2. Basics of Image Processing / 2.2 Picture Types

### 2.2.2 The Bitmap (Monochrome Image)

The simplest picture type is the bitmap. Every pixel uses only 1 Bit, because the pixel can only be set or cleared. The depth is therefore 1 Bit. PhotoLine uses black for set pixels and white for cleared.

Consequently a bitmap doesn’t use much memory, but offers only limited picture quality.

A bitmap, which is 1024 pixels wide, uses 128 Byte per line. A bitmap with a size 1024 x 1024 consumes therefore 128 Kbytes.
