Hi,

I have an PNG image with Dimensions 500 x 250.
Width : 500 pixels
Height : 250 pixels

When I displyed it on ImageEnMView, the quality seems to have degraded even I specify the same width and height in thumbnail.

Below are my code to display the Image :

ImageEnMView1.ThumbWidth := 500;
ImageEnMView1.ThumbHeight := 250;

In ImageEnMView1ImageIDRequestEx :

tempIE.IO.Params.Height := 250;
tempIE.IO.Params.width := 500;
tempIE.IO.Params.PNG_Filter:=ioPNG_FILTER_PAETH;
tempIE.Proc.Resample(500,250,rfLanczos3);
tempIE.ZoomFilter := rfLanczos3;
tempIE.Zoom := 100;

I also notice that with shadow turn on, the quality of the image becomes more blur, especially with characters.Not so bad with Image.

How can I make the image in ImageEnMView to show exactly the same quality as displayed in Windows Photo Viewer ?

Have you set ImageEnMView1.ThumbnailDisplayFilter := rfLancoz3?

What do you have StoreType Property set as... ietNormal or ietThumb?

Resample and use of a ZoomFiler may also affect quality expecially with text.
