#include "l_bitmap.h"

L_LTFIL_API L_INT EXT_FUNCTION L_LoadSvg(pszFile, pOptions, pLoadOptions)

Loads a page from an image, document or vector file as an SVG file.

Parameters

L_TCHAR* pszFile

Character string containing the name of the file to load.

pLOADSVGOPTIONS pOptions

Pointer to a structure that contains the options used for loading SVG files. This can be NULL to use the default options.

pLOADFILEOPTION pLoadOptions

Pointer to optional extended load options. Pass NULL to use the default load options.

Returns

Comments

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

Before calling this function, it may be necessary to get or set file information, such as the page number of a multipage file or the resolution of a PCD file. Refer to Getting and Setting File Information.

Use this function to load a page from any supported image, document, or vector format as SVG (Scalable Vector Graphics). All of the following conditions must be met in order for L_LoadSvg to load a page from a file as SVG:

To find out whether an input file can be loaded as SVG, call L_CanLoadSvg or L_CanLoadSvg2.

The SVG loaded by this function will be returned in the LOADSVGOPTIONS structure.

Be sure to check the resulting SVG document for flatness and perform any necessary operations before continuing.

For more information, refer to Working With SVG.

Note: More options are available in the LOADFILEOPTION structure.
