Member Function Documentation

bool cairo_png_mptr::get_frame ( cairo_surface_t *&  csurface, const synfig::RendDesc &  renddesc, synfig::Time  time, synfig::ProgressCallback *  callback  )

virtual

Gets a frame and puts it into cairo_surface_t.

Parameters

surface	Reference to surface to put frame into
time	For animated importers, determines which frame to get. For static importers, this parameter is unused.
callback	Pointer to callback class for progress, errors, etc.

Returns

true on success, false on error
