Hi,
I have a GIF file (which I have upload to:
http://www.bright-interactive.com/downloads/test.gif), which I am trying
to convert to a TIFF file that will open in Windows Picture and Fax
Viewer.
When I convert it using Image Magick 6.2.3 on Linux, using:
convert -compress LZW test.gif test.tif
all is well - the image opens fine.
However, if I try the same command using Image Magick 6.2.4 or 6.2.9 on
Windows, the file fails to open.
The file also fails to open if I use Image Magick 6.2.9 on Linux, which
suggests it is an issue to do with the version.
Running
identify -verbose test.tif
on the converted files shows a few differences, for example:
Class: PseudoClass (for the TIFF created with version 6.2.9)
Class: DirectClass (for the TIFF created with version 6.2.3)
This may or may not be relevant!
- What changed between versions 6.2.3 and 6.2.4 that could have caused
the format of the resulting TIFF files?
- The TIFFs open fine in Photoshop/GIMP. Does anyone know under what
circumstances Windows Picture and Fax Viewer doesn't open images?
Any help will be much appreciated!
Thanks,
Martin
