Wrong colors after converting of some *.pct (PICT) images.

When I try to convert such *.pct images to *.jpg (or to another format):

Code: Select all

$ identify -verbose PICT.pct | grep -ie format -e colorspace
  Format: PICT (Apple Macintosh QuickDraw/PICT)
  Colorspace: RGB

$ convert -size 3072x2048 -quality 100 -colorspace RGB PICT.pct PICT.JPG
I get image with strange (wrong) colors. [http://narod.ru/disk/25469639000/PICT.JPG.html]
From the most of known image converters and viewers I've found only two wich can correct view/convert these images: ImageConverter Plus (but in small resolution) and QuickTime (but can't convert).

Old version of ImageMagick's Converter (6.3.4 05/11/07 under wine) is more successful but with color bads. [http://narod.ru/disk/25470983000/PICT_old.JPG.html]

I guess the file [http://narod.ru/disk/25468836000/PICT.pct.html] is not corrupted, because I have hundred files with these symptoms.

Are there some workarounds?

Thanks in advance.

We can reproduce the problem you reported. It may be some time before we get around to fixing the problem since the PICT image format is difficult to work support.
