Hi,
Could someone please help me out with displaying a bitmap in only one colour?
Thanks,
Nisha.

What do you mean by one color. Do you mean black and white or you mean only the RGB any one stream.

What I meant was to display in any RGB colour;for instance ,say, red.

Thanks.

Just try out the following.

Use CDC::StretchBlt

BOOL StretchBlt( int x, int y, int nWidth, int nHeight, CDC* pSrcDC, int xSrc, int ySrc, int nSrcWidth, int nSrcHeight, DWORD dwRop );

to get such a combination that you can mask the image bits to display the requested of RGB. and then use CDC::MaskBlt

BOOL MaskBlt( int x, int y, int nWidth, int nHeight, CDC* pSrcDC, int xSrc, int ySrc, CBitmap& maskBitmap, int xMask, int yMask, DWORD dwRop );

to mask the bitmap and display it to user.

Also I forgot to add that

BOOL TransparentBlt(
  HDC hdcDest,
  int nXOriginDest,
  int nYOriginDest,
  int nWidthDest,
  int hHeightDest,
  HDC hdcSrc,
  int nXOriginSrc,
  int nYOriginSrc,
  int nWidthSrc,
  int nHeightSrc,
  UINT crTransparent
);

can also help but its for transparent output.
