Summary: RIFF (Raster Image File Format)

--------

Image Studio uses a file format called RIFF (Raster Image File Format).  This
uses a two-dimensional compression based upon CHANGES in gray level between
adjacent (horizontally AND vertically) pixels.  In order to encourage
developers to support this format, Letraset will supply C source code to
read and write RIFF.  If you don't have the code, ask the person who supplied
the image to give you a TIFF format image instead (Image Studio can also
save in TIFF format).
