L_LTSVG_API L_INT L_SvgSetBounds(flatDocHandle, bounds)

L_SvgNodeHandle flatDocHandle;	SVG document handle
const L_SvgBounds* bounds;	pointer to a structure

Sets the physical (pixel) bounds of the specified SVG document manually.

Parameter	Description
flatDocHandle	The SVG document handle for which the bounds should be updated.
bounds	Pointer to a structure containing the bounds to use.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

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

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 gets and sets the physical (pixel) bounds and resolution of the document

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName

   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;
