- Description
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
- Created by Digital Equipment Corporation (DEC), SIXEL is a bitmap image format in an escaped sequence (seen as six pixels high and one pixel wide). You have to convert it into a more accessible format if you don’t have a DEC terminal to view it.
