NAME

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

USAGE

       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.

MEMORY REQUIRED

       Screen.

OPTIONS

       [-q]

               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:

       0

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

       1

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

       2

              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.

       [-i]

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

       [-n]

               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.

       [-h]

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

NOTES

       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.
