L_LTFIL_API L_INT L_ReadFileTransforms(pszFile, pTransforms, pLoadOptions)

L_TCHAR* pszFile;	/* file name */
pFILETRANSFORMS pTransforms;	/* pointer to a transform structure */
pLOADFILEOPTION pLoadOptions;	/* pointer to optional extended load options */

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

Parameter	Description
pszFile	Character string containing the FlashPix file name.
pTransforms	Pointer to a transform structure.
pLoadOptions	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.

Comments

Note:	Page number is specified in the LOADFILEOPTION structure. To load a FlashPix file with or without the transforms, see FlashPix Transforms Options.
