       gif2epsn - A program to dump images saved as GIF files on Epson type printers.


       gif2epsn [-q] [-d dither] [-t bw] [-m map] [-i] [-n] [-p printer] [-h] gif-file

       If no gif-file is given, Gif2Epsn will try to read a GIF file from stdin.





               Quiet  mode.   Default  off  on MSDOS, on under UNIX. Controls printout of running
              scan lines. Use -q- to invert.

       [-d dither]

               Sets size of dithering matrix, where DitherSize can be 2,3 or 4 only (for 2x2, 3x3
              and  4x4  dithering matrices).  Default is 2.  Note image will be displayed in this
              mode only if the mapping option (see -m) selected this mode.

       [-t bw]

               Sets threshold level for B&W mapping in percent.  This threshold level is used  in
              the different mappings as selected via -m.  Default is 19%.

       [-m map]

               Select method to map colors to B&W.  Mapping can be:


              Every  none  background color is considered foreground (white color but is drawn as
              black by printer, unless -i is specified).


              If 0.3 * RED  0.59 * GREEN  0.11 * YELLOW > BW the pixel is considered white color.


              Colors are mapped as in 1, and use dithering of size as defined  using  -d  option.
              BWthreshold is used here as scaler.

              The default is option 0.


               Invert the image, i.e.  black -> white, white -> black.


               Nicer  image.  Uses double-density feature of Epson printer.  This takes more time
              (and kills your ink cartridge faster...) but results are usually better.

       [-p printer]

               Under Unix, output goes to stdout by default; under DOS,  the  default  is  LPT1:.
              With this switch you can specify the output target.


               print one line of command line help, similar to Usage above.


       The output has an aspect ratio of 1, so a square image will be square in hardcopy as well.

       The widest image can be printed is 640 pixels, on 8 inch paper.  You probably will need to
       flip wider images, if height is less than that: `<a href="gifflip.html">gifflip -r x29.gif
       | gif2epsn'.  Wider images will be clipped.
