| SoFCOffscreenRenderer::SoFCOffscreenRenderer | ( | const SbViewportRegion & | viewportregion | ) | [protected] |
Constructor.
Argument is the viewportregion we should use when rendering. An internal SoGLRenderAction will be constructed.
Definition at line 63 of file SoFCOffscreenRenderer.cpp.
| SoFCOffscreenRenderer::SoFCOffscreenRenderer | ( | SoGLRenderAction * | action | ) | [protected] |
Constructor.
Argument is the action we should apply to the scene graph when rendering the scene. Information about the viewport is extracted from the action.

The SoOffscreenRenderer base class seems to have a huge memory leak.
Whenever an instance is created internal memory doesn't get freed when destroying it. Thus, SoFCOffscreenRenderer is implemented as singleton to allow to create only one global instance. So, the memory is leaking for this instance only.

| ) | const |
Saves the buffer to filename, in the filetype specified by filetypeextensions.
Note that you must still specify the full filename for the first argument, i.e. the second argument will not automatically be attached to the filename -- it is only used to decide the filetype.
This does basically the same as writeToFile() unless that all QImage file formats are supported if not directly supported by Coin3D.
