PixelSetColor, gradient and DrawSetFillColor problem.

[pinkfish00]

I have a question I hope somebody can help me.
I am using the C API, and I want to simply draw a rounded rectangle with a gradient fill.
Solid fill works great, but when I try to use a gradient, the rectangle is simply black, is this supported at all (I did not find any mention of the word 'gradient' in "pixel-wand.c")?
and if not what is the alternative?

Code: Select all

PixelSetColor(gradient, "gradient:red-blue"); // fails, full black
//PixelSetColor(gradient, "white"); // works, full white
DrawSetFillColor(draw, gradient);
DrawSetStrokeColor(draw, black);
DrawRoundRectangle(draw, 0, 0 ,inWidth-1, inHeight-1, 8, 8);

thank you!

PixelSetColor returns a value of MagickFalse when given 'gradient:red-blue" as an argument.
The only alternative way to do it that I can think of is to create a rectangular gradient image of the appropriate size (using "gradient:red-blue" as an argument to MagickReadImage), create a plain white/black image with the rounded rectangle and use that as the alpha channel. Then composite this over the image. It's messy but should work.

that was my workaround as well, too bad this doesn't work ... thx.
