New Post: Converting mask to color

Hi,

I am unsuccessfully trying to give color to a mask. From the ImageMagick documentation I found there are a few ways to do this. How can I achieve any of the following with Magick.NET?

 convert heart_mask.gif  -background Red -alpha Shape  heart_red.png

or

 convert heart_mask.gif -negate  \
      -background Gold  -channel A  -combine   heart_gold.png

or

 convert heart_mask.gif \( +clone \) -alpha off \
      -compose CopyOpacity  -composite \
      -fill HotPink  -colorize 100%    heart_hotpink.png

Thank you for your time.
