Attached is a graphic that shows page 1 of a black and white tiff rendered differently by three things: 1) a TImageEnMView, 2) a TImageEnVect, and 3) Windows Fax and Photo Viewer. Notice that 1) and 3) are a lot better rendered than 2). Why is that? I've tried setting BitmapResampleFilter and that doesn't seem to change anything.

Currently, I load the file with a simple call to ImageEnMView1.MIO.LoadFromFileTiff. I render the selected image in the MView with the following code, where Number is the idx of the image clicked on:


    ImageEnVect1.IEBitmap.Assign( ImageEnMView1.GetTIEBitmap( Number ) );
    ImageEnVect1.Update;
    ImageEnMView1.ReleaseBitmap( Number );




Any ideas on how the visible TIFF quality could be better with TImageEnVect?

Found it! I had to set ZoomFilter, not BitmapResampleFilter!
