pur_red.pdf pur_red Created attachment 113558 [details] [review] This patch solves it The reason is that the color components of a DeviceN colorspace can't be just copied to the splash bitmap, even not in CMYK or DeviceN splash bitmap. The color must always be converted. This patch solves it. Created attachment 113559 [details]
red square is shown red again
Here the result of
./utils/pdftoppm -png -cropbox -overprint pur_red.pdf pur_red_patch
