CPEN391GL

CPEN391 graphics library Please DON'T try some extreme or strange values... This library is not fully tested...

Installing

All source files are in src/ directory, and all header files are in /include directory.

Usage

Simply

#include "CPEN391GL.h"

Supported Features

I will improve these later.

Hardware Accelerated Functions

Draw a single pixel

void write_pixel(int x, int y, int colour)

Draw a horizontal line

void draw_hline(int x1, int y1, int length, int colour)

Draw a vertical line

void draw_vline(int x1, int y1, int length, int colour)

Draw a line between any two points

void draw_line(int x1, int y1, int x2, int y2, int colour)

Functions directly use special hardware graphic acceleration for faster drawing. These functions are faster than drawing pixel by pixel.
Refer to include/HWDraw.h for details.

Triangle

Drawing triangles with specified attributes.
Refer to include/Triangle.h for details.
NOTE: Currently, all three points have to be inside the screen. Border width is not supported neither.

Rectangle

Drawing rectangles with specified attributes. Refer to include/Rectangle.h for details.

Fonts

Displaying texts on screen. Refer to include/Fonts.h for details.

Colours

Some colour constants are defined in include/Colours.h.
Those constants should be used when you want to set any colour in this library. Please refer to include/HWDraw.h: program_palette() if you want to set a special color, or simply change Colours.h.
