## 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 be set to the same value via `-s`. Defaults of 512 are assumed for unspecified dimensions.

The `-a` flag indicates autosizing (off by default).
