BMP Formats

LEADTOOLS reads and writes the following BMP formats:

Windows Bitmap (BMP). This is a file format created by Microsoft. Some BMP images are compressed with an RLE-type compression.
OS/2 Bitmap (OS/2 BMP). These are files created on an OS/2 operating system. LEADTOOLS supports both 1.x and 2.x formats.
- You can read and write the following bits per pixel, without RLE compression: 1, 4, 8,16, and 24.
- You can read (but not write) the following bits per pixel, with RLE compression: 4, 8 and 16.

File constants associated with these file formats are:
