Re: [Gimp-developer] Darktable plug-in in GIMP

This issue is easily handled by other RAW loading plug-ins by intercepting the input files with .tif or .tiff 
extension and running the normal GIMP loading procedure in such cases.

Here is an example from the PhotoFlow plug-in, which was originally derived from UFraw:

The plug-in works great in importing NEF to GIMP, but now when I open some

opening raw files in GIMP, i.e. launching darktable and upon exiting
exporting the file to GIMP as 32-bit EXR. This happens with some TIF files
but not with all TIF files. Is it supposed to do that?

No, it is not. The problem is that most raw formats are TIFF files with some 
extra data. For CR2 that's not a big problem, there is a way to recognize them 
(Canon was clever enough to have a unique magic for their files), other formats 
however can't be reliably distinguished from TIFFs. NEF is one of those. So 
right now the code wrongly assumes that your TIFF is a NEF and sends it to 
darktable. Until that is fixed you have to manually select the TIFF loader in 
the lower left hand corner of the open dialog.

I do remember having trouble opening some TIF files in GIMP before, I think
some older TIF files with many Photoshop layers. This might actually work
better through Darktable, anyway :-)

Happy coincidence. Maybe you can provide a sample file to bugzilla so someone 
can have a look at properly supporting them in GIMP.
