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.
