You can launch Grafx2 with some command line arguments to open a file directly or get a specific option. Note that on Windows, drag-and-dropping a file on a Grafx2 shortcut will pass the file name as the only command-line argument, so it will start Grafx2 with this file loaded.
- */?* displays help, along with a list of the availables videomodes. Ex:
Syntax: grafx2 [<arguments>] [<picture1>] [<picture2>] <arguments> can be:] -? -h -H -help for this help screen -wide to emulate a video mode with wide pixels (2x1) -tall to emulate a video mode with tall pixels (1x2) -double to emulate a video mode with double pixels (2x2) -wide2 to emulate a video mode with double wide pixels (4x2) -tall2 to emulate a video mode with double tall pixels (2x4) -triple to emulate a video mode with triple pixels (3x3) -quadruple to emulate a video mode with quadruple pixels (4x4) -rgb n to reduce RGB precision from 256 to n levels -skin <filename> to use an alternate file with the menu graphics -mode <videomode> to set a video mode Arguments can be prefixed either by / - or -- They can also be abbreviated. Available video modes: window 320x200 320x240 320x256 320x400 320x480 512x264 512x288 576x240 592x240 608x240 632x264 704x288 736x240 768x240 768x288 784x240 800x288 1280x960 1280x1024 1360x768 1600x900 1600x1024 1600x1200
- */mode 320x200* starts grafx2 in 320x200 fullscreen video mode. All modes are fullscreen except for the special name "window".
- */double* emulates 2x2 pixels, */triple* emulates 3x3 pixels, */quadruple* 4x4 pixels. These are useful when the intended display resolution of your picture (eg for 320x240) is much greater than the actual resolution of the display you are editing it on (eg 1280x960), and/or the GUI of Grafx2 is becoming too small / unreadable.
- */wide* and */tall* allow to use rectangle pixels (horizontal and vertical). This is useful to edit Amstrad CPC pictures, for example.
- */wide2* and */tall2* are doubled versions of /wide and /tall. That is, /wide2 uses 4x2 pixels, and /tall2 uses 2x4 pixels.
- */rgb n* sets the color depth to n. For example, /rgb 2 will give you a spectrum-style 16-colors palette, /rgb 3 will give the Amstrad CPC 27 colors, /rgb 16 will give a classical Amiga palette, and /rgb 64 will give you a VGA palette, like the DOS version of grafx2 had.
- *picture1* and *picture2* are the names of files to open immediately.
For example :
grafx2 /mode 320x200 My_drawing.png
