CDrawingManager::SetAlphaPixel

Colors a transparent pixel in a bitmap.

static void __stdcall SetAlphaPixel(
   COLORREF* pBits,
   CRect rect,
   int x,
   int y,
   int percent,
   int iShadowSize,
   COLORREF clrBase = (COLORREF)-1,
   BOOL bIsRight = TRUE
);

Parameters

  • [in] pBits
    A pointer to the bit values for the bitmap.

  • [in] rect
    A rectangular area in your application. The drawing manager draws a shadow underneath and to the right of this area.

  • [in] x
    The horizontal coordinate of the pixel to color.

  • [in] y
    The vertical coordinate of the pixel to color.

  • [in] percent
    The percentage of transparency.

  • [in] iShadowSize
    The width and height of the shadow.

  • [in] clrBase
    The color of the shadow.

  • [in] bIsRight
    A Boolean parameter that indicates which pixel to color. See the Remarks section for more information.

Remarks

This method is a helper method that is used by the CDrawingManager::DrawShadow method. We recommend that if you want to draw a shadow, call CDrawingManager::DrawShadow instead.

If bIsRight is set to TRUE, the pixel to color is measured x pixels from the right edge of rect. If it is FALSE, the pixel to color is measured x pixels from the left edge of rect.
