EMPTY-PAGE(1) ExactImage Manual EMPTY-PAGE(1) NAME
empty-page - empty page detector of the ExactImage toolkit SYNOPSIS
empty-page [option...] {-i | --input} input-file empty-page {-h | --help} DESCRIPTION
ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit depths natively, resulting in low memory and computational requirements. empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can be removed from the image processing stream. OPTIONS
-i file, --input file Read image from the specified file. -m n, --margin n Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16. -p x, --percentage x Set fraction of permissible dark pixels. The default is 0.05 (5%). -h, --help Display help text and exit. EXAMPLES
$ empty-page -i test.tif The image has 75461 dark pixels from a total of 1060992 (7.11231%). non-empty EXIT STATUS
The exit status is 0 if the image is mostly white, 1 otherwise. SEE ALSO

PNGPHOON(1) General Commands Manual PNGPHOON(1) NAME
pngphoon -- Creates a png file with the current phase of the moon SYNOPSIS
pngphoon [-w width] [-h height] [-f filename] [-x moons_in_x] [-y moons_in_y] [-s density] [-b] DESCRIPTION
This manual page documents briefly the pngphoon command. This manual page was written for the Debian distribution because the original program does not have a manual page. pngphoon is a program that creates a PNG image of the current phase of the moon. It is a successor to xphoon but does not write to the root window, but to a file. You can use it with window managers that accept commands for their background image settings. It is pronounced "pingphoon" (like "typhoon"). OPTIONS
This program takes the following options. -h Mandatory. Gives the image height. The image must be at least 760px high to be able to contain the moon. If the image is smaller only the stars will be plotted. -w Mandatory. Gives the image width. The image must be at least 760px wide to be able to contain the moon. If the image is smaller only the stars will be plotted. -f Mandatory. File name the PNG image shall be written to, for output to stdout use - instead of a filename -x Number of moons in x axis (for multihead configurations) -y Number of moons in y axis (for multihead configurations) -s Star density -b Black (no earthlight) AUTHOR
