Comments

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

SVG specifications do not require the use of uniqe IDs for the elements. Unique IDs may be desirable when connecting SVG elements to external data structures or to quickly perfrom search using XML methods such as XPATH.

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

Example

This example loads a PDF file as SVG and then adds IDs to elements

L_INT SvgAddElementIDsExample(L_VOID) 
{ 
   L_INT nRet = ERROR_FILE_FORMAT; 
 
   LOADSVGOPTIONS options; 
   memset(&options, 0, sizeof(LOADSVGOPTIONS)); 
   options.uStructSize = sizeof(LOADSVGOPTIONS); 
   options.uFlags = L_LOADSVGOPTIONS_NONE; 
   options.SvgHandle = NULL; 
 
   /* Load the document as SVG */ 
   L_TCHAR filename[L_MAXPATH] = MAKE_IMAGE_PATH(TEXT("Leadtools.pdf")); 
 
   L_BOOL canLoad = FALSE; 
   nRet = L_CanLoadSvg(filename, &canLoad, NULL); 
   if (canLoad) 
   { 
      nRet = L_LoadSvg(filename, &options, NULL); 
      if (nRet != SUCCESS) 
         return nRet; 
 
      nRet = L_SvgAddElementIDs(options.SvgHandle); 
 
      L_SvgFreeNode(options.SvgHandle); 
   }
