XCanvas
(referenced interface's summary:)
Central interface for rendering.
Description
This is a specialization of the canvas interface for bitmapped canvases.

This interface is a specialization of the canvas interface for bitmapped canvases, where additional methods for accessing and moving of bitmap content are provided.

Since
OOo 2.0

Methods' Summary
copyRect This method copies a rectangular area from a place of one canvas to a place on another. 
Methods' Details
copyRect
void
copyRect( [in] XBitmapCanvas  sourceCanvas,
[in] ::com::sun::star::geometry::RealRectangle2D  sourceRect,
[in] ViewState  sourceViewState,
[in] RenderState  sourceRenderState,
[in] ::com::sun::star::geometry::RealRectangle2D  destRect,
[in] ViewState  destViewState,
[in] RenderState  destRenderState )
raises( ::com::sun::star::lang::IllegalArgumentException,
VolatileContentDestroyedException );

Description
This method copies a rectangular area from a place of one canvas to a place on another.

This method copies a rectangular area from a place of one canvas to a place on another. Source and destination areas are permitted to overlap. If the source view or render state has a clipping set, the regions clipped away from the source rectangle are regarded fully transparent for the copy operation. The device color for both source and destination render state is ignored, the compositing mode only for the source render state.

Parameter sourceCanvas
Canvas from which to copy the bitmap data. Can be identical to the canvas this method is called on, but must be valid.
Parameter sourceRect
Rectangle from which to copy the bitmap data. This rectangle is subject to both view and render transformation, before being applied. Thus, on screen, it does not necessarily resemble a rectangle any more. The rectangle must be non-empty, see ::com::sun::star::geometry::RealRectangle2D for details.
Parameter sourceViewState
The view state to apply to the source of this copy operation. The view transformation must be non-singular.
Parameter sourceRenderState
The render state to apply to the source of this copy operation. The render transformation must be non-singular, and the compositing mode must be one of the ::CompositingOperation values.
Parameter destRect
Rectangle into which to copy the bitmap data. This rectangle is subject to both view and render transformation, before being applied. Thus, on screen, it does not necessarily resemble a rectangle any more. The rectangle must be non-empty, see ::com::sun::star::geometry::RealRectangle2D for details.
Parameter destViewState
The view state to apply to the destination of this copy operation. The view transformation must be non-singular.
Parameter destRenderState
The render state to apply to the destination of this copy operation. The render transformation must be non-singular, and the compositing mode must be one of the ::CompositingOperation values.
Throws
com::sun::star::lang::IllegalArgumentException if one of the parameters are not within the specified range.
