A new tutorial video is now available on Patreon. In this lesson, we
will learn how to create double-state icons under Icaros Desktop 2.2.4
using just three tools: the RNO Effects program, the AROS shell, and a
few commands in the right sequence. This tutorial explains how to apply specific graphic effects to a whole iconset through RNO's batch converter, and then how to compose dual-state PNG icons combining the result with original images. Improvements can be added with LunaPaint or ZunePaint, but this is not covered by the tutorial. 
The video is accessible by patrons only. A pledge of $5 (or more, if you like) is required to unlock this content. Patrons will also be able to download the video in MP4 format, if they need to do that for compatibility reasons.
