Besides these 2 documents
a) Photoshop CS File Formats Specification October 2003
b) Adobe Photoshop 6.0 File Formats Specification Version 6.0 Release 2.0 November 2000
Are there any other documents which would be helpful in understanding the PSD and PSB formats?
Is there a document/spreedsheet which shows which features are supported via Photoshop Versions
2.0 3.0 4.0 5.0 6.0 7.0 CS CS2 CS3 CS4 showing PSB and PSD features?
Where would these additional documents be located?
