mkgradient - a tool for making color gradients

Description

mkgradient is a simple tool for making color gradients. It uses the PNG library.

A compiler and libpng with header files (if you're using Debian Linux, try the libpng*-dev packages).

Usage: ./mkgradient <start color> <end color> <direction> <length> <file>

<start color> and <end color> are the both colors of the gradient in the format rrggbb (like in HTML, but without the '#').
<direction> can be 'h' for a horizontal gradient and 'v' for vertical gradient.
<length> is the length of the gradient in pixels.
<file> is the output file of the gradient.

Example: ./mkgradient 000000 ffffff h 256 out.png
