Re: What should be the behavior of Background with shfil

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

Can you post the PDF? Are you sure that the conversion is to a ‘sh’ and not a Pattern?

Re: What should be the behavior of Background with shfil

forums_noreply@adobe.com — Thu, 13 Nov 2014 16:32:34 GMT

Then I assume that the behavior of the distiller is correct.

What would be the behavior of PDF Viewer application? It is showing the background color when I use acrobat profession 11 to view the converted pdf from the postscript shared earlier.

The Pdf specification says that this entry would be consider only when the shading dictionary is used as a part of pattern color space but should ignore when used by sh operator.

Is it something that the acrobat viewer behaves wrongly or I am missing some thing.

Thanks

Execution of shfill can ignore it, but PDF conversion of Postscript isn’t the same as direct execution.

Re: Axial shading pattern with different alpha

Alpha is already DeviceGray since you just get a single channel.

Re: Axial shading pattern with different alpha

forums_noreply@adobe.com — Thu, 13 Nov 2014 02:48:18 GMT

I successfully made it work using /S /Luminosity + /CS /DeviceRGB + stream in /DeviceRGB.

I'm wondering what is /CS and stream for /S /Alpha? If /Alpha, should I use DeviceGray and alpha stream same as Image soft mask?

I first tried /S /Alpha but didn't succeed.

Re: Axial shading pattern with different alpha

forums_noreply@adobe.com — Wed, 12 Nov 2014 23:09:50 GMT

You would need to compute where those colors are used and create the proper mask to represent it.

Re: Axial shading pattern with different alpha

forums_noreply@adobe.com — Wed, 12 Nov 2014 23:03:11 GMT

Ok, thanks for your help and I've resolved the type mixing mistake.

Another question if I would like to set different alpha for different areas (in the previous pdf). For example, black 0.2, red 0.5. blue 0.3 and green 0.7. Which /S (Mask) and /CS (Group) do you recommend to use in dictionaries? Currently I'm using Alpha for /S and DeviceGray for /CS.

Thanks again.

Is the soft-mask dictionary right?

For 31 0 obj, it should be a Transparency Group XObject.

Re: Axial shading pattern with different alpha

forums_noreply@adobe.com — Wed, 12 Nov 2014 16:14:19 GMT

Ok, thanks.

The soft-mask dictionary still has incorrect Subtype key. And it is a stream, it should be a dictionary.

G should be a form XObject -- a stream. I think you are mixing up this with the transparency group attributes dictionary, which is not an XObject, but is found via the Group key in the XObject.

Please post a link to the actual file on a file sharing site, your site, or acrobat.com when you have a stream... though there are clear unbalanced << >> marks in what you post.

The Mask is a type of form XObject, so the stream must be marking operators which make the soft mask you need (by painting anything at all with suitable alpha, only the alpha is used). There are other key value pairs which are required for a form XObject.

Re: Axial shading pattern with different alpha

forums_noreply@adobe.com — Wed, 12 Nov 2014 15:22:30 GMT

Thank you for your reply.

Actually what I'm doing is drawing a rectangle and filling using axial shading pattern (/GS0).

Before alpha involving, everything works fine. (removing 40, 17 and /SMask 17 0 R in 18)

PDF Axial Shading Pattern ranging opacity shows we can add a SMask in the ExtGState to achieve the alpha value and I read the PDF 1.4 reference.

My current stream is based on the generation of soft-mask Image. Is there any sample code showing how to generate the stream?

My latest try and please correct me if I made some mistakes:

17 0 obj

/Type /Mask

I don't examine PDF fragments in detail, the entire PDF should be shared outside the forum. But I can see at a glance many problems. Several leap out:

1. A stream with no Length

2. In several places, a Subtype key which is not shown in the spec

3. Mixing up transparency group XObject with transparency group attributes dictionary

4. A form XObject with invalid marking operators (just a series of "3" characters)

Re: CIDFont and PDF

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

You could try running it through Distiller and see what it does. Not as satisfying as finding the answer from study of the spec, but interesting nevertheless. If it is printable PostScript, Distiller must be able to do something with it.

CIDFont and PDF

forums_noreply@adobe.com — Tue, 11 Nov 2014 14:20:43 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

Re: PDF CID keyed font support

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

thanks ever so much for the info.

One last thing - I said earlier that I thought I had examples of CIDFonts that had non CFF data, I think I may well have got that wrong.

To your knowledge, does the CIDFont spec support type 1 charstrings (like you find in type 1 fonts)?

Re: PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 15:22:49 GMT

ISO Standard is the document you should be using – it supersedes all of the Adobe references.

Correct. You need to convert the T1->CFF for use in a CIDFont.

(and yes, PS also did CIDFonts of more complexity)

Re: PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 14:35:02 GMT

I thought CIDFonts existed in the PS world well before PDF, and also, in the PS world, CIDFonts are more complex because they aren't limited to a single descendent font.

My understanding of the PDF spec is that a composite font has only 1 descendant unlike in PS. But that's a bit off topic.

AFP (a nasty old IBM transactional print language) will generate CIDFonts which use type1 font (not CFF) as a descendent - these CIDfonts are handled by FreeType.

the problem I have is how to embed them in PDF (when converting the AFP stream to PDF).

The bit you quote from the ISo standard is really clear, I agree, I had been using the PDF reference manual which doesn't specify CFF for composite based in type1, it says:

"•A Type 0 CIDFont contains glyph descriptions based on the Adobe Type 1 font format"

based on the ISO spec and what you tell me, I guess it is clear that you cannot represent a CIDFont which is based on a non-CFF font program in a PDF file unless you convert the Type1 font to CFF. Is that right?

Thanks

AFO

Re: PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 14:22:49 GMT

ISO 32000-1:2008 (aka the PDF standard) is very clear on the topic:

9.7.4.1 General

A CIDFont program contains glyph descriptions that are accessed using a CID as the character selector. There

are two types of CIDFonts:

• A Type 0 CIDFont contains glyph descriptions based on CFF

NOTE The term “Type 0” when applied to a CIDFont has a different meaning than for a “Type 0 font”.

• A Type 2 CIDFont contains glyph descriptions based on the TrueType font format

I am confused, however what print language you are converting to PDF that has a CIDFont, since that is a PDF-centric concept.

Re: PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 14:14:12 GMT

can I add a little background to my question.

We have a print language conversion application that can receive fonts from a variety of sources.

One such source will generate CIDFonts that contains type 1 font programs and these are perfectly valid, they can be rendered by the FreeType library etc.

however, if transforming a print stream to PDF, I am worried that PDF cannot represent such a thing (non CFF, CID keyed).

If I know that this is the case, then I know that we have the big problem of Type1 to CFF conversion in order to embed the font in pDF.

This is what has prompted my question.

Re: PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 14:05:44 GMT

ok, let me rephrase my question a little.

please explain why the fact that a type1 font doesn't know about Unicode means that a CID keyed font has to use a CFF embedded font program rather than, for instance, a CIDFont that uses a type 1 font program.

Re: PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 13:44:24 GMT

You don’t.

Re: PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 13:35:57 GMT

thanks for the reply, but I don't quite understand your answer.

Could you explain to me how the Unicode issue affects and explains your assertion that only CFF is supported?

My understanding is that a composite font in PDF has to use a CMap to generate a numeric CID, the problem with a type 1 font would then be that glyphs are selected by name - how do you

map a CID to a glyph name?

Re: PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 12:08:34 GMT

You can only use CFF-based Type 1 fonts for CID, since a classic Type 1 didn’t know anything about Unicode.

PDF CID keyed font support

forums_noreply@adobe.com — Mon, 10 Nov 2014 12:00:44 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?

Re: Form XObjects without Resources - do we ignore ancestor forms?

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

Yes, that's what prompted this question. We use a fairly popular PDF library to reorder and combine documents from various files. The original Page becomes a Form and the Resources inheritance ends up like my question. It doesn't attempt to add the 'missing' Resources to fix it up (can't really blame them).

Re: Form XObjects without Resources - do we ignore ancestor forms?

forums_noreply@adobe.com — Sat, 25 Oct 2014 00:50:21 GMT

Me too. I should also note that many utilities will not respect inheritance from page object if they do certain transformations such as convert a page to a form XObject (e.g. for placing as a graphic). I just point this out in case, in future, anyone reading this sees a shortcut and is tempted.

Re: Form XObjects without Resources - do we ignore ancestor forms?

forums_noreply@adobe.com — Sat, 25 Oct 2014 00:43:16 GMT

Yes I'll agree with that, what I really meant is we shouldn't be surprised if we get errors. I work a lot with printers and generally I'm happier if a printer just fails and gives me a chance to fix the file myself, rather than guessing what to do.

Re: Form XObjects without Resources - do we ignore ancestor forms?

forums_noreply@adobe.com — Sat, 25 Oct 2014 00:15:37 GMT

I take issue with "We should therefore get a missing font error as the PDF is invalid". If a PDF is invalid (as it would be) the behaviour is undefined. Unless you are using software that claims to be a complete PDF validator, the PDF reader may take any behaviour and would be correct, including

- an error

- a default font

- missing text

- looking at the chain of form XObjects

A PDF creator should of course only make correct PDFs rather than rely on accidental or deliberate permissiveness in any particular viewer.

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

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

There are some more details in the link I posted but you can see a PDF here: http://bugs.ghostscript.com/attachment.cgi?id=11252

It happened in CS6 and CC 2014. Basically it happens if you only use invisible characters like space for a TTF font, and .notdef does not exist in the font. It looks like InDesign realises no glyph drawing details are needed so the table is zero length. It seems to be causing a printing failure and various issues with other programs so it sounds like this possibility is not well catered for in many programs, though most recover.

forums_noreply@adobe.com — Fri, 24 Oct 2014 23:55:18 GMT

Thanks for that. The PDF that prompted this query was version 1.3, so I thought it would be best to refer to that version of the spec. Does the ISO spec relate to all versions or just the later ones?

Re: Form XObjects without Resources - do we ignore ancestor forms?

forums_noreply@adobe.com — Fri, 24 Oct 2014 14:22:59 GMT

First – the version of the PDF spec you are using is VERY OLD. You should be using the international standard – ISO 32000-1:2008 as it is the official document at this time.

Second – the topic you raise has come up many times on the ISO committee and how to clean up and clarify that section. You will find the version in 32000 much clearer and more specific on how to handle it. Which is that if there is no Resources dictionary at all – then you inherit. If there is a Resources dictionary, then regardless of whether it has fonts (in your case), you do not inherit.

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

forums_noreply@adobe.com — Fri, 24 Oct 2014 06:02:10 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.

Form XObjects without Resources - do we ignore ancestor forms?

forums_noreply@adobe.com — Fri, 24 Oct 2014 04:00:39 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."

If customer uses export settings it eliminates many Features that are not needed for printing.

Just having the export settings used would be an easy check before we throw our battery of preflight checks against it.

Our prepress Dept is sometimes too busy to preflight all of the files and tell the customer if they can leave for vacation (actual issue) or whatever is their whim.

So maybe it does matter what settings were used. (not trying to sound grumpy)
