> [PATCH] PDPageContentStream incorrectly sets colors in CMYK color space

> Attachments: bug-1469.patch

>
> 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
