function IEAddExtIOPlugin(const FileName : string) : Integer;
Adds support for extra file formats using the ImageEn input/output plug-ins (DLL's) that can be downloaded from the Registered Users download page.
Available plug-ins allow you to load and save JBIG and other formats. All include source code if you need help to you write your own plug-ins.
Result is the FileType for the added formats, e.g. ioOtherDLLPlugIns, ioOtherDLLPlugIns + 1, etc. This can be used by methods such as LoadFromStream
Note: From v6.1.0, dcrawlib.dll is no longer used for Camera Raw format support, use ielib
A plugin can include more than one file format. For example, imagemagick.dll adds PCD, DICOM, FITS and many others.
Please read license terms for each plugin downloaded from imageen.com web site.
