Might it be that the PS6 and CS SDKs were the last ones to include the Photoshop file format specification?

I'm looking at the CS4 SDK and I don't see the Photoshop file format as one of the PDFs included in the 'documentation' directory. 

Is the PSD file format part of the SDK docs or does it have to be specially requested? If the latter, from where?

Tom,

I was out on vacation when you sent this email.

No, I never received a copy of the modern File Format PSD specification.

I sent an email to Bryan Hughes, but never heard back.  The request URL

in the docs just redirects to the main developer page and there is no

clear direction there.

The PSD docs found in SDK at least through version CS have numerous bugs and omissions. It may save you a few hundred hours of trial and error resolving some of these, if you refer to my source code at http://telegraphics.com.au/svn/psdparse/trunk ; contact me if you need more specific help.

Thank You very much, mr. Ruark.

I cant however access  http://www.stage.adobe.com/devnet/photoshop/.  I get Access Denied. Should I register somewhere?

Also, I downloaded the latest SDK and the docs state "You need to request the Photoshop File Formats documentation explicitly".

Is this (still) the case? Will the CS5-updated version be made public.

Thank You.

I wouldn't get your hopes high for any CS5 related material. The most recent references are to CS3, as far as I can see, and the document is dated July 2007. It is basically the same incomplete, buggy file that is familiar from old SDKs. You could use it to get the most basic elements of a document, as long as you are prepared for hours of trial and error as well, but most features post-5.0 are either described as black boxes, or left out entirely. Clearly nobody inside Adobe uses this document or is properly updating it for third parties.

Denied here too, but I think these documents are restricted to program participants of some kind?

OK! now I can get to that page but since the most recent information there dates from April 30, 2010 and Tom's post dates from Nov 8, 2010 I presume the answer to my original question is "No"

Hopefully we'll reach "soon" any time... soon...

The way I see it it is still the same old thing:

1. Go to http://www.adobe.com/devnet/photoshop.html

2. Download Photoshop CS5 SDK

3. Open documentation.html

4. "Frequently Asked Questions" on the left

5. "2.8 Where is the Photoshop File Formats.pdf file?

You need to request the Photoshop File Formats documentation explicitly.  In your request make sure you explicitly ask for the "Photoshop File  Formats.pdf" file"

6. Click link provided: http://www.adobe.com/devnet/photoshop/

7. stare (or go to 1.)

8. stare more

9. Serach for "format" in page

10. Search for "request" in page

11. Try to *cearfully* read every link on the page

12. FAIL

13. Go read many many forum posts about the same issue

14. Eventually you might find a link that might be the holy request form

15. Write a polite request

16. Receive an mail that the team is on vacation and you will be contacted when they return

17. Do not receive any feedback half a year later

18. Forget about it until you receive a notification from the forum that the issue is still there but there is some progress

19. Remember also there is brand new SDK (CS5)!

20. Go to 1.

Hi.

I want to report about broken links in the Adobe Photoshop File Format Specification available on Adobe site at http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/

I believe the specification itself should have following address: http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/PhotoshopF ileFormats.htm because all internal links in it points to PhotoshopFileFormats.htm document which is not available on the server, so you can't navigate thru specification using chapter links.

I think that making document PhotoshopFileFormats.htm available on your web server directly (not thru redirection to default document as it is right now) should resolve the problem.

And it would be nice to have a link to PDF version (along with present HTML version) on the SDK download page too.

I am writing a C# app. and need to access the layer information.

Might anyone offer some advise?

In Layer Record, there is a variable "length of extra data field (the total length of the next five fields)"

But there are only 3 remaining variables.  What am I missing?

1) layer mask data

2) layer blending ranges

3) layer name

I am successfully reading the Layer Record by reading in "length of extra data field" in PSD with multiple layer records.

Just not sure what they mean by "next five fields".

Tried using psdParser, but the project is missing a few files, png.h, psdrecover.h, sys/erno.h, etc.

Thanks,

CT

Adobe Photoshop 6.0 File Formats Specification

I have given a task to read psd file made from photoshop cs5 from c# programming language. I had read psd file by using file format specification up to layer listings.

But now I am stucked on reading fonts on that file. After googling, I had found psd parser which reads font information for photoshop 5.0 only. But my file is on photoshop 6.0.

Please suggest me how to read font list or font details used on layers via c#? Also in which key or location font information is stored on psd binary file?

Regards,

Biran

Thanks for your suggestion.

Finally I got the font list from psd file by parsing psd file via c#.

IM happy much more..
