Member Function Documentation

◆ createSystemMemorySurface()

virtual sal::systools::COMReference< surface_type > dxcanvas::IDXRenderModule::createSystemMemorySurface ( const ::basegfx::B2IVector rSize)
pure virtual

◆ disposing()

virtual void dxcanvas::IDXRenderModule::disposing ( )
pure virtual

◆ flip()

virtual bool dxcanvas::IDXRenderModule::flip ( const ::basegfx::B2IRectangle rUpdateArea,
const ::basegfx::B2IRectangle rCurrWindowArea 
pure virtual

Flip front- and backbuffer, update only given area.

Note: Both update area and offset are ignored for fullscreen canvas, that uses page flipping (cannot, by definition, do anything else there except displaying the full backbuffer instead of the front buffer)

rUpdateAreaArea to copy from backbuffer to front
rCurrWindowAreaCurrent area of VCL window (coordinates relative to VCL HWND)

◆ getHWND()

virtual HWND dxcanvas::IDXRenderModule::getHWND ( ) const
pure virtual

◆ resize()

virtual void dxcanvas::IDXRenderModule::resize ( const ::basegfx::B2IRange rect)
pure virtual

Resize backbuffer area for this render module.

◆ screenShot()

virtual void dxcanvas::IDXRenderModule::screenShot ( )
pure virtual

Write a snapshot of the screen to disk.
