bool gif::set_rend_desc ( synfig::RendDesc d  )  [virtual]

Sets the RendDesc for the Target to desc.

If there are any parts of desc that the render target is not capable of doing, the render target will adjust desc to fit its needs.

Reimplemented from synfig::Target.

bool gif::init (  )  [virtual]

bool gif::start_frame ( synfig::ProgressCallback cb  )  [virtual]

Marks the start of a frame.

Returns:
true on success, false upon an error.

void gif::end_frame (  )  [virtual]

synfig::Color * gif::start_scanline ( int  scanline  )  [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()

Implements synfig::Target_Scanline.

bool gif::end_scanline ( void   )  [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 supposed to do with it.

Returns:
true on success, false on failure.
