Hi, I am working on a front end to xicclu/colprof would like to be able to plot the graphs from xicclu in my own application. For example, my application would provide a GUI for the CMYK printer profile scenario described here: http://www.argyllcms.com/doc/Scenarios.html#PP5 In that scenario, we use xicclu as follows to evaluate black generation curves: xicclu <http://www.argyllcms.com/doc/xicclu.html> -g<http://www.argyllcms.com/doc/xicclu.html#g> -kz <http://www.argyllcms.com/doc/xicclu.html#k> -l290<http://www.argyllcms.com/doc/xicclu.html#l> -fif <http://www.argyllcms.com/doc/xicclu.html#f> -ir<http://www.argyllcms.com/doc/xicclu.html#i> PrinterBt.icm <http://www.argyllcms.com/doc/xicclu.html#p1> xicclu <http://www.argyllcms.com/doc/xicclu.html> -g<http://www.argyllcms.com/doc/xicclu.html#g> -kx <http://www.argyllcms.com/doc/xicclu.html#k> -l290<http://www.argyllcms.com/doc/xicclu.html#l> -fif <http://www.argyllcms.com/doc/xicclu.html#f> -ir<http://www.argyllcms.com/doc/xicclu.html#i> PrinterBt.icm <http://www.argyllcms.com/doc/xicclu.html#p1> xicclu <http://www.argyllcms.com/doc/xicclu.html> -g<http://www.argyllcms.com/doc/xicclu.html#g> -kp <http://www.argyllcms.com/doc/xicclu.html#k>0 0 .93 .87 0.65<http://www.argyllcms.com/doc/xicclu.html#k> -l290 <http://www.argyllcms.com/doc/xicclu.html#l> -fif<http://www.argyllcms.com/doc/xicclu.html#f> -ir <http://www.argyllcms.com/doc/xicclu.html#i> PrinterBt.icm<http://www.argyllcms.com/doc/xicclu.html#p1> When calling xicclu this way, I don't want the new window xicclu creates. I just want to dump the input/output CMYK values so I can draw the plot in my own window. How can I do this?
