Purpose. The SVG parser-instance API: load an SVG once, inspect it, and place it any number of times, instead of re-parsing the file on every pdfInsertSVG call.

Description. pdfLoadSVGA/W parse an SVG file — and pdfLoadSVGFromBuffer an in-memory SVG image — into a document-owned parser instance and return a 1-based handle; each call creates a NEW instance, so the same file can be loaded twice and yield two independent handles. A missing file or unparseable image answers -1. pdfGetSVGSize reports the intrinsic size from the SVG's viewBox/width/height. pdfGetSVGSymbolCount and pdfGetSVGSymbolNameA enumerate the image's named symbol elements (the name call fills Buffer and returns the name length, so a two-call size-then-fetch pattern works). pdfDeleteSVG releases one instance; every instance is released with the document in any case.

Parameters.

Return value. Load calls: a handle >= 1, or -1 on failure. pdfGetSVGSize/pdfDeleteSVG: True/False. pdfGetSVGSymbolCount: the symbol count. pdfGetSVGSymbolNameA: the name length, -1 for a bad handle or index.
