> I have a program that reads graphic commands from a postscript file and draws a logo on existing PDF pages.
> PDF commands are written using PDPageContentStream which works OK except when I pass colors in CMYK color space - in this case the colors are "off". 
> It appears that setStrokingColor(Color color) and setNonStrokingColor(Color color) set the magenta component wrong, they pass yellow instead. 
> Here is the problematic line. Notice the second argument, it should be colorComponents[1], not colorComponents[2]
> {code}
>   setStrokingColor( colorComponents[0], colorComponents[2], colorComponents[2], colorComponents[3] );
> {code}
> The patch and a unit test are attached.
> Regards,
> Yegor
