I am working in this routine pixel-precise.
It is ripped from microhobby and wos forum.
Modified by me. I need help to complete the paint attributes method, because in asm my routine works fine, baut when I passed t sub It fails.
Here is the code.
Modified 20-June-2010 included colour ripped by wos
Modified 21-June-2010 included attributes in the same sub.
Now are two independent subs methods:
1.-PlotChar(file,column,CharAdr)
PlotCharPaint(file,column,atribute)
2.- PlotChat(file,column,CharAdr,atrib)
Probably, this is the last update for this routine.
Modified 2010-07-09 including fastcall and all asm routines embebed. The on ly problem is because the rets in atributes process make me save three bytes in printer buffer. Also I can not use Ubyte in fastcall because I do not understand how it works.
