Member Function Documentation

bool cairo_png_trgt::set_rend_desc ( synfig::RendDesc d)

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.

dan RendDesc pointer.
true on success

Reimplemented from synfig::Target.

References synfig::Target::desc, synfig::RendDesc::get_frame_end(), and synfig::RendDesc::get_frame_start().

bool cairo_png_trgt::obtain_surface ( cairo_surface_t *&  )

Obtain a surface pointer based on the render method this function has to be overrrided by the derived targets to create the proper Cairo backend surface for each target type.

Implements synfig::Target_Cairo.

References synfig::Target::desc, synfig::error(), synfig::RendDesc::get_h(), and synfig::RendDesc::get_w().
