TIEFileDlgPreviewEvent = procedure(Sender:TObject; Viewer:TObject; FileName:string; ParamsOnly:boolean) of object;


How to change an object type of Viewer from TImageEnVect to TImageEnMView?

There is unsupported ImageEn format.

I can tranform this file to multipage TIFF file and want to view this file in preview.
But in this case Viewer is TImageEnVect only.

Hi

The Viewer will always be a TImageEnMView when previewing multi-frame files (videos, DCX, animated gifs and multipage TIFFs) and a TImageEnVect for all other types.

However you can specify that your type is a multi-image type by adding its extension to IEGlobalSettings().PreviewAdditionalMultipageExts:

You can specify any extension for PreviewAdditionalMultipageExts, but then you need to ensure that you handle the OnPreviewFile event.

Yes, of course.
