Convert gem to bmp

What is the difference between .gem and .bmp?

Description: The GEM (Graphical Environment Manager) Paint file type, with the extension .gem, originates from Digital Research's Graphical Environment Manager, which was an early graphical user interface for computers. These files are specifically used to store bitmap images created or manipulated within the GEM Paint application. GEM Paint provided users with basic tools for creating and editing images, much like early versions of Microsoft Paint. The .gem file format is primarily associated with the GEM desktop environment that was popular in the mid-1980s for PCs running CP/M and later on the Atari ST series of computers.; A BMP file is an uncompressed raster image comprised of a rectangular grid of pixels. It contains a file header (bitmap identifier, file size, width, height, color options, and bitmap data starting point) and bitmap pixels, each with a different color.
