- Description
- This format is used to compress TIFF images when sending them via fax machines. This format helps reduce the data transmission time. Group 3 eliminates redundant data during compression in order to reduce file size. The standard 10:1 compression ratio may be increased to the user's preferences, but it can lead to a significant loss of image quality.
- 1-bit black and white image; formatted in text format; basic raster image format in which each pixel is represented by a byte that contains a 1 or 0; 1 represents black and 0 represents white pixels.
