1. I have images of different sizes in my ImageEnMview control. This means that smaller images in larger thumbnails may look PIXELATED:



So doesn't TmageEnMView have a ZoomFilter property like TImageEnView?

2. I add several TIEBitmap to a TImageEnMView with this code:

ImageEnMView1.AppendImage(AIEBitmap);


I need to avoid bit-identical duplicates in the ImageEnMView. So has ImageEnMView a built-in property NoDuplicates? If not, I would have to implement my own by calculating the Hash of each IEBitmap and comparing it with the Hash values of the images already in the ImageEnMView. Since ImageEn has its built-in Hash algorithm methods: Which is the FASTEST?

UPDATE: TImageEnMView has both a ThumbnailDisplayFilter and a ThumbnailResampleFilter. I've set both to rflanczos3: https://app.screencast.com/YghwUPYvxvHAE
Do they work when small images are displayed in large thumbnails at a normal zoom factor?

Hi Peter

1. As per the documentation, there are two zoom filter options depending on whether they are sized as they are added, or as they are displayed:
