psd-tools

The .PSD extension is used by Adobe Photoshop to store source image files.

This library allows developers to extract data from PSD files and use them in Python applications.

psd-tools can currently deal with images in 8bit, 16bit and 32bit channels, and also includes support for working with RGB, RGBA, CMYK, CMYKA and Grayscale graphics.

Features:

• Read header data
• Work with the PSD layers
• Work with the PSD layer groups
• Export one layer only
• Export the merged final image
• Cython extension

What is new in this release:

• Fixed synchronization in case of 8B64 signatures.
• Fixed reading of layers with zero length.
• Fixed Descriptor parsing.
• Fixed reading of images with layer masks.
• Improved mask data decoding.
• Some of the descriptor structures and tagged block constants are renamed.
• PATH_SELECTION_STATE decoding.
• The library is switched to setuptools; docopt is now installed automatically.

What is new in version 0.10:

• Scalar descriptor values (doubles, floats, booleans) are now returned as scalars, not as lists of size 1;
• Fixed reading of EngineData past declared length;
• "background color" Image Resource parsing;
• psd_tools.decoder.actions.Enum.enum field is renamed to psd_tools.decoder.actions.Enum.value;
• code simplification - constants are now bytestrings as they should be;
• Python 3.4 is supported.

What is new in version 0.9:

• psd-tools.py command-line interface is changed, 'debug' command is added;
• Pretty-printing of internal structures;
• pymaging support is fixed;
• Allow 'MeSa' to be a signature for image resource blocks;
• psd_tools.debug.debug_view utility function is fixed;
• Photoshop CC constants are added;
• Photoshop CC vector origination data is decoded;
• Binary data is preserved if descriptor parsing fails;
• More verbose logging for PSD reader.

What is new in version 0.8.2:

• Python 2.x: reading data from file-like objects is fixed.

What is new in version 0.8:

• Descriptor parsing.
• Text (as string) is extracted from text layers.
• Improved support for optional building of Cython extension.

What is new in version 0.7.1:

• Fixed typo.

What is new in version 0.5:

• Support for zip and zip-with-prediction compression methods is added;
• Support for 16/32bit layers is added;
• Optional Cython extension for faster zip-with-prediction decompression.

What is new in version 0.1.4:

• Packaging is fixed in this release.

Requirements:

• Python 2 or higher
