Comments

This function will save the recognition result of this L_OcrPage as SVG. Normally, the L_OcrDocument_Save must be used to save a page (or more) to an output format. For SVG format, use this function to quickly save the page and create the output document without having to create an OCR document handle first.

This function works whether the page is part of an OCR document or is standalone.

To quickly save a givin page as an SVG stream, call L_OcrPage_SaveSvgMemory.
