This ansible role installs pngnq, an optimizer for PNG (Portable Network Graphics) files. It can be run from a commandline in an MSDOS window, or from a UNIX or LINUX commandline.

Its main purpose is to reduce the size of the PNG IDAT datastream by trying various compression levels and PNG filter methods. It also can be used to remove unwanted ancillary chunks, or to add certain chunks including gAMA, tRNS, iCCP, and textual chunks.

- hosts: all
  roles:
     - wtanaka.pngnq

Default: True

When True, this role short-circuits itself if a pngnq is already in the PATH.

The full set of configuration options available are visible in defaults/main.yml
