This function causes the LEADTOOLS File Information / Load functions to only check the files signature when trying to determine the files format.

The default behavior when calling LEADTOOLS File Information and Load functions, is that if the files signature does not match one of the known file format signatures, then LEADTOOLS will allow each of the available file format filters a chance to properly identify the files format.  This can both slow down an application and unnecessarily use up system resources if the application attempts to load files of an unsupported format (i.e. non-image files).

When Fast File Info is enabled, the file will be rejected if the signature does not match one of the known file format signatures and thus the file format dlls will not unnecessarily be loaded or called.

You must call this function prior to calling any LEADTOOLS File Information or Load/Save functions.
