- Description
- A CMX 3 file is a vector drawing exported by CorelDRAW 2017 or later, in a newer binary layout than the classic RIFF-based CMX exchange format.
- 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.
