Detailed Description

Definition of the surface proxy class.

Surface proxies are the connection between one source image and one or more hardware surfaces (or textures). in a logical structure surface proxies represent solely this dependency plus some simple cache management.

Member Function Documentation

draw() [1/3]

bool canvas::SurfaceProxy::draw ( double  fAlpha, const ::basegfx::B2DPoint &  rPos, const ::basegfx::B2DHomMatrix &  rTransform  )

overridevirtual

Render the surface content to screen.

Parameters

fAlpha	Overall alpha for content
rPos	Output position
rTransform	Output transformation (does not affect output position)

Implements canvas::ISurfaceProxy.

Definition at line 88 of file surfaceproxy.cxx.

References maSurfaceList.

draw() [2/3]

bool canvas::SurfaceProxy::draw ( double  fAlpha, const ::basegfx::B2DPoint &  rPos, const ::basegfx::B2DPolyPolygon &  rClipPoly, const ::basegfx::B2DHomMatrix &  rTransform  )

overridevirtual

Render the surface content to screen.

Parameters

fAlpha	Overall alpha for content
rPos	Output position
rClipPoly	Clip polygon for the surface. The clip polygon is also subject to the output transformation.
rTransform	Output transformation (does not affect output position)

Implements canvas::ISurfaceProxy.

bool canvas::SurfaceProxy::draw ( double  fAlpha, const ::basegfx::B2DPoint &  rPos, const ::basegfx::B2DRange &  rArea, const ::basegfx::B2DHomMatrix &  rTransform  )

overridevirtual

Render the surface content to screen.

Parameters

fAlpha	Overall alpha for content
rPos	Output position
rArea	Subset of the surface to render. Coordinate system are surface area pixel, given area will be clipped to the surface bounds.
rTransform	Output transformation (does not affect output position)

Implements canvas::ISurfaceProxy.
