NAME
pammosaicknit - validate a mosaic knitting pattern
SYNOPSIS
pammosaicknit [in_netpbmfile]
DESCRIPTION
This program is part of Netpbm(1).
pammosaicknit helps the user create mosaic knitting patterns
⟨http://en.wikipedia.org/wiki/Slip-stitch_knitting#Mosaic_knitting⟩ .
The program inputs a black-and-white Netpbm image that describes a mo-
saic knitting pattern and outputs a color Netpbm image of the same pat-
tern but with invalid runs shown in red.
A valid knitting pattern starts with a "black" row on the bottom and
alternates "white" and "black" rows. A "black" row can contain any ar-
rangement of black pixels but no more than three consecutive white pix-
els. A "white" row can contain any arrangement of white pixels but no
more than three consecutive black pixels. Columns wrap horizontally, so
a "white" row that both begins and ends with two black pixels is deemed
to contain four consecutive black pixels. Because this is an invalid
number for a "white" row, those four pixels will be recolored red in
the output image.
For clarity, there are two shades of red in the output image. Dark red
pixels indicate pixels that were black in the input image but which
must contain one or more white pixels. Light red pixels indicate pixels
that were white in the input image but which must contain one or more
black pixels.
If the output image contains no red pixels, then the input image repre-
sents a valid mosaic knitting pattern.
OPTIONS
There are no command line options defined specifically for pammosaick-
nit, but it recognizes the options common to all programs based on lib-
netpbm (See
Common Options ⟨index.html#commonoptions⟩ .)
ARGUMENTS
pammosaicknit's only argument, in_netpbmfile, is the name of an image
file that represents a mosaic knitting pattern. If you don't specify
in_netpbmfile, the program reads the image from Standard Input.
NOTES
If the input image is not a black-and-white image, pammosaicknit con-
verts it internally to black and white by thresholding each pixel's lu-
minosity. The output image is always a color image containing at most
four colors (black, white, dark red, light red).
