The output is black. The problem goes away when you compile with the quantum set to 16. I've tried this on both my and my wife's computers with the same result.

Can anyone verify? Thoughts?

I have: Version: ImageMagick 6.3.3 04/15/07 Q16 http://www.imagemagick.org

Running convert on the TIFF to PNG produces a black image. However, it also produces the following errors:

convert: N048W093.sm.tif: unknown field with tag 33550 (0x830e) encountered. `TIFFReadDirectory'. convert: N048W093.sm.tif: unknown field with tag 33922 (0x8482) encountered. `TIFFReadDirectory'. convert: N048W093.sm.tif: unknown field with tag 34735 (0x87af) encountered. `TIFFReadDirectory'. convert: N048W093.sm.tif: unknown field with tag 34737 (0x87b1) encountered. `TIFFReadDirectory'.


Now, I noticed your original TIFF is not in RGB color space, but Indexed. I re-saved it out as an RGB file (Photoshop) and then re-ran the convert command. This time I got no errors and the PNG file wasn't black...it was what I would expect it to be, the actual image.

   Just in case the IM team needs more info...
