- 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.
- A DDS file is a raster image saved in the DirectDraw Surface (DDS) container format. It can store compressed and uncompressed pixel formats and is often used for texturing video game unit models. DDS files may also be used to store Windows desktop backgrounds or wallpapers.
