grafx21

Usage

Overview

This manual page documents briefly the grafx2 command.

grafx2 is a bitmap paint program that allows you to draw in more than 60 video resolutions, including most of the standard Amiga resolutions : 320x200, 320x256, 320x512, 640x256, 640x512, etc... provided your videocard knows how to handle them.

This program is dedicated to everybody who knows what a single pixel is. Its layout is not very different from the famous Deluxe Paint or Brilliance, so it will be quite easy to handle it if you know at least one of these programs. If you aren't used to the art of drawing with up to 256 colors, it will be a little more difficult for you, but you should give it a try (or more, because most of the power of this program won't show up on the first try).

Environment
