Threaded thumbnails demo
Yet another thumbnails demo, this time showing how to make the thumbnails in a seperate thread. There is a small problem which I belive is caused by the Delphi jpeg unit which sometime will render a thumbnail empty. With empty I mean that it has the correct width and height but not the image itself but just a white rectangle. If you figure out how to fix it please tell me so I can fix it. It only happens once and awhile so it is not easy to pinpoint what is causing it.
This demo also fix some problems which was present in previus thumbnail demos so if you had problems with previus demos try this one.
Using a diffrent imagelib seems to solve the problem reagarding blank thumbnail. I strongly recomend ImageEn but also GraphicsEx is a good one.
You need rkView installed to run this demo. You find it under components.
Download project with source
The same demo using ImageEnIO for loading and making the thumbs. You need to have ImageEn installed to compile and run this demo.
