Re: Best way to render text on CMYK background?

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 ...

Re: Best way to render text on CMYK background?

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 sa...

Re: Best way to render text on CMYK background?

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&qu...

Best way to render text on CMYK background? [SOLVED]

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 us...

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.

Re: Composite: Differences in defaults/transparency between v6 and v7?

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 pr...

Composite: Differences in defaults/transparency between v6 and v7? [Solved]

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 3x2Si...
