Manual Page Viewer
Section: Using Gnuplot
Using the PostScript text in PS-DATA, create a GIF image suitable for display from a Web page.
If FILENAME=FOO.GIF is specified, then the GIF image will be written to "foo.gif", and the function returns "true" if successful.
If VARNAME=GIF-VAR is specified, then the GIF image will be placed into the binary variable "GIF-VAR", and the function returns "true" if successful.
If neither FILENAME nor VARNAME is specified, the function writes the raw data of the GIF image as an HTML document to the standard output, and closes the standard output stream. This is to facilitate the creation of Web pages which produce GIF images as output.
