Description This method retrieves the number of images in the specified file. This method is available for TIFF, PDF, MO:DCA, GIF, FAX and DCX file formats. The function can also be called for JPEG, PNG, BMP, IOCA, WMF, EMF, PCX, CLP, TGA or CALS files, but the return value will always be 1, because these file formats cannot contain more than one image.
Syntax Ret = [BiDib.]GetNumberOfImagesInFile FileName Error
Remarks Ret Long Number of images, or 0 on error.
FileName String Path and name of the file.
Error Long Retrieves the error code. Available error codes are listed in the LoadImageIntoDIB section.
Programming notes The GetNumberOfImagesInFile method determines the file format based on the file content, not the extension, so any extension can be used for the files.
