IM can't read its own PSD files if it contains layers

[jn0101]

Using ImageMagick 6.4.5 2009-06-04 Q16 OpenMP on Ubuntu Linux and a PSD file with 3 layers:
(availabable at http://javabog.dk/filer/psd/nem_154049_fc_JNSMALL.psd)

• $ convert nem_154049_fc_JNSMALL.psd x.psd
  $ convert x.psd y.psd
  convert: maximum channels exceeded `x.psd' @ coders/psd.c/ReadPSDImage/858.
  convert: missing an image filename `y.psd' @ wand/convert.c/ConvertImageCommand/2710.
  $

Identify correctly shows the 3 layers:

• $ identify nem_154049_fc_JNSMALL.psd
  nem_154049_fc_JNSMALL.psd[0] PSD 248x239 248x239+0+0 8-bit DirectClass 346kb 0.190u 0:02
  nem_154049_fc_JNSMALL.psd[1] PSD 248x239 248x239+0+0 8-bit DirectClass 346kb 0.190u 0:02
  nem_154049_fc_JNSMALL.psd[2] PSD 24x14 24x14+158+200 8-bit DirectClass 346kb 0.180u 0:02

I can also extract each as tiff and view them in any tool. So reading is OK.




Ive just checked out the latest SVN version. Same result:

• $ /usr/local/im/im6.5.4/bin/convert nem_154049_fc_JNSMALL.psd x.psd
  $ /usr/local/im/im6.5.4/bin/convert x.psd y.psd
  convert: maximum channels exceeded `x.psd' @ psd.c/ReadPSDImage/856.
  convert: missing an image filename `y.psd' @ convert.c/ConvertImageCommand/2772.

However, it seems reading is broken in newest version: The layers are not found:

• $ /usr/local/im/im6.5.4/bin/identify nem_154049_fc_JNSMALL.psd
  nem_154049_fc_JNSMALL.psd PSD 248x239 248x239+0+0 8-bit DirectClass 346kb

I might be of interest to you that open source GIMP seems to be able to handle layers in PSD files.

Thanks for a great tool!

The default is to ping the image which is quite efficient but only gets attributes from the first image. To get all the layers, type

• identify +ping nem_154049_fc_JNSMALL.psd

Thanks for your reply.

You are absolutely right, using +ping makes newest IM also identify all 3 layers in the original file.

Code: Select all

$ /usr/local/im/im6.5.4/bin/identify +ping nem_154049_fc_JNSMALL.psd
nem_154049_fc_JNSMALL.psd[0] PSD 248x239 248x239+0+0 8-bit DirectClass 346kb 
nem_154049_fc_JNSMALL.psd[1] PSD 248x239 248x239+0+0 8-bit DirectClass 346kb 
nem_154049_fc_JNSMALL.psd[2] PSD 24x14 24x14+158+200 8-bit DirectClass 346kb 

Thus, "only" remains that IM can read its own PSD files

Code: Select all

$ /usr/local/im/im6.5.4/bin/identify  x.psd 
x.psd PSD 248x239 248x239+0+0 8-bit DirectClass 388kb 

(I suppose this is becaurs the extra layers are not examined when not using +ping)

Using +ping gives the same error as in the older 6.4.5:

Code: Select all

$ /usr/local/im/im6.5.4/bin/identify +ping x.psd 
identify: maximum channels exceeded `x.psd' @ psd.c/ReadPSDImage/856.

We're working on the problem. We'll have a fix within a day or two.
