Migrating to 1.9

psd-tools 1.9 switches to NumPy based compositing.

version 1.8.x:

psd = PSDImage.open(filename)
image = psd.compose()
layer = psd[0]
layer_image = layer.compose()

version 1.9.x:

psd = PSDImage.open(filename)
image = psd.composite()
layer = psd[0]
layer_image = layer.composite()

NumPy array API is introduced:

image = psd.numpy()
layer_image = layer.numpy()

Migrating to 1.8

There are major API changes in version 1.8.x.

Note

In version 1.8.0 - 1.8.7, the package name was psd_tools2.

File open method is changed from load to open().

version 1.7.x:

psd = PSDImage.load(filename)
with open(filename, 'rb') as f:
    psd = PSDImage.from_stream(f)

version 1.8.x:

psd = PSDImage.open(filename)
with open(filename, 'rb') as f:
    psd = PSDImage.open(f)

Children of PSDImage or Group is directly accessible by iterator or indexing.

version 1.7.x:

for layer in group.layers:
    print(layer)

first_child = group.layers[0]

version 1.8.x:

for layer in group:
    print(layer)

first_child = group[0]

In version 1.8.x, the order of layers is reversed to reflect that the index should not change when a new layer is added on top.

Primary PIL export method is compose().

version 1.7.x:

image = psd.as_PIL()

layer_image = compose(layer)
raw_layer_image = layer.as_PIL()

version 1.8.x:

image = psd.compose()

layer_image = layer.compose()
raw_layer_image = layer.topil()

Data structures are completely rewritten to support writing functionality. See psd_tools.psd subpackage.

version 1.7.x:

psd.decoded_data

version 1.8.x:

psd._record

Pymaging support is dropped.
