LFile::ReadFileTransforms

#include "ltwrappr.h"

virtual L_INT LFile::ReadFileTransforms(pTransforms, pLoadFileOption=NULL)

pFILETRANSFORMS pTransforms;	/* pointer to a transform structure */
pLOADFILEOPTION pLoadFileOption;	/* pointer to optional extended load options */

Reads the transforms stored with an image in a FlashPix file.

Parameter	Description
pTransforms	Pointer to a transform structure.
pLoadFileOption	Pointer to optional extended load options. Pass NULL to use the default load options.

Returns

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