## Name

pixhalve — halve a color pix file

## 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).
