Contents:

Types: CreateHBITMAP, CreateFromHBITMAP, SetColor, SmoothBits, SetAlphaFromBrightness, CreateFromFileName, CreateFromFileAndAlphaNames, SetPaletteFromString, CompareBitmaps, MSE2PSNR, PSNR2MSE

Functions:

HBITMAP geBitmapUtil_CreateHBITMAP(geBitmap* Bitmap, HWND window, int mip);

// use DeleteObject when done

Return to Contents

geBitmap* geBitmapUtil_CreateFromHBITMAP(HWND window, HBITMAP hbm);

Return to Contents

geBoolean geBitmapUtil_SetColor(geBitmap* Bmp, int R, int G, int B, int A);

// sets all of the bitmap to one color
// on palettized, use R=G=B=A= 0 to set all palette indeces to zero

geBoolean geBitmapUtil_SmoothBits(geBitmap_Info* pInfo,void* FmBits,void* ToBits, int radius, geBoolean wrap);

// a convolution filter for linear smoothing
// assembly & fast
// Fm == To is ok
// (btw wrap is slow & not in assembly yet)

Return to Contents

geBoolean geBitmapUtil_SetPaletteFromString(geBitmap* Bitmap,char** pParams);
