Hello everyone,

We have added few new features for working with images to the Graphics Mill and released the update. Now you can make color separation as well as merge several CMYK images with alpha channel.
  • New item Format40bppAcmyk of PixelFormat enumeration - specifies that the format is 40 bits per pixel ACMYK; 8 bits each are used for the cyan, magenta, yellow, and black components. Last component is an alpha channel.
  • IChannels.AddAlpha Method - adds an alpha channel to the image. If it already has alpha channel, raises a error.
  • IChannels.Extract Method - extracts channel with given number. It returns grayscale bitmap contains requested channel.
  • IChannels.Replace Method - replaces channel with given number with specified 8-bit grayscale bitmap. It should have the same dimensions as the image itself.
