I think you use static_cast rather than C style casts and ass /Qifist as a compiler swich to swich it on. Or use assembly #pragma warning (disable:4035) __declspec( naked ) long Q_ftol( float f ) { static int tmp; __asm fld dword ptr [esp+4] __asm fistp tmp __asm mov eax, tmp __asm ret }

The best graphics library I know of for speed is Fastgraph by Ted Gruber Software, Inc., written in hand-optimized assembly language. The algorithm I originaly designed (in C) used assembly level routines (direct video access via hardware support) to read/write the pixel data, that is where the main bootleneck is. It was not intended to be used for image proccessing, but for simple fills like that used by the paint program that comes with Windows. INTP
