Lotus Manuscript graphics
Lotus Manuscript was a word processor for DOS. It apparently had native .BIT and .RLE raster graphics formats.
This section is based on educated guesswork, from observing the behavior of ART2WP and TGL+.
Files have a 9-byte header. Byte order is little-endian.
Offset Size Description ------ ---- ----------- 0 1 ASCII 'B' for BIT format, 'R' for RLE 1 2 Dots per inch (don't know if x or y) 3 2 Dots per inch 5 2 Height in pixels 7 2 Width in bytes. Multiply by 8 to get width in pixels. 9 var. Image data
RLE image data uses a simple pixel-oriented format. Each byte encodes a run of white or black pixels. The high bit is the color. The low 7 bits are the number of pixels, with an encoded value of 0 meaning 128.
- The Graphics Link Plus v2.00a - DOS utility that can read and write BIT format
- ART2WP v1.7 - DOS utility that can write BIT and RLE formats
- ART2WP v2.1 (RLE support seems broken in this version)
- PixEdit/PixView - Commercial software that claims to read .BIT format
