CopyDrawnTo¶

function CopyDrawnTo(aDest: ISVGBitmap; const aSrceRect: TSVGRect): Boolean;

Copies what has been drawn so far in aSrceRect, in pixels of the context, to the top left of aDest. Works while a scene is open, which is what mix-blend-mode needs to read what is behind an element.

Returns: False when the context has no pixels that can be read: GDI+ on a device context, print pages, EMF.
