Function Documentation

createBlendFrame() [1/2]

BitmapEx createBlendFrame	(	const Size &	rSize,
		sal_uInt8	nAlpha,
		Color	aColorTopLeft,
		Color	aColorBottomRight
	)

Create a blend frame as BitmapEx.

Parameters

nAlpha	The blend value defines how strong the frame will be blended with the existing content, 255 == full coverage, 0 == no frame will be drawn
aColorTopLeft,aColorBottomRight	The colors defining the frame. These colors are linearly interpolated from aColorTopLeft and aColorBottomRight using the width and height of the area
rSize	The size of the frame in pixels
