CMYK from Batik
Hello,
I may be asking for the moon on a stick but is there any way to get CMYK
colour output, preferably in pdf format from Batik ? I can get pdf
output using PrintTranscoder and pdf printer driver (eg.PDF reDirect)
but the pdfs are always in RGB and require a further conversion to CMYK
before they can be used to make printing plates.
Thanks,
Patrick

This is correct, however if you were to check out the code in the
"How to load an SVG resource into a java.awt.Image" thread. You would
have essentially everything you need to construct get a CMYK BufferedImage
from Batik (you will have to use the 'ColorModel' constructor for the
BufferedImage, use the 'createCompatibleWritableRaster' to get an
appropriate raster).
The one word of caution I will give is that my experience with
Java2D is that problems start to crop up once you get "off the beaten
path" and rendering to a CMYK image is almost certainly off the beat
path. Also I'm a little curious why a CMYK JPEG is any better than
an RGB (well YCbCr) unless you have support for specifying CMYK
colors. Which the above will _not_ give you.

AFAIK, none of the bitmap transcoders support the creation of a CMYK
bitmap at the moment.

Thanks for your answer Jeremias,
Can anyone tell me how to create a CMYK JPEG with the JPEGTranscoder.
I believe that this involves the use of <color-profile> tag with a
reference to an .icm file, but an example of both java and suitable svg
source would help greatly.
Thanks,
Patrick

FRF = Frequently requested feature :-)
No, the PDF output currently doesn't support CMYK. Only for CMYK JPEGs
with an ICC profile the CMYK information can be preserved, but that's
not what you're asking for. Furthermore, SVG is not really oriented
towards CMYK. I can't talk for Batik, only for FOP (Batik uses FOP code
for PDF output), but we currently can't specify colors with an ICC
profile which is the only possible route to work with CMYK colors. And
it may even be non-standard as far as I know.
Given the amount of feature requests in the past I would have thought
that someone finally sits down and starts implementing support for CMYK.
But I guess we'll have to wait a little longer for that.
