Hi, I use TImageEnMView and LoadFromFileTIFF in delphi XE2
Version: ImageEn 10.2.0

I use

iemv1.ImageCacheSize:=200;
iemv1.StoreType:=TIEStoreType.ietFastThumb;
iemv1.MIO.LoadFromFileTIFF(current_file);

but it takes >20 seconds to load the file.
Thumbnails are not needed at this point.
can I disable thumbnails, or set the rendering to async?
Thanks & with best regards, Thomas.

Hi Thomas

You can just load the frames as they are needed using ImageEnMView1.LoadFromFileOnDemand():
