function LibWebP_IsAvailable(ExeFolderOnly: Boolean; RaiseExcept: Boolean): Boolean; overload; function LibWebP_IsAvailable(const DLLPath: String = ''; RaiseExcept: Boolean = False): Boolean; overload;
Description
Checks if the IEWebP DLL is available and initializes it.
If ExeFolderOnly is true, only the folder of the application EXE is checked for IEVision DLLs.
Alternatively, you can specify a path to the DLL, which can either be a full filename or a folder.
If RaiseExcept is true, an exception will occur if the DLL is not found.
if not LibWebP_IsAvailable() then ShowMessage( 'WebP DLL not found! Please reinstall' );
// Which is the same as: if not ( iepiWebP in IEGlobalSettings().RegisterPlugIns([ iepiWebP ]) then ShowMessage( 'WebP DLL not found! Please reinstall' );
