.SH DESCRIPTION
|
|
Those functions are meant to draw monochrome with fill bits bitmaps -- like game sprites -- on the VRAM.
|
|
|
|
Functions starting with the ML_bmp_8 draw 8*8 bitmaps. Functions starting with ML_bmp_16 draw 16*16 bitmaps. All other images must be drawn with the the other functions.
|
|
|
|
Function with the _cl suffix are functions using clipping, which means they are able to draw sprites even if they aren't completely on screen. Other functions only draw the bitmap if it is in the screen -- which makes them a little faster.
