| Member | Type | Description |
|---|---|---|
| bmp | char * | light_map_pic pixels |
| sizex | int | size in x (power of 2) |
| sizey | int | size in y (power of 2) |
| bytesx | int | number of bytes per line (sizex*bytespixel) |
| bytesxy | int | total bytes of the light_map_pic bmp (bytesx*sizey) |
| bytespixel | int | the light map bytes per pixel: 3 - RGB 4 - RGBA |
This class implements the light_map picture used when drawing. This picture can have several light_map pictures in it and many light_map classes will use a single light_map_pic.
