Re: Magick++ ColorCMYK
I was a bit quick on that one. I still get transparent color/stroke when I draw on the image and do nothing else. So draw (rgb) on CMYK image will produce transparent color/stroke on any color.

Re: Magick++ ColorCMYK
Found the issue. I'm compositing the drawn image as an "layer" on top of an transparent image (CMYKA) and the composite (Over) seems to add the transparency (on the brush strokes).

Re: Magick++ ColorCMYK
Yeah, I know, but as I said earlier I don't want to do that if possible. Why is drawing anything on CMYK (except for black) transparent? is there something I need to set, or know about? I'm also open to modifying the (IM) source just to get this (no transparency) working. Any pointers to the problem...

Re: Magick++ ColorCMYK
Yeah, that's what I though. But using RGB colors still produces the transparency effect when drawing on CMYK, is there a way to workaround that issue? I would prefer not to convert the image to RGB before drawing and then converting back to CMYK, that will just kill performance (I could of course fi...

Re: Magick++ ColorCMYK
I always use color numbers in IM (so I don't need to reference colors.xml).
My problem is that it seems IM always will draw in RGB, but on an CMYK image the colors are "inverted" and transparent. I can fix the color but not the transparency.

Re: Magick++ ColorCMYK
I setup a brush then draw (DrawLine with strokeColor etc). Works fine on RGB, but not CMYK. (as seen on the image above). I guess ColorCMYK support in Magick++ would fix this? Or are there any workaround for this? image.strokeAntiAlias(...); image.strokeLineCap(...); image.strokeLineJoin(...); image...

Re: Magick++ ColorCMYK
So, I'm able to get the correct(-ish) color by just adding cyan=>red etc, but for some reason the color/brush is transparent.

[SOLVED] Magick++ ColorCMYK
Hi,
Would it be possible to get support for ColorCMYK in Magick++? I need to draw CMYK colors on CMYK image and can't find any CMYK color support in Magick++.
Regards
