gif2bgi(1)						      General Commands Manual							gif2bgi(1)

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.

NAME

       gifclip	-  A  program to clip images in GIF files.  Only one image in a GIF file can be modified at a time.  Neither the image position on
       screen nor the screen size is modified (use <a href="gifpos.html">gifpos

USAGE

       gifclip [-q] [-i Xmin Ymin Xmax Ymax] [-n n Xmin Ymin Xmax Ymax] [-c] [-h] gif-file

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

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

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

       [-i Xmin Ymin Xmax Ymax]

	       Clip first image to the dimensions as specified by the 4 coordinates (Xmin Ymin Xmax Ymax) of a box clipping region.

	      For example: '-i 11 22 33 44' will crop the box from top left [11,22] to bottom right [33,44] out of the first image.

	      If the first parameter is bigger than third one (Xmin > Xmax) they are swapped.  Same for Y.

	      The dimensions of the clipped image must be confined to original image width and height.	Note the clipped image includes  both  the
	      min & max boundary; an image of width W can have coordinates 0 to W-1 (zero based).

	      Only one of -i or -n can be specified.

       [-n n Xmin Ymin Xmax Ymax]

	       Same  as  -i above but for the nth image: `-n 1 11 22 33 44' is exactly the same as the example in -i.  Only one of -i or -n can be
	      specified.

       [-c]

	       Complement.  This removes horizontal and/or vertical bands of the image. For example `-c -i 638 3 658 13' would remove a horizontal
	      band 11 pixels deep beginning at raster line 3, and a vertical band 21 pixels right beginning at pixel 658.

       [-h]

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

	      Note: all coordinates are 0-based --- the top left corner is (0, 0).
