| bool a2dWalker_FilterCanvasObjects::Start | ( | a2dCanvasObject * | object | ) |
start iteration here returns m_result, which value depends on derived class, and defaults to false.
Reimplemented in a2dWalker_MakeTree, a2dWalker_RemoveHierarchy, a2dWalker_LayerGroup, a2dWalker_DetectSmall, a2dWalker_DetectSmallSegments, a2dWalker_AllowedObjects, and a2dBooleanWalkerHandler.

convert canvasobject to a list of polygons. But only for simple primitive objects. first a2dCanvasObject::GetAsCanvasVpaths() is used to convert to vector paths, and next the vector path is translated into polygons.
