Largely transparent PNG to TIFF/PTIF corrupts image

[posterChild]

I'm back again, and unfortunately, it's to seek more help rather than to help others.

I'm trying to create a PTIF of an image and whenever I execute the following command, I get a (presumably) corrupt image:

Code: Select all

convert.exe original_framegraphic.png ptif:original_framegraphic.tif[256x256]

Alternatively, I tried to create 'just' a TIFF

Code: Select all

convert.exe original_framegraphic.png tif:original_framegraphic.tif

This results in the same type of corrupt image. The frustrating part is that for other PNG images with transparency, it works as expected.

I'm beginning to think it's the libtiff library, but want to avoid recompiling that and Imagemagick this late in my development cycle. Any ideas/alternatives to get this image to process as a PTIF without corruption?
