Accessing properties of a PSD layer throws exception
Posted: 2009-11-06T13:51:31-07:00
I'm trying to extract all the layers out of a PSD and save as separate files using the layer's name as the filename. However, when accessing the "properties" property of the Image I get the following exception:
(Mac OX Snow Leopard 10.6.1)
ImageMagick @6.5.7-0_0+q16
rb-rmagick @2.9.0_0
here's my dead simple script to duplicate:
I have no idea what this error means or even how to start debugging it. The PSD file is 9.8 MB, 320x480 px. Here are some of the other properties I was able to extract before it bombed on the 3rd layer:
any help would be much appreciated.
