GetBufferedPaintBits function

Applies to: desktop apps only

Retrieves a pointer to the buffer bitmap if the buffer is a device-independent bitmap (DIB).

Syntax

Copy

HRESULT GetBufferedPaintBits(
  HPAINTBUFFER hBufferedPaint,
  __out  RGBQUAD **ppbBuffer,
  __out  int *pcxRow
);

Parameters

hBufferedPaint

Type: HPAINTBUFFER

The handle of the buffered paint context, obtained through BeginBufferedPaint.

ppbBuffer [out]

Type: RGBQUAD**

When this function returns, contains a pointer to the address of the buffer bitmap pixels.

pcxRow [out]

Type: int*

When this function returns, contains a pointer to the width, in pixels, of the buffer bitmap. This value is not necessarily equal to the buffer width. It may be larger.

Return value

Type: HRESULT

Returns S_OK if successful, or an error value otherwise. If an error occurs, ppbBuffer is set to NULL and pcxRow is set to zero.

Remarks

The number of bits per pixel depends on the pixel format passed to BeginBufferedPaint.
