RTF is a cross-platform format for storing labeled text documents, created jointly by Microsoft and Adobe, as meta-tags for the format Word in 1982. Adobe has in 1985 continued to develop the format and created a language PostScript. The basis is a simple text format, control sequences which are not macros that are available for change, and teams with a fixed behavior.
This format is used for storing bitmap images. It supports many different file types and compression algorithms. One Palm bitmap file can contain multiple versions of the same images with different colors. These files are used on PALM devices.
