Legacy ImageMagick Discussions Archive

We use ImageMagick with static libs, 8 bit (based on ImageMagick-6.5.9) in a dll to convert a variety of image formats to jpg for use as thumbnails.

We have a PSD file that ImageMagick will not open via our dll. It also cannot be displayed correctly in imdisplay.exe (6.6.1-Q8). It opens fine in Photoshop CS4. Could you please advise as to what is wrong with the file or if there is a fix needed in IM?

Our client has agreed to share the file with the IM community, please treat the file with confidentiality.

I have posted the file (Image_01D.psd) to our ftp site in this directory: /ImageMagick/

It sounds as if you are on Windows. On Windows 7, running a fairly recent IM (6.6.2-4), I can't find any problems. Specifically:

identify says Image_01D.psd has multiple CYMKA images. The comand
make the files imd-0.png, imd-1.png, imd-2.png, imd-3.png. Looking at these with Gimp, the first of these is transparent except for a gray strip on the left edge. The other three are photos of a bed.

"imdisplay Image_01D.psd" shows the same as Gimp on imd-0.png.

I conclude that if you upgrade, all may be okay.

Your image displayed properly with ImageMagick 6.6.2-6, the latest release.

In 6.5.9 this value is defined:
#define MaxPSDChannels 24
so the sample image (which has 42 channels) was failing in this code:
psd_info.channels=ReadBlobMSBShort(image);
if (psd_info.channels > MaxPSDChannels)
ThrowReaderException(CorruptImageError,"MaximumChannelsExceeded");

In 6.6.3, the maximum channels has been boosted:
#define MaxPSDChannels 56
so the file now opens.

Thanks,
Graeme
