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.
