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:

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
