#include "l_bitmap.h"

L_LTSVG_API L_INT L_SvgGetDocumentVersion(docHandle, version)

Parameters

const L_SvgNodeHandle docHandle

The SVG document handle to test.

L_SvgVersion* version

Pointer to a variable to be updated with the version.

< 1	An error occurred. Refer to Return Codes.

Comments

Support for SVG is only available in the Document and Medical Imaging toolkits.

To change the version of the SVG document, use L_SvgSetDocumentVersion.

For more information on flat SVG documents and bounds and resolution, refer to SVG Size, Bounds and Flat.

Example

This example will load a DOC file as SVG, set the SVG document version, and then save the document as an SVG file on disk.
