imgz

A utility to resample images.

Requirements

• vips
  This is a soft requirement. Instead of linking libvips,
  this app uses vips CLI app to resize images. If it's not available in $PATH, it will default to imaging — a pure image processing library written in golang. It uses unfortunately a lot more RAM and CPU than vips.

Flags:
  -h, --help       Show context-sensitive help.
