If you try to load all the full-size pages of a multi-page file (such as TIFF) into our image list control, the time and memory needed will increase dramatically as the number of pages increase.
The attached LEADTOOLS 16.5 C# project optimizes the process by performing the following steps:
1. It only loads small resized thumbs in the list instead of full images, with only one full-size image loaded into the RasterImageViewer control.
2. It allocates empty list items for all images, but only loads thumbnails for the items that are actually displayed.
3. If the user scrolls to change the visible items, new thumbnails are generated as needed.
4. If the user changes the currently selected list item, the full-size image will be loaded.
