A variable-sized array of bytes. Uncompressed bitmap data represents a bitmap as a bottom-up, left-to-right series of pixels. Each pixel is a whole number of bytes. Each row contains a multiple of four bytes (including up to three bytes of padding, as necessary). Compressed bitmaps not in 32 bits-per-pixel format are compressed using Interleaved Run-Length Encoding (RLE) and encapsulated in an RLE Compressed Bitmap Stream structure (see section ) while compressed bitmap data at a color depth of 32 bits-per-pixel is compressed using RDP 6.0 Bitmap Compression and stored inside an RDP 6.0 Bitmap Compressed Stream structure (see section in [MS-RDPEGDI]).
