early draft

13:53 < SimAV> hello fschmid 
13:54 < SimAV> #3743 is appointed to you? I have stumbled over this bug yesterday and somehow need to have 
               a fix or workaround next week...
13:54 <@mrscribe> Colorize converts Spot colors to CMYK
13:55 < SimAV> "But
13:55 < SimAV> in general creating a doutone image with a spotcolour could be easily added, this
13:55 < SimAV> needs to disable the other colorfilters for this image. "
13:55 < SimAV> yes, that's what i have to do... 
13:57 < SimAV> it hasn't to be perfect yet, I just have to get out PDFs with duotone (black and a HKS color) 
               or grayscale images, no other types of images will be required...
14:00 < SimAV> I had already a look at scimage.cpp but as i don't know scribus internals i have no clue how 
               to let colorize and duotone output non-CMYK/RGB colors
14:01 < SimAV> is there some documentation available on how sccolor is used for a color consisting of a spot 
               color at 50%?
14:01 < SimAV> or just a spot color at 100%?
14:06 < fschmid> hmm, this is difficult as images are always represented as RGB or CMYK or Lab data in the 
                 pdf
14:06 < fschmid> there is no way to "colorize" a bitmap with a spotcolor in pdf
14:07 < fschmid> thats why the bug 3743 is still open
14:14 < SimAV> ok, but scribus is said to support duotone eps...
14:14 < SimAV> so a workaround would be to use a duotone eps if one can produce one?
