Detailed Description

Base class providing cached re-rendering, if XCanvas returns XCachedPrimitive.

Derive from this class and implement private render() method to perform the actual primitive rendering. Return cached primitive into given reference. Next time this class' public render() method gets called, the cached representation is taken.

Constructor & Destructor Documentation

CachedPrimitiveBase() [1/2]

cppcanvas::internal::CachedPrimitiveBase::CachedPrimitiveBase	(	CanvasSharedPtr	xCanvas,
		bool	bOnlyRedrawWithSameTransform
	)

Constructor.

Parameters

rCanvas	Canvas on which this primitive is to appear
bOnlyRedrawWithSameTransform	When true, this class only reuses the cached primitive, if the overall transformation stays the same. Otherwise, repaints are always performed via the cached primitive.

render() [1/2]

bool cppcanvas::internal::CachedPrimitiveBase::render ( const ::basegfx::B2DHomMatrix &  rTransformation ) const

overridevirtual

Render this action to the associated canvas.

Parameters

rTransformation

Transformation matrix to apply before rendering

Returns

true, if rendering was successful. If rendering failed, false is returned.

Implements cppcanvas::internal::Action.
