COLORREF AlphaBlend	(	COLORREF	sourceColor,
		COLORREF	colorAlpha,
		unsigned char	alpha
	)			`[static]`

Blends two colors with a transparency coefficient.

Parameters:

`[in]`	sourceColor	Specifies the source color
`[in]`	colorAlpha	Specifies the second color
`[in]`	alpha	Transparency coefficient

Returns:: Color after blending

bool AlphaBlend	(	CDC &	dc,
		const CRect &	rect,
		COLORREF	color,
		BYTE	alpha
	)			`[static]`

Displays bitmaps with transparent or semitransparent pixels.

Parameters:

`[in]`	dc	handle to DC
`[in]`	rect	Rectangle in DC to merge with a specified color
`[in]`	color	Color with which the image is merged
`[in]`	alpha	Transparency coefficient

Returns:: True if the image has been successfully merged with the specified color. Otherwise false.

bool Load32BitImage	(	CImageList &	imageList,
		UINT	resourceId,
		bool	useMask,
		COLORREF	maskColor
	)			`[static]`

Helps to load 32-bit color image from resources.

Parameters:

`[in,out]`	imageList	Images list to be loaded from resources
`[in]`	resourceId	Resource identifier
`[in]`	useMask	Value indicating that a color mask should be used
`[in]`	maskColor	The color mask

Returns:: True if the image list has been successfully loaded. Otherwise false.

bool IsAvailable ( ) [static]

Indicates that alpha-blend & gradient services are available.

Returns:: True if available. Otherwise - false.

BOOL GradientFill	(	HDC	hdc,
		PTRIVERTEX	pVertex,
		ULONG	dwNumVertex,
		PVOID	pMesh,
		ULONG	dwNumMesh,

	)			`[static]`

Fills rectangle and triangle structures.

Parameters:

hdc	handle to DC
pVertex	array of vertices
dwNumVertex	number of vertices
pMesh	array of gradients
dwNumMesh	size of gradient array
dwMode	gradient fill mode

BOOL AlphaBlend	(	HDC	hdcDest,
		int	nXOriginDest,
		int	nYOriginDest,
		int	nWidthDest,
		int	nHeightDest,
		HDC	hdcSrc,
		int	nXOriginSrc,
		int	nYOriginSrc,
		int	nWidthSrc,
		int	nHeightSrc,
		BLENDFUNCTION	blendFunction
	)			`[static]`

Displays the bitmaps that have transparent or semitransparent pixels.

Parameters:

nHeightDest	destination height
hdcSrc	handle to source DC
nXOriginSrc	x-coord of upper-left corner
nYOriginSrc	y-coord of upper-left corner
nWidthSrc	source width
nHeightSrc	source height
blendFunction	alpha-blending function

BOOL TransparentBlt	(	HDC	hdcDest,
		int	xDest,
		int	yDest,
		int	nDestWidth,
		int	nDestHeight,
		HDC	hdcSrc,
		int	xSrc,
		int	ySrc,
		int	nSrcWidth,
		int	nSrcHeight,
		UINT	clrTransparent
	)			`[static]`
