MagickColorizeImage PixelWands

[ReachingFarr]

I was wondering if anyone could explain what values I should set in the Pixel Wands I am passing to MagicColorizeImage. Right now, with the values I'm setting nothing appears to be happening.

Thanks.

Here's a code snippet to tint an image red:

Code: Select all

  magick_wand = NewMagickWand();
  MagickReadImage(magick_wand, "logo:");
  colorize = NewPixelWand();
  opacity = NewPixelWand();
  PixelSetColor(colorize,"red");
  PixelSetColor(opacity,"#222");
  MagickColorizeImage(magick_wand,colorize,opacity);
  MagickWriteImage(magick_wand,"logo.png");

Sorry for bumping old thread, but why is opacity actually set by color and not by PixelSetAlpha/PixelSetOpacity?

I suppose you are referring to "MagickColorizeImage(magick_wand,colorize,opacity);" The "opacity" there is an argument to the function. It refers to the degree of the effect, not the opacity of the final pixels. See also http://www.imagemagick.org/script/comma ... p#colorize
