It seems that setting BackgroundColor to Transparent is the critical piece. I actually have that in my current code, so I tried it at some point. I ran so many tests I guess I wasn't doing a good enough job of controlling/tracking changes and thought the background was still collapsing to white. So ...

Converting a 1x1 image to get the color would work fine. As for reading a caption to RGB and converting to CMYK, that gets back to the first problem I posted in the very first code box. When I do this I lose the transparency - the background turns to white. I can reinstate it as shown in the code ...

I was just testing with a created image as in the boiled-down sample below. var mi = new MagickImage(MagickColor.Transparent, 500, 500); mi.ColorSpace = ColorSpace.CMYK; mi.Format = MagickFormat.Tiff; MagickColor blue = ColorCMYK.FromMagickColor(new MagickColor(Color.Blue)); mi.Font = "Arial"; mi ...

I am investigating adding customizable text to our application in which users compose selected items over a selected background. All of the source images are CMYK. IM won't draw text on CMYK images, so I am first drawing the text onto a temporary RGB image and then converting the colorspace. I am ...

Excellent! Thanks for looking into it. We are just starting on this project so I have plenty of time to wait for the next release.

Okay, it definitely seems to have something to do with the TIF format of the overlay image, perhaps the fact that it is CMYK. I broke the test down a bit more and discovered that any manipulation of the price image causes it to lose the anti-aliasing/transparency. In this zip file is the original ...

I am developing an application that composes multiple images over a background. The images are supplied to me and are CMYK 8/1-bit TIFFs. I am generating two test images using the following commands: set path=d:\programs\ImageMagick-6.9.0-4 composite "Can 3x2Sign Price.tif" "Can 3x2Sign.tif ...
