Is it possible to generate CMYK Tiff Images using the poppler
utils ?

I've tried pdftoppm from the latest git pull put it end up somewhere
when in TiffWriter  which complains that "Mode 6 is not supported".
As You perhaps already encountered, William created a patch for it (s.
https://bugs.freedesktop.org/show_bug.cgi?id=54896).

Yes -- thank you. The patch worked just fine. It should be included
into the master.


How's about generating bitap images with spot color plains ? Is
that on the road map ?
No, at least not on my roadmap. There are only a very few formats and
programs which support bitmap images with spot color planes. The only
formats for bitmap images I know are TIFF (really seldom used with spot
planes and if a TIFF contains spot planes most programs just ignore it
or complains about it) and PSD (Photoshop native) which has a better
support for it but is even more rarely supported. So it makes no much
sense to create a bitmap image with spot planes.

It's actually not about supporting it in a real file format. But generating real spot color bitmaps would give great support for
raster image processors for printer devices.

Thanks for the reply

Sebastian
