Also known as the transparency layer. RGB the system used to describe and measure the color of a pixel or palette entry. When all 3 levels are 0, the color is black. Monochrome Bitmaps Also known as two color, black or white and bitmap masks. KiSS does not use monochrome bitmaps.
Monochrome bitmaps consist of on and off dots.
Each dot is either on, or it is off. If a monochrome bitmap does not have a palette, it is assumed that on is white, and off is black, or vise-versa. Monochrome bitmaps have very limited use in the present day. Years ago, you would find monochrome bitmaps everywhere. The original Macintosh used monochrome bitmaps only.
