AfxGetDitheredBitmap

Copies a bitmap, replacing its background with a dithered (checker) pattern.

void AFXAPI AfxGetDitheredBitmap(
   const CBitmap &rSrc,
   CBitmap *pDest,
   COLORREF cr1,
   COLORREF cr2
);

Parameters

rSrc
The source bitmap.
pDest
The destination bitmap.
cr1
One of the two dither colors, typically white.
cr2
The other dither color, typically light gray (COLOR_MENU).

Remarks

The source bitmap is copied to the destination bitmap with a two-color (cr1 and cr2) checkered pattern replacing the source bitmap's background. The background of the source bitmap is defined as its white pixels and all pixels matching the color of the pixel in the upper-left corner of the bitmap.

Example

CBitmap bm;
bm.LoadBitmap(IDB_BITMAP1);
CBitmap bmGray;
AfxGetDitheredBitmap(bm, &bmGray, RGB(255,255,255),
   GetSysColor(COLOR_MENU));
