There are two ways to specify transfer syntax (compression) for DICOM image saving: SaveFormat parameter, and TransferSyntax DICOM format option. SaveFormat (ImGearSavingFormats) is an easy-to-use shortcut, while TransferSyntax option provides the full selection of transfer syntaxes for image saving.
