Description Christopher Yeleighton 2011-03-24 10:40:11 UTC 
User-Agent:       Mozilla/5.0 (compatible; Konqueror/4.6; Linux) KHTML/4.6.0 (like Gecko) SUSE

ImageMagick incorrectly saves images to indexed TIFF with a 4-color palette.  The result is stretched horizontally, cropped and smudged.  Since libtiff does not provide an alternative tool to do it, there is currently no way to produce such an image using openSuSE.

Reproducible: Always

Steps to Reproduce:
  1. { convert -size 100x400 canvas:red canvas:green +append canvas:blue +append -type Palette c4.tiff && xdg-open c4.tiff; }

Actual Results:  
  1. A red rectangle.

Expected Results:  
  1. A red-green-blue striped rectangle.
