L_LTSVG_API L_INT L_SvgBeginUpdateDocument(docHandle)

Begins a process that will update the elements (nodes) of an SVG document.

Returns

Comments

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

The user can modify the elements of an SVG document using L_SvgEnumerateElements and updating the nodes elements or attributes.

After modifying the values of an SVG document using, it may be necessary to re-calculate the document flat, render optimization and bounding rectangles (refer to Document and Medical more information). Therefore, it is recommended to call L_SvgBeginUpdateDocument before making any updates to the document and calling L_SvgEndUpdateDocument when done. The engine will check during L_SvgEndUpdateDocument if any internal state values need to be re-calculated and update as necessary.

L_SvgBeginUpdateDocument increments an internal counter and L_SvgEndUpdateDocument decrements it. When the counter reaches 0 again, the document is updated. Therefore, the user can chain calls to L_SvgBeginUpdateDocument/L_SvgEndUpdateDocument pairs and the update will only occur once at the end.
