pytoshop

A Python-based library to read and write Photoshop PSD and PSB files.

Based on the specification from Adobe, but also with the help of the psd-tools source code.

Parsing of the most important tags. This is not complete, but the infrastructure is in place to add support for more quite easily.
Loading of complex nested layer structures, and the ability to edit them and write them back out.

History

Improvements:

For speed purposes, pytoshop no longer uses traitlets.
Performance improvements to the compression/decompression code.
Added support for the shmd metadata tagged block, and the ability to access it from the user.nested_layers API.

Bugfixes:

Updated the list of tagged blocks that use 8-bit lengths.
Fixed a bug where the image data would be corrupted when writing images from an input file to an output file with a different file format version.
Fixed a crash when the input file contains no layer group ids.
Allow Numpy arrays of shape () in place of scalars for constant images.

Improvements:

pytoshop now runs on Python 2.7, in addition to 3.4 and 3.5.
Many of the image resources types are now handled directly, rather than through a generic bytes-only interface.
Major speedups in compression codecs.

Bugfixes:

Saving a layer with a constant color (in nested_layers_to_psd) now works correctly.
Unicode string decoding now properly handles trailing zeroes.
The “name source” on layers (when created from nested_layers_to_psd) would point to the wrong source, but is now fixed.
Fix a bug when writing a layer of width 1.
