Method
RsvgHandleset_size_callback
deprecated: 2.14.
Declaration [src]
void
rsvg_handle_set_size_callback (
  RsvgHandle* handle,
  RsvgSizeFunc size_func,
  gpointer user_data,
  GDestroyNotify user_data_destroy
)
Description [src]
Sets the sizing function for the handle, which can be used to override the
size that librsvg computes for SVG images. The size_func is called from the
following functions:
- rsvg_handle_get_dimensions()
- rsvg_handle_get_dimensions_sub()
- rsvg_handle_get_position_sub()
- rsvg_handle_render_cairo()
- rsvg_handle_render_cairo_sub()
Librsvg computes the size of the SVG being rendered, and passes it to the
size_func, which may then modify these values to set the final size of the
generated image.
Deprecated since: 2.14.
Use rsvg_handle_render_document() instead.
This function was deprecated because when the size_func is used, it makes it
unclear when the librsvg functions which call the size_func will use the
size computed originally, or the callback-specified size, or whether it
refers to the whole SVG or to just a sub-element of it.  It is easier, and
unambiguous, to use code similar to the example above.
Parameters
- size_func
- 
            Type: RsvgSizeFuncA sizing function, or NULL.The argument can be NULL.
- user_data
- 
            Type: gpointerUser data to pass to size_func, orNULL.The argument can be NULL.The data is owned by the caller of the method. 
- user_data_destroy
- 
            Type: GDestroyNotifyFunction to be called to destroy the data passed in user_data, orNULL.
