At this time, transparency within GIF is not supported for reading or writing.
Interlaced (progressive) GIF files can be generated by supplying the INTERLACING=ON option on creation.
By default GDAL does not support the creation of LZW compressed GIF files due to the usual LZW patent issues; however, it is possible to build GDAL from source with LZW compression support if the LZW supporting version of giflib is installed.
GDAL's GIF support is implemented based on source from the libungif library written by Gershon Elbor, Eric Raymond and Toshio Kuratomi. It was written with the financial support of the DM Solutions Group, and CIET International.
