NAME

Primitives Demonstration and Testing

DESCRIPTION

This script demonstrates the capabilities of the Graphics::Framebuffer module

SYNOPSIS

 perl primitives.pl [--dev=device number] [--x=X emulated resolution] [--y=Y emulated resolution] [--pixel=pixel size] [--noaccel]

    Examples:

     perl primitives.pl

 perl primitives.pl --dev=1 --x=640 --y=480

 perl primitives.pl --x=1280 --y=720 --pixel=2

 perl primitives.pl --small

OPTIONS

--dev=device number

By default, it uses "/dev/fb0", but you can tell it to use any framebuffer device number. Only the number 0 - 31 is needed here.

--x=width

This tells the script to tell the Graphics::Framebuffer module to simulate a device of a specific width. It will center it on the screen.

 "--x=800" would set the width to 800 pixels.
--y=height

This tells the script to tell the Graphics::Framebuffer module to simulate a device of a specific height. It will center it on the screen.

 "--y=480" would set the height to 480 pixels.
--small

This is a shortcut (and diagnostic tool) to set "x" and "y" to 320x200 respectively. Use this if you are getting bus errors. See the "TROUBLESHOOTING" file for using this setting to determine if GFB is incorrectly detecting screen parameters.

--pixel=pixel size

This tells the module to draw with larger pixels (larger means slower)

--noaccel

Turns off C acceleration. Uses only the Perl routines.

--delay=seconds

Changes the amount of time given to each function

--func="function name"

Instead of running all functions, just run one or more (separated by commas)

NOTES

Any benchmarking numbers are written to STDERR. Animations have benchmarking.

Place any other animated GIFs in the "examples/images/" directory and it will include it in the testing
