Python PSD layers?

Question

I need to write a Python program for loading a PSD photoshop image, which has multiple layers and spit out png files (one for each layer). Can you do that in Python? I\'ve tried

Using the win32com plugin for python (available here: http://python.net/crew/mhammond/win32/) You can access photoshop and easily go through your layers and export them.

Here is a code sample that works on the layers within the currently active Photoshop document, and exports them into the folder defined in 'save_location'.

from win32com.client.dynamic import Dispatch

#Save location
save_location = 'c:\\temp\\'

#call photoshop
psApp = Dispatch('Photoshop.Application')

options = Dispatch('Photoshop.ExportOptionsSaveForWeb')
options.Format = 13   # PNG
options.PNG8 = False  # Sets it to PNG-24 bit

doc = psApp.activeDocument

#Hide the layers so that they don't get in the way when exporting
for layer in doc.layers:
    layer.Visible = False

#Now go through one at a time and export each layer
for layer in doc.layers:

    #build the filename
    savefile = save_location + layer.name + '.png'

    print 'Exporting', savefile

    #Set the current layer to be visible        
    layer.visible = True

    #Export the layer
    doc.Export(ExportIn=savefile, ExportAs=2, Options=options)

    #Set the layer to be invisible to make way for the next one
    layer.visible = False
