Member Function Documentation

bool synfig::Target_Scanline::render (  ProgressCallback *  cb = NULL  )  [virtual]

Renders the canvas to the target. Implements synfig::Target.

virtual bool synfig::Target_Scanline::start_frame (  ProgressCallback *  cb = NULL  )  [pure virtual]

Marks the start of a frame. Returns: true on success, false upon an error. See also: end_frame(), start_scanline() Implemented in synfig::Target_Multi, and synfig::Target_Null.

int Target_Scanline::next_frame (  Time &  time  )  [virtual]

virtual void synfig::Target_Scanline::end_frame (   )  [pure virtual]

Marks the end of a frame. See also: start_frame() Implemented in synfig::Target_Multi, and synfig::Target_Null.

virtual Color* synfig::Target_Scanline::start_scanline (  int  scanline  )  [pure virtual]

Marks the start of a scanline. Parameters: scanline  Which scanline is going to be rendered. Returns: The address where the target wants the scanline to be written. Warning: Must be called after start_frame() See also: end_scanline(), start_frame() Implemented in synfig::Target_Multi, and synfig::Target_Null.

virtual bool synfig::Target_Scanline::end_scanline (   )  [pure virtual]

Marks the end of a scanline. Takes the data that was put at the address returned to by start_scanline() and does whatever it is supose to do with it. Returns: true on success, false on failure. See also: start_scanline() Implemented in synfig::Target_Multi, and synfig::Target_Null.

void synfig::Target_Scanline::set_threads (  int  x  )  [inline]

int synfig::Target_Scanline::get_threads (   )  const [inline]

bool Target_Scanline::add_frame (  const synfig::Surface *  surface  )

Reimplemented in synfig::Target_Multi.
