draw()

bool cppcanvas::internal::ImplRenderer::draw ( ) const

overridevirtual

Render to parent canvas.

This method renders the content to the parent canvas, i.e. the canvas this object was constructed for.

Returns

whether the rendering finished successfully.

drawSubset()

bool cppcanvas::internal::ImplRenderer::drawSubset ( sal_Int32  nStartIndex, sal_Int32  nEndIndex  ) const

overridevirtual

Render subset of metafile to given canvas.

This method renders the given subset of the content to the associated canvas.

Parameters

nStartIndex	The index of the first action to be rendered (the indices correspond roughly to the action indices of the originating GDIMetaFile. Note, although, that certain actions, e.g. text, accounts for more than one index: a text produces as many addressable indices as it has characters).
nEndIndex	The index of the first action not painted anymore, i.e. the action after the last action rendered (the indices correspond roughly to the action indices of the originating GDIMetaFile. Note, although, that certain actions, e.g. text, accounts for more than one index: a text produces as many addressable indices as it has characters).

Returns

whether the rendering finished successfully.

getSubsetArea()

basegfx::B2DRange cppcanvas::internal::ImplRenderer::getSubsetArea ( sal_Int32  nStartIndex, sal_Int32  nEndIndex  ) const

overridevirtual

Query bounding box of metafile subset.

This method queries the actual bounding box of the given subset, when rendered on the associated canvas.

Parameters

nStartIndex	The index of the first action to be rendered (the indices correspond roughly to the action indices of the originating GDIMetaFile. Note, although, that certain actions, e.g. text, accounts for more than one index: a text produces as many addressable indices as it has characters).
nEndIndex	The index of the first action not painted anymore, i.e. the action after the last action rendered (the indices correspond roughly to the action indices of the originating GDIMetaFile. Note, although, that certain actions, e.g. text, accounts for more than one index: a text produces as many addressable indices as it has characters).

Returns
