- Description
- An RGBA file is a color bitmap image format created by Silicon Graphics (SGI). It is similar to the .RGB file as it supports color RGB channels with an alpha channel.
- 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.
