Youresam has released LUA BMPlib for PSP. This is a library for helping Lua script coders to load and use BMP images in their Lua programs with a simple line of code. Currently this version is not optimized, and can be slow. Youresam is trying to optimize this library for a better performance.

About:
* BMPlib allows you to open bmp images in lua

How-to:
Simply copy "bmplib.lua" into your programs folder and put dofile("bmplib.lua") in your program.

I have attached a sample BMP along with a sample program. To run the sample, place this folder in your LuaPlayer/Applications folder.

2.00+ USERS: This is like a normal LuaPlayer app and should work like all luaplayer apps do.

Functions:
Image.bmpload(filename)
Opens the 24-bit BMP file and returns it as an image

Bugs:
It takes luaplayer a long time to draw an image pixel by pixel, so loading bitmaps takes some time.

To-Do:
* Bitmap saving once I learn how to save binary files in lua
* All bitmap bit support (1,4,8,16)
* Optimization: If a row of pixels are the same color, draw all at once instead of individually to save time

Author:
This program was created by "youresam". If you need to contact me, my AIM is youresam1. You may modify the source of bmplib, but I will warn you it is tricky. There is padding in certain places based on certain numbers, instead of RGB its GBR, and the pixels are upside down.
