-depth does NOT mean image bit depth. It means channel bit depth.

The option will be called 'bmp3:alpha' and will be included in the next release of ImageMagick (6.9.2-7). Below are some examples:

Code: Select all

convert logo: -opaque white -define bmp3:alpha=on bmp3:logo.bmp
convert logo: -opaque white -define bmp3:alpha=true bmp3:logo.bmp
.NET + ImageMagick = Magick.NET https://github.com/dlemstra/Magick.NET, @MagickNET, Donate
