surfaceFromXBitmap() [1/2]

static SurfaceSharedPtr cairocanvas::surfaceFromXBitmap ( const uno::Reference< rendering::XBitmap > &  xBitmap )

static

surfaceFromXBitmap Create a surface from XBitmap

Parameters

xBitmap	bitmap image that will be used for the surface
bHasAlpha	will be set to true if resulting surface has alpha

This is a helper function for the other surfaceFromXBitmap(). This function tries to create surface from xBitmap by checking if xBitmap is CanvasBitmap or SpriteCanvas.

Returns

created surface or NULL

surfaceFromXBitmap Create a surface from XBitmap

Parameters

xBitmap	bitmap image that will be used for the surface
rDevice	reference to the device into which we want to draw
data	will be filled with alpha data, if xBitmap is alpha/transparent image
bHasAlpha	will be set to true if resulting surface has alpha

This function tries various methods for creating a surface from xBitmap. It also uses the helper function surfaceFromXBitmap( xBitmap, bHasAlpha )

Returns

created surface or NULL
