pointer to svg data
TRUE on success, or FALSE on error.
Deprecated: Use rsvg.handle.Handle.readStreamSync or the constructor functions rsvg.handle.Handle.newFromGfileSync or rsvg.handle.Handle.newFromStreamSync. This function is deprecated because it will accumulate data from the buf in memory until rsvg.handle.Handle.close gets called. To avoid a big temporary buffer, use the suggested functions, which take a gio.file.File or a gio.input_stream.InputStream and do not require a temporary buffer.
Loads the next count bytes of the image. You can call this function multiple times until the whole document is consumed; then you must call rsvg.handle.Handle.close to actually parse the document.
Before calling this function for the first time, you may need to call rsvg.handle.Handle.setBaseUri or rsvg.handle.Handle.setBaseGfile to set the "base file" for resolving references to external resources. SVG elements like <image> which reference external resources will be resolved relative to the location you specify with those functions.
