BOOL CBCGPDrawManager::HighlightRect	(	CRect	rect,
		int	nPercentage = -1,
		COLORREF	clrTransparent = (COLORREF)-1,
		int	nTolerance = 0,
		COLORREF	clrBlend = (COLORREF)-1
	)

Makes a rectangular area highlighted.

Returns

Nonzero if successful; otherwise 0.

Call this member function to highlight a rectangular area. If nPercentage is between 0 and 99 ([0, 99]), the HighlightRect function uses the alpha blending algorithm. If the nPercentage parameter is -1, it uses the default highlight level (e.g., Microsoft Office 2000-style menus highlighting). If nPercentage is 100, it does nothing and returns TRUE.

Parameters

rect	Specifies a rectangular area to fill.
nPercentage	Specifies the transparency percentage.
clrTransparent	Specifies the transparent color.
nTolerance	Color tolerance. Should be within 0-255 range.
clrBlend	Base blending color.
