Hi,
I try to rotate the IEImageLayer after adding it to the IEImageViewer.
I'd like to have the image quality as it is in the RotateTool demo (I tried it with the same image) - but I don't know how to do it.
This is the snipped of my code which doesn't work correctly - the image is fuzzy after rotation.

iPor.LayersAdd( TIELayerKind(ielkImage));
TIEImageLayer( iPOR.CurrentLayer).Bitmap.Read(plik);
iPor.RotateTool.AutoCrop := false;

TIEImageLayer( iPor.CurrentLayer ).ResampleFilter := rfBicubic;
TIEImageLayer( iPor.CurrentLayer ).UseResampleFilter := True;
iPOR.CurrentLayer.Rotate := 45;
iPor.Update();

what could be the correct way to do it?

S.

Hi

For display quality, please see the example at:

You probably need to enable LayersRotationUseFilterOnPreview

Also, you will need to apply the layer rotation:
