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.
