Hi,
I currently work with special image formats used in electron microscopy. I would like to be able to open, manipulate and save those files using The Gimp. Could anybody give me some pointers on how get started writing input filters?
Thanks

there is a plugin, p2m that saves images into several different cad file types. i don't know which format you are working with, but this plug-in saves in four different file formats and might give you some clues.

http://registry.gimp.org/plugin?id=338

there are other plug-ins for other file formats at the registry. this one comes with the most, iirc.

Hi Mario,

The most difficult part is undoubtedly the image format itself, as opposed to the GIMP part. I would suggest taking a fairly trivial image format (say pnm), and stripping it's plug-in save & load routines, and replacing them with your custom routines.

The source code for the pnm plug-in is in plug-ins/common/pnm.c.

Hope this helps, Dave.
