grafx2 - Ultimate 256-color bitmap paint program
grafx2 [options] files...
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).
A summary of options is included below. They can be prefixed by either / - or -- -?, -h, -help Show summary of options. -wide To emulate a video mode with wide pixels (2 x 1). -tall To emulate a video mode with tall pixels (1 x 2). -double To emulate a video mode with double pixels (2 x 2). -wide2 To emulate a video mode with double wide pixels (4 x 2). -tall2 To emulate a video mode with double tall pixels (2 x 4). -triple To emulate a video mode with triple pixels (3 x 3). -quadruple To emulate a video mode with quadruple pixels (4 x 4). -rgb <n> To reduce RGB precision from 256 to n levels. -skin <filename> Use an alternate file for the menu graphics. -mode <videomode> To set a video mode listed with the -help parameter.
User settings are stored in ~/.grafx2/gfx2.ini. This file is really meant to be edited by the user and allows to tweak many aspects of the program.
Since grafx2 uses the SDL library for graphics and user input you can use control some of that parts using the SDL environment variables described at http://www.libsdl.org/cgi/docwiki.cgi/Environment_variables
