Group 4 FAX
G4 is a method to compress black and white images without losing quality. It is used for fax machines and as a one of the compression types for the TIFF format. G4 treats a picture as black dots and lines on a white page (less file size will be achieved if there are less black dots and lines).
JPEG-2000 VM Format
This is an image file format that is stored without the use of compression algorithms. It is used in the JPEG 2000 standard. This format is capable of storing only one single component, so it is limited to displaying grayscale tones. If you combine multiple PGX files, then you can make a color image.
