An image has multiple layers, and the scaling ratio of the image is set to not equal to 100. When you select and drag one of the layers, the entire image will shake. How to prevent this shaking?

Hi

I assume you mean when there is no background image and/or you drag outside the area of the background image?

In a layer editing application, Center should be false:

  ImageEnView1.Center := False;

Oh, I see. For performance some options that are CPU intensive are disabled while sizing/creating layers.

In this case it looks like DelayZoomFilter:

Please see the cmbPreviewQuality example at:
