• Read and write of the low-level PSD/PSB file structure

• Raw layer image export in NumPy and PIL format

Limited support:

• Composition of basic pixel-based layers

• Composition of fill layer effects

• Vector masks

• Editing of some layer attributes such as layer name

• Blending modes except for dissolve

• Font rendering

Installation

Use pip to install the package:

pip install psd-tools

Getting started

from psd_tools import PSDImage

psd = PSDImage.open('example.psd')
psd.composite().save('example.png')

for layer in psd:
    print(layer)
    layer_image = layer.composite()
    layer_image.save('%s.png' % layer.name)

Note

PSD specification is far from complete. If you cannot find a desired information in the documentation, you should inspect the low-level data structure.
