NAME

       cacaview - ASCII image browser

SYNOPSIS

       cacaview [FILE...]

DESCRIPTION

       cacaview  is  a lightweight text mode image viewer. It renders images using colour ASCII characters. It is a powerful add-on to famous con-
       sole programs such as the mutt email client, the slrn newsreader and the links or w3m web browsers.

       cacaview can load the most widespread image formats: PNG, JPEG, GIF, PNG, BMP etc.

       You can zoom and scroll the image around for more details, and choose four different dithering modes. All commands are accessible through a
       single key press.

KEYS

       ?      show the help screen

       n, p   switch to next image, previous image

       Left, Right, Up, Down or h, l, k, j
	      scroll the image around

       +, -   zoom in and out

       z      reset the zoom level to normal

       f      switch fullscreen mode (hide/show menu and status bars)

       d      toggle the dithering mode (no dithering, 4x4 ordered dithering, 8x8 ordered dithering and random dithering)

       q      exit the program

EXAMPLE

       cacaview /usr/share/pixmaps/*.*

BUGS

       There  is no support for aspect ratio yet. Also, since there is no way yet to load an image from cacaview it is completely useless when run
       without an argument.

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.
