size_reference | Size of reference in bytes |
int SDLTest_CompareSurfaces | ( | SDL_Surface * | surface, |
SDL_Surface * | referenceSurface, | ||
int | allowable_error | ||
) |
Compares a surface and with reference image data for equality
surface | Surface used in comparison |
referenceSurface | Test Surface used in comparison |
