Python package for working with Adobe Photoshop PSD files
psd-tools is a Python package for working with Adobe Photoshop PSD files as described in specification.
Use pip to install the package:
pip install psd-tools
In order to extract images from 32bit PSD files PIL/Pillow must be built with LITTLECMS or LITTLECMS2 support.
For complete layer image composition functionality, also install NumPy/SciPy. This will be only necessary when the PSD files are saved without maximized compatibility and the image contains gradient fill:
pip install numpy scipy
from psd_tools import PSDImage psd = PSDImage.open('example.psd') psd.compose().save('example.png') for layer in psd: print(layer)
Check out the documentation for features and details.
