Function Documentation

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

Create a blend frame as BitmapEx.

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