Fastgraph Pixel Run Format and Fastgraph Packed Pixel Run Format are raster graphics formats associated with the Fastgraph and Fastgraph/Light graphics toolkits from Ted Gruber Software. In this article, we'll use the abbreviation PRF to refer to the formats.
Contents |
Discussion
The preferred filename extensions seem to be .SPR (probably for Standard Pixel Run) and .PPR, though others are also used.
Though the product is named "Fastgraph", some filenames use the string "FASTGRAF".
PRF is mainly for programmers. The Fastgraph package does include some DOS utilities (SNAPSHOT.EXE, CLIP.EXE, etc.) that use it.
There might be multiple variants of PRF, some of which are more portable than others. (More research needed.)
Identification
Some PRF files begin with (hex) bytes 46 00 41 00 53 00 54 00 47 00 52 00 41 00 46 00
. But others do not.
