vdith45(1)

PROGRAM
vdith45 - Perform dithering using ordered (matrix) technique, optimized for 45 degrees.

SYNTAX

vdith45

-i  input image filename

-o  output image filename

[-V]
    Gives the version for vdith45

[-U]
    Gives the usage for vdith45

[-P]
    Prompts for command line options

[-A [file1]]
    Creates the answer file called vdith45.ans or file1

[-a [file1]]
    Uses vdith45.ans or file1 as the answer file

DESCRIPTION
vdith45 performs an 8x8 ordered block dither with major axes lying along the 45 degree diagonals. This dither provides lots of grey levels at the expense of spatial resolution, and is relatively easy on the eyes from a distance.

The output file is of type BIT, suitable for sending to the laser printer using one of the Khoros printing routines.

REQUIRED ARGUMENTS

-i  type: infile
    desc: input image filename

-o  type: outfile
    desc: output image filename

OPTIONAL ARGUMENTS
none

EXAMPLES
vdith45 -i ball.xv -o dith45_ball.xv

This will perform the ordered matrix dithering on the input image, and store the result in dith45_ball.xv.
