Source / code snippets | | | | |  | an small demonstration to that direct reading of BMP-Files for Textures with ASM-command/XPIA and the commands "GetDIBits" for OpenGL.
The colour "schwarz" becomes transparent drawn.
around the Program To using, must yet 2 pattern-BMP-Files prepares go.
by the good Help in the Forum could I the umsetzen.
by the 2D vorraussetzungen with Opengl can very beautiful Sprites produce and so works.
with the Keys "Q,W,E,S" can a little bit speilen.
These demonstration can eachone for itself new umsetzen and in Own programs pieces of it take.

OGL("rotate",0,0,winkel!+90) set : OGL("rotate",0,0,winkel! )
can also yet The SINUS and COSINUS change at will.

| | | The ASM-code is a bisschen gekürzt with : "jmp wandle".
And so can itself then on the code yet calm with better routines.
If one The DLL takes, can too this reinsetzen :
DEF rgb_umwandlung(2) ! "muster.dll","rgb_umwandlung"
and so Call:
rgb_umwandlung(bildxy#,a&)
