Subject Re: Rasterizing of SVG file with the linked graphics fails if CMYK icc profile is specified

Without deep knowledge on this, according to a tightly related thread
[1] (which provides significant background on this), it sounds like
Batik may not yet support this; a patch [2] may help workaround some
(all?) of these limitations. Maybe Thomas can confirm and add up more
interesting feedback? :-)

Also, if you are trying to use SVG for page composition, you may want
to take a look at FOP [3], which appears to support this (at least,
this is hinted from a fixed issue [4] which the related thread [1]
refers). Jeremias can probably provide more information on this. ;-)
