Re: [Gimp-developer] Problem with CMYK TIF
As Ville pointed out, there's no alternate color-space support in Gimp 1.x so it is not possible for the TIFF loader (which is maintained by me) to simply import the raw CMYK data from the TIFF. The same applies to LAB or any other colorspace with a non-trivial transform to RGB. Instead, libtiff is asked to convert the data on the fly to RGBA. The problems you're seeing (upside down image, progress is inaccurate/ non functional) are due to limitations on (a) the libtiff APIs and (b) my investment of time needed to work around them. Some future version of this loader might do a better job, or some future version of the Gimp might support CMYK, in any case I'm sorry but this probably won't be resolved during the 1.2.x series. To find out more about your TIFFs get "tiffinfo", probably included with recent versions of the tiff libraries. PS The dialog box who's contents you don't remember warned you that this would happen - read the warning dialogs! ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer
Re: [Gimp-developer] Problem with CMYK TIF
Interesting: Somehow it could read the file (There was a dialog box which contents I can't remember, but it was about file format. I hit OK there) Can I find out more about that (my) particular TIF, possibly within GIMP. Maybe I could send you the start of the file (the whole image is 18MB, so not ideal for distributing)... Could it be that the TIF uses LAB colors, not CMYK?
