Re: [Gegl-developer] gegl:convert-space

I still feel like I haven't gotten the hang on it.

Here's an example where I don't do anything with the profile - just open a tiff file and then save it again:

    $ iccdump -s -t desc -i square2.tiff
    Embedded profile found at file offset 4428 (0x114c)
    TextDescription:
      ASCII data, length 55 chars:
        0x0000: Epson V600 VSE gamma 1.8 with matrix and shaper curves
      No Unicode data
      No ScriptCode data

    $ gegl -- gegl:tiff-load path=square2.tiff gegl:tiff-save path=square2-out.tiff bitdepth=16 fp=0

    $ iccdump -s -t desc -i square2-out.tiff                              
    Embedded profile found at file offset 24788 (0x60d4)
    TextDescription:
      ASCII data, length 13 chars:
        0x0000: babl profile
      No Unicode data
      No ScriptCode data


First of all - if I don't specify bitdepth and fp in the gegl:tiff-save, gegl seems to convert the image to 
32b float. But more importantly, gegl seems to discard the original color profile and substitute its own babl 
profile.

If I try to convert the space in between:

    $ gegl -- gegl:tiff-load path=square2.tiff gegl:convert-space 
path='/usr/share/color/icc/colord/ProPhotoRGB.icc' gegl:tiff-save path=square2-out.tiff bitdepth=16 fp=0

    $ iccdump -s -t desc -i square2-out.tiff                                                                  
                                      
    Embedded profile found at file offset 33002 (0x80ea)
    TextDescription:
      ASCII data, length 13 chars:
        0x0000: babl profile
      No Unicode data
      No ScriptCode data

It doesn't seem like it converted the color. Just reassigned the profile from the scanner to its internal 
babl one.
