Remarks

  • The bits per pixel of the affected image will change according to the value of Type property, or the type parameter of the constructor as follows:
    If the type isBits per pixel will be:
    Thin8 bits per pixel grayscale
    LinkBlackWhite1 bit per pixel
    LinkGray8 bits per pixel grayscale
    LinkColor8 bits per pixel color
    ApproxColor8 bits per pixel color
  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Supportfor 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
