Spot Color Support for PDF Renderer
This patch provides spot color support for spot colors for the PDF renderer. It
was developed against the 0.95 codebase, so it may not be compatible with the
HEAD.
The code's rather rough and unforgiving (you need to specify the color function
with ALL arguments correctly or it will likely die), but it's sufficient for
our current production environment. Values for the alternate colorspaces
(RGB/CMYK) must be provided, with the tint pre-calculated...though I believe it
currently only actually uses one of the alternates (I think CMYK ??) for
non-PDF renderers.
With this patch applied, you may specify spot colors in your FO using the
following function:
rgb-icc(R,G,B,'#Separation',spot-color-name,tint-value,C,M,Y,K)
Here's one with real values:
rgb-icc(0,91,165,'#Separation','Reflex Blue CV',1,0.96,0.7,0.04,0)
I'm posting this here at Jeremias' request since he's working on implementing
full support for spot colors. If you're looking at this for your own fork, you
should probably review the status of his efforts first!
