Bitmap graphic
Representation of a document as an image file in digital form.
For black and white images, each bit represents one unit of information. Logical 1 represents black and logical 0 represents white (bitonal). This allocation originates in printing where 1 = true = print black. Other allocations also exist.
Gray-level and color information are represented in the same way, whereby the gray or color value of a pixel is defined by several bitmaps.
