should for authentication match the first 32 bytes of the O or U key or should result in a correct final result for intermediate owner or user key if the corresponding match occurred above.

However for the few exceptions that fail the above decryption it is not easy to determine what went wrong. Just about any change to the implementation of Algorithm 2.B breaks all working test cases instead of giving a clue as to what the issue is. The possible suspects are the new SHA-384 and SHA-512 and the encrypt code. We have used SHA-256 and the AES decrypt portion in earlier implementation of revision 5 and had no problems. The AES and hash code we are using is from Gladman¹. I was wondering what others are using? It looks like Acrobat X is using RSA BSAFE Crypto – C² at least for FIPS. Could Leonard or somebody else at Adobe tell me if this RSA software is also used in general with Acrobat X?

And I think that it would be very beneficial to have and publish a set of test vectors given input into algorithm 2.B along with correct intermediate results for each step. For each hash – including which method used per step show hash results, and also encryption step results, number of steps beyond 64 minimum, as well as final result. For the 80% of tests I have working I could produce this info. For those tests I cannot get working I would need help. Perhaps someone at Adobe or elsewhere who has had greater success than I have can help? I can provide input for the problematic tests either through this forum or privately at David.Lincoln@csr.com.

How to display cyrillic characters in a PDF

forums_noreply@adobe.com — Thu, 10 Jul 2014 22:01:35 GMT

I am fairly green in terms of representing text in PDF documents and need some assistance. My main question is how do I represent Cyrillic characters in PDF files.

I know the basics of how to represent text in PDF files and the PostScript commands to use. I know that bytes written to the file in the range of 0 to 255 will print correctly when using the correct encoding (we are using the WinAnsiEncoding). What I cannot seem to figure out is how to represent extended character sets and different glyphs (such as those used in the Cyrillic alphabet) in a PDF file. Do I need to use CID fonts and CMaps?

Here is an example of the text I understand how to print:

stream

0.00000000 0.00000000 0.00000000 RG

0.00000000 0.00000000 0.00000000 rg

/Helvetica 14 Tf

7.2 768.96 Td

(Hello World!) Tj

endstream

I'm really not clear on how to represent any of the Chinese or Japanese fonts either, so really any help here is appreciated. Any examples are appreciated as well.

Thanks!

ISO 3200 - 7.5.8 Cross-Reference Streams

forums_noreply@adobe.com — Wed, 09 Jul 2014 12:13:46 GMT

I'm having trouble interpreting the Example 4 on page 48 of PDF 32000-1:2008, Specifically in relation to the blue bolded text below.

The first field of these entries is the entry type (2) ------What does the 2 represent?

number of the object stream (15) --------What does the 15 represent?

position within the sequence of objects in the object stream (0, 1, and 2)------What does this refer to?

It's just not clear what the 15 is if it's the second entry? Would somebody be able to explain where these numbers come from?

The following shows the same objects from the previous example stored in an object stream in a PDF 1.5 file, along with a cross-reference stream.

The cross-reference stream (see 7.5.8, "Cross-Reference Streams") contains entries for the fonts (objects 11 and 13) and the descriptor (object 12), which are compressed objects in an object stream. The first field of these entries is the entry type (2), the second field is the number of the object stream (15), and the third field is the position within the sequence of objects in the object stream (0, 1, and 2). The cross-reference stream also contains a type 1 entry for the object stream itself.

Best Adobe product for editing PDF, replacing English text with Thai without altering/recompressing images, graphics etc.?

forums_noreply@adobe.com — Wed, 09 Jul 2014 09:33:29 GMT

I have an English language PDF, a medical device brochure, the content of which has already been translated into Thai (in Word). I want to replace the original English in the PDF with the Thai translation easily without altering any other aspect of the brochure, like graphics, images, margins etc. (No doubt I'll have to tweak line height, font sizes and paragraph lengths a little.) I'm unsure of what would be the best Adobe product for this purpose, e.g. Illustrator, InDesign or Acrobat (or something else), that would allow me simply to open the PDF, replace the English with Thai in an attractive Thai font (to be embedded), make minor layout tweaks, then save without any compression so the quality and colours of the original photos, artwork, and graphical elements are preserved. I've heard Office 2013 allows direct editing of a PDF but I'm not sure if it converts, alters or compresses PDF graphics in some way when first opening the file. Could anyone with relevant experience please advise? Thanks in advance.

How to do multi-stage blending

forums_noreply@adobe.com — Fri, 20 Jun 2014 14:01:56 GMT

I want to do the following blending operation in RGB space:

Within the transparency group (I'm using a Form XObject), the resulting colour is the source colour (i.e. no blending). The resulting alpha is the source alpha.

Then I want to blend this form with the page using the standard transparency formula: C_r = (1-a_s)*C_b + a_s*C_s.

For instance, If I draw a solid black circle with alpha 1 and then two thin lines over it (one horizontal and the other vertical), both with alpha 0, I should end up with 4 quadrants. I can then place this group onto the page so that the 4 quadrants are drawn in black on the page and the space where the lines were drawn are transparent, so that the original page contents can be seen through it.

Is this possible in PDF, or do I need to combine the objects into a complex polygon? In my application, alpha is always 0 or 1. Section 7.2.6 of PDF version 1.5, fourth edition, seem to suggest that this is not possible (due to the Union function used to calculate the resulting alpha).

How is it that a searchable PDF text returns found words misspelled when the text is converted to an rtf file?

I can't count the hours spent correcting pdf files that appear fine, but are simply unreadable when turned into editable or searchable text. It would seem to me that once that problem is understood, a solution may be found for at least 1/2 of the misspelled words in post OCR corrections. This is a real hindrance when it come to research ... no one has unlimited time to post OCR correct files to ensure searchable texts are not overlooking important but misspelled words.

XMP updated with exiftool is not read

forums_noreply@adobe.com — Mon, 19 May 2014 17:27:49 GMT

If this question is better suited in another forum, please let me know.

The following example PDF has been used in a workflow where the XMP meta data has been updated with new values (e.g. dc:identifier has the value Metropoles).

When opening this file and looking at the meta data in for example Acrobat Pro this new updated information is not viewed but the old XMP stream is instead read by Acrobat (pdfLib).

The update looks correct as far as I can see, the object 54 has been updated and the new xref table at the end has the correct start byte for this new updated stream (byte 0022017676). So I can not understand why this new stream of XMP is not viewed in Acrobat.

Does anyone see any error in the PDF or is there any obvious reason why Acrobat wouldn't read the new XMP stream?

(other software using exiftools extract the new XMP correctly, I have also tested with some tool written in pure java and that will also show the new updated XMP as the currently working meta data)

forums_noreply@adobe.com — Mon, 19 May 2014 13:35:01 GMT

I'm looking for a technology that will help me create multiple formats of similar data from an SQL database into PDFs. I haven't found a sales rep at Adobe who knows if any of their products can do what I need and they recommended the user-to-user forums.

My web-based application will generate financial affidavits. I need a different template for each state, so I need to create these templates without getting too much into the code itself. The templates will need to draw similar data about assets, liabilities, income and expenses from my SQL database, but the data will be organized in different places on the end document depending on the state. Each state's template (some states have different formats for each county) will also have different fonts, borders, and labels, so I want to be able to create these templates easily, without getting into the code.

Do you know of any Adobe or other technology that can help me do this?

TJ operator does NOT display all glyph

forums_noreply@adobe.com — Wed, 14 May 2014 07:56:19 GMT

Hi everyone,

I have a strange behaviour when generating a PDF document by using the TJ operator:

I am using the TJ to justify multibyte glyphs.

For example this:

BT 297.640 640.940 Td /F1 10.0 Tf () Tj /F2 10.0 Tf [(Lorum) 459 (Ipsum) 459 (dolar,) 459 (etc) 459 (June) 459 (4th,)] TJ /F1 10.0 Tf ET

is rendered correctly justified in Chrome viewer and Foxit Reader.

But the same PDF document in Acrobat Reader and Adobe Acrobat 9.0 is only showing "Lorum dolar, June".

So "Ispum", "etc" and "4th" are missing.

Acrobat Preflight reports the following error:

Any ideas?

Thank you in advance

How to recover incomplete cmap?

forums_noreply@adobe.com — Tue, 13 May 2014 12:40:53 GMT

I printed a Microsoft Word file as a PDF file by Distiller with an embed SakkalMajalla truetype font. I want to extract unicode texts from the PDF file. I found ToUnicode misses part of mapping. For example, CID 06B4 doen't have any mapping. I guess 06b4 should be mapped to U+0644. There are some substitutions in SakkalMajalla. So uni0644.medi (U+FEE0) is replaced by liga.0758.medi.alt1 (U+10354). Why can't Distiller deal with the situation? How can I recover missed mapping from PDF objects except ToUnicode? Thanks

P.S. I also asked the question couple days ago. Please see Re: Is it a bug of Distiller? I haven't got answers. I don't have privilege to move or delete that discussion. Sorry for asking a question in two communities.

I have an application for the decryption of pdf passwords for 128 bit Rc4 and 128 AES. In this, i am doing 50 times MD5 using an encryption key. Its working well with this approach. But in case of 256 bit AES password security, It creates problem. What is the difference between 128 bit AES and 256 bit AES algorithms ? Please tell me what are the algorithmic steps for 256 bit AES password security ??

change font in DA of FreeText Annotation

forums_noreply@adobe.com — Fri, 04 Apr 2014 17:42:38 GMT

I am trying to change the default appearance (the DA entry) of a FreeText annotation. To begin with, I can't find anywhere in Acrobat to change the font of a FreeText annotation.

PDF File with Run Length Encoding?

forums_noreply@adobe.com — Tue, 25 Mar 2014 14:53:10 GMT

Would anyone have a PDF file containing text streams compressed in Run-Length Encoding? I need one to test a decompressor. I know they are probably rare and not used anymore which is why one is so difficult to find.

If you do have one could you attach it in a reply or refer me to it.

Example font subset with non-unicode output

forums_noreply@adobe.com — Fri, 21 Mar 2014 10:15:53 GMT

Hi,

I am searching for an example to use a TTF Font as font subset in PDF but without UTF16 encoding.

Is this even possible?

Something similar to

But how does the rest should look like?

Form field info not showing up, unless field is clicked? (again)

forums_noreply@adobe.com — Mon, 03 Mar 2014 23:37:59 GMT

We're using a pdf library called Sync Fusion to automate some fillable fields in a pdf but after the text has been placed it is not visible due to the form field high-lighting.

So far we have tried the 3 things below but nothing has solved this issue.

changing the fore/background color of the fillable fields to selected colors
disabling multiline fields
applying "mac fix" scripts

Anyone have any other ideas that might fix this? We're going to try a different pdf library next.

Indexed png transparency using /Mask

forums_noreply@adobe.com — Sun, 23 Feb 2014 14:13:38 GMT

Hi,

is it possible to use an indexed png's palette and accompanying transparency data to display a masked image? I've seen enough evidence in other opensource pdf libraries to suggest that it's possible, but am having trouble getting it working myself.

The indexed PNG's i've tested all contain an array of palette data and an associated array of transparency values.

I'm able to successfully display the png in a pdf, when only using it's palette and excluding the transprancy. The transparent parts of the image are displayed as black, as expected . The outuput is,

17 0 obj

<</Type /XObject

/Subtype /Image

/Width 16

/Height 16

/ColorSpace [/Indexed /DeviceRGB 15 18 0 R]

/BitsPerComponent 4

/Filter /FlateDecode

/DecodeParms <</Predictor 15 /Colors 1 /BitsPerComponent 4 /Columns 16>>

/Length 155>>

stream

--------------- BINARY IMAGE DATA ---------------

endstream

endobj

18 0 obj

<< /Length 48>>

stream

--------------- PALETTE ARRAY VALUES AS BINARY ---------------

endstream

endobj

But as soon as i try an add the transparency array, nothing gets displayed and i get an error when opening the pdf that says 'An error exists on this page'. The transparency values for the indexed image are as follows,

[255, 255, 192, 192, 160, 160, 128, 128, 96, 96, 64, 64, 32, 32, 0, 0]

I've followed the spec, 8.9.6.4 Colour Key Masking, although i'm not sure if there should be a difference between 'min' and 'max' or whether it's just the same value duplicated? From the logic i've seen in other pdf generation libraries, it appears to be the latter.

This is the non working output i get, when attempting to use the above array of transparency values as a mask,

17 0 obj

<</Type /XObject

/Subtype /Image

/Width 16

/Height 16

/ColorSpace [/Indexed /DeviceRGB 15 18 0 R]

Some characters extracted from pdf hasn't corresponding unicode in its font

I extracted font form pdf(arabic text) and after I opened this font I found that there are some characters hasn't corresponding unicode although the other has!

I ask about why these characters hasn't corresponding Unicode such as remaining characters? and how PDF read these characters and display it in its file although it has't unicode? because I can't get these characters outside PDF!.

This image show part of font I extracted has characters with no unicode(question mark instead).

page height is zero

forums_noreply@adobe.com — Thu, 30 Jan 2014 08:33:21 GMT

We're building a pre-flight tool to check page orientation and auto-rotate to consistantly build right reading books whether or not the page is landscape or portait but we're coming up with pdfs with MediaBox[0 -612 792 0] and getting page height = 0 and then the tool fails. We don't seem to be able to fix this programmatically. /Rotate = 0. Most of these PDFs are 1.6 but It was noticed that in PDF version 1.6 there is no mediabox and instead just has /BBox. Is there some significance to this? There doesn't seem to be a /Rotate either. I believe these pdfs are created programattically via some API rather than through InDesign or Distiller. We're trying to find a consistent way of determinig page size to do our calculations and/or be able to repair a pdf prior manipulation.

Any ideas how we should go about this? We are using a 3rd party API to do the work but this seems an issue with the actual PDF vs. the API, at least at this point.

in browser- URL of PDF where it imports FDF data

forums_noreply@adobe.com — Mon, 27 Jan 2014 11:34:21 GMT

I want to bring up my browser - put the URL of a PDF on a server that has fillable fields - and have the PDF automatically bring in the contents of an FDF file to populate the fields defined in the FDF file.

There is ADOBE documentation of doing something like this:
http://www.mydomain.com/abc.pdf#fdf=datafile.fdf

That's all I want to do. Simple.

In detail - in a PHP program I want to create the FDF file just using fopen and fwrites - no additional packages - then my JavaScript calls an already created PDF file on the web with the PDF when brought up on the server side automatically imports the FDF my program created a few seconds ago.

I do know about fdf_create in PHP but unfortunately the server I'm on is cpanel based and the hosting company cannot load a library for fdf_create related calls.

I cannot seem to get this working. I've called Adobe tech support. A few months ago I reached someone who actually said "You've reached the right person. Yes that is doable." and they confirmed what I wanted to do. But since then the Adobe people I call don't seem to understand what an FDF file is even though that is what Adobe uses to communicate and has it in their documentation as http://......abc.pdf#fdf=xxx.fdf

Now I've even eliminated the step/chance that I've not created my FDF file properly. I've gone into Acrobat Pro and done an extract to an .FDF file. Then I've tried http://www.myweb.com/abc.pdf#fdf=theAcrobatExtractedFile.fdf and it still ignores the contents of the FDF file.

I've also tried http://www.myweb.com/abc.pdf#fdf=http://www.myweb.com/extractedfile.fdf fully qualifying the location of the FDF file.

Help! This is important. Thank you.

PDF Stream Extent?

forums_noreply@adobe.com — Fri, 17 Jan 2014 10:57:39 GMT

Hello everyone.

I'm trying to interpret exacty what is and isn't included in a PDF stream and to date am still confused. I'll paste a section of the ISO3200 - 1 PDF reference below.

I'm not sure, but these statements appear to contradict each other.

So I have a stream which specifies a lenghth of 2215 bytes in its compressed form.

There is a carriage return and a line feed at the start and end of the stream data falling between the 'stream' and 'endstream' keywords.

So my data looks like this : stream CR LF Data Data Data CR LF endstream Keep in mind that CR = Carriage Return and LF = Line feed

Before I remove the CR and LF from each end of the data the total size of the stream is 2217 bytes (between the 'stream' and 'endstream' keywords. From the first paragraph below it appears that I am reading the data between the Carriage return and line feed characters at each end which brings the compressed size down to 2213 bytes (not 2215 as the stream 'Lenght' specifies.

If I follow the second paragraph from Table 5 in relation to Stream Lenghth, it appears that only the carriage return and line feed at the end of the stream are removed. So the stream to be decompressed would look like this: CR LF Data Data Data . This in fact adheres to the Stream Lenght specification for that stream which is 2215 bytes?

When decompressing a stream, what should and shouldn't be included? Cut the CR and LF from the start or the end ,,, or both? Note the red bolded section below: "lie between the end-of-line marker (I assume this means not inclusive). Like saying, stand between those two people (this doesn't mean stand on these two people and centre yourself). Yet... the green bolded area in the second section doesn't mention the initial white space?

Perhaps this is what it means. The first whitespace character after the 'stream' keyword and the whitespace character preceding the 'endstream' keyword are ignored so the stream looks like this:

Original Stream Data before removing whitespace: CR LF Data Data Data CR LF

Actual Stream data to be decompressed (whitespace removed): LF Data Data Data CR

That last option produces a stream of 2215 bytes as well.

Thanks

Under 'Stream Objects - General'

The keyword stream that follows the stream dictionary shall be followed by an end-of-line marker

consisting of either a CARRIAGE RETURN and a LINE FEED or just a LINE FEED, and not by a CARRIAGE RETURN alone. The sequence of bytes that make up a stream lie between the end-of-line marker following the stream keyword and the endstream keyword; the stream dictionary specifies the exact number of bytes. There should be an end-of-line marker after the data and before endstream; this marker shall not be included in the stream length.

AND

From table 5 in relation to the stream Length.

(Required) The number of bytes from the beginning of the line

following the keyword stream to the last byte just before the

keyword endstream. (There may be an additional EOL

marker, preceding endstream, that is not included in the count

and is not logically part of the stream data.) See 7.3.8.2,

"Stream Extent", for further discussion.

Is it possible to control the height of the Portfolio panel via the PDF Portfolio itself?

forums_noreply@adobe.com — Tue, 14 Jan 2014 07:13:38 GMT

Hi All,

Is it possible to embed into a PDF Portfolio kind of a directive to Adobe Acrobat Reader what should be the height of the Portfolio panel (red line on the image below)?

The idea, basically, is to adjust the height of the panel to the number of files in the portfolio.

Alternatively, is there a way to embed a directive to open by default the Layout pane instead of the Files pane?

Thank you all in advance for assistance!

Change the image under Form XObject to the first layer

forums_noreply@adobe.com — Mon, 30 Dec 2013 13:17:28 GMT

Hi here

The right column is the file before structure optimization, all the 5139 images is encaptured in one form(fm0).

The left column shows the structure in which all the images are changed to fist laye under XObject.

The change from right to left would make difference for specific environment like:

1)Acrobat Pro 9 would open the file after change.

2)Some workflow like ONYX Thrive could handle.

The form content actually is not repeatable,I would think it's a wrong application of Form XObject ,leading to nested XObject.

I am not a programmer so I would like to see whether it's possible in high level application to optimize the structure in Acrobat Pro?

If I have to use some low level tools to change, please help to comment which is would easy one for me.

Many thanks

Reading a PDF stream for LZW decompression?

forums_noreply@adobe.com — Sun, 08 Dec 2013 18:28:47 GMT

Hello.. I'm really struggling here.

I am currently using the Rosetta Code implementation for LZW decompression (C++). This implementation requires numerical imput. That is.. the input in it's compressed state is in numerical form.. a series of numbers. My problem is this:

I want to read the compressed LZW stream (compressed only in LZW and notencoded in ASCII 85) into a buffer and that is then passed to the decompression algorithm for decompression. I open the pdf in binary mode, read each character and convert it to an int and load each integer into the buffer . Once the buffer (which is an int vector) is loaded, I pass this to the algorithm for decompression.

Unfortunately the data will not decompress. I seem to get the same output as I put into it in a character form. I have included white space (noskipws) and also tried the opposite. I have also tried (using bitwise shift operation) to create 12 bit chunks and then loading those into an int vector. This isn't working either. I'm thinking it has something to do with how I am reading the data in the first place. What do all these little glyphs represent (in the compressed stream)? How do I go about reading compressed data into a buffer if the algorithm I am using requires numberical input common to LZW compression?

Should I include white space? How should I read the compressed data?

Any clues would be greatly appreciated.

Thanks very much.

PC users can't save PDF form data from form created on Mac

forums_noreply@adobe.com — Thu, 07 Nov 2013 18:47:49 GMT

I'm trying to create a PDF form for a client that will be accessing the form on a PC. However, when the client opens the form, a message appears saying that any data filled in the form cannot be saved and the document must be printed. If the client tries to "Save As" a message appears saying the form will be saved without the data. This defeats the whole purpose of using PDF forms.

What can I do to allow my client to save data in the form? When I check the permissions on my end, there is no security and no restrictions.
