tgatool.c

simple tool for TGA images

HELLO

I would like to present your attention a simple tool for TGA images.

HOW TO USE?

1. Compile the object module. Like this: gcc -o tgatool.o -c ./tgatool.c
2. Include header file in your code, uses include macro: #include "tgatool.h"
3. Use function from header, whith them usage (more details in tgatool.h);
4. Indicate the object module in parametr list, when you compile your main program: gcc -o program.bin ./main.c ./tgatool.o
5. Fun.

FOR WHAT?

This tool was created for educational purposes. You can use it to study computer graphics. For example, you can create a canvas and draw a line on it using the Bresenham algorithm. Next, you can make a simple parser of .obj wavefront files and draw 3D models.

DEPENDENCIES

• C compiler;
• Standart C library.

LIMITATIONS

• Writing to the color-maped type is not completed but opening color-maped images is allowed;
• Ignoring the byte order. Some pictures may open upside down.
• Everything is ultimately stored in a matrix of int's thus, pictures with a color depth greater than 32 will lose quality.
• Only original TGA format supported, no extension/developer zone.
