NAME

pixhalve - halve a color pix file

CONTENTS

SYNOPSIS

pixhalve [-a] [-s squareinsize] [-w in_width] [-n in_height] [-h] [infile.pix] > outfile.pix

DESCRIPTION

Pixhalve will take a color pix(5) format file of given dimensions and reduce the resolution of the file by one half in each direction using a 5x5 pyramid filter. If a file name is not given, standard input will be used. The -w and -n flags specify the input file width and number of scan lines in pixels. They can both be set to the same value via -s. Defaults of 512 are assumed for unspecified dimensions.

The -h flag indicates the input file is high resolution (1024x1024).
