The following features are supported:

IEGlobalSettings().RegisterPlugIns([ iepiSevenZip ]);

// Load the first file in a zip and show buttons to allow navigation
ImageEnView1.ShowButtons := [ iebtPrevious, iebtNext ];
ImageEnView1.IO.LoadFromFileZIP( 'C:\', 0 );

// Extract all files from a zip file to D:\Out\ (Recreating the internal zip folder structure)
ImageEnView1.IO.ExtractFromFileZIP( 'C:\', -1, 'D:\Out\', True );

// Display all files within a zip (ignoring the internal folder structure)
ImageEnMView1.FillFromZIP( 'C:\Files\' );

// Display files within the root folder of the zip
ImageEnMView1.FillFromZIP( 'C:\Files\', '\' );

// Display files within the zip folder \Holidays\Italy\
ImageEnMView1.FillFromZIP( 'C:\Files\', '\Holidays\Italy\' );

// Output all images in a ZIP file to PNG
