L_LTSVG_API L_INT L_SvgLoadDocumentMemory(buffer, bufferSize, docHandle, options)
Loads an SVG document from an SVG file from memory.
Pointer to the file in memory to be loaded.
Size of the file in memory (in bytes).
Pointer to the L_SvgNodeHandle referencing the target SVG document.
Optional pointer to a structure containing SVG load options. Pass NULL to use the default options.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
Support for SVG is available in Document and Medical Imaging toolkits.
To get and set information on the document bounds and resolution refer to SVG Size, Bounds and Flat.
When the SVG document data is no longer needed, you must call L_SvgFreeNode to free storage allocated for the SVG document.
Required DLLs and Libraries
Win32, x64, Linux.
This example will save an SVG document to a memory buffer and reload it.
