email_toan	Posted - Jun 10 2022 : 13:41:01 I'm seeing an unexpected behavior when comparing background image to a layer's image. Here's my code: ImageEnView1.IO.LoadFromFilePNG('320_240_line.png'); //background image ImageEnView1.LayersAdd(ImageEnView1.IEBitmap,0,0); //exact image as layer 1 I expected both images to be exactly over each other. However, when I zoomed in I can see they're out of alignment. I added a trackbar to control layer1's opacity to verify my observation. What I need to do to make it so they're exactly over each other?

xequte	Posted - Jun 12 2022 : 22:41:14 I see now. At higher zoom levels you can get slight movement due to rounding. You can fix this by explicitly enabling Layer editing: ImageEnView1.LayerEditingMode := True; Nigel Xequte Software www.imageen.com
email_toan	Posted - Jun 12 2022 : 19:52:04 Any zoom level. There is only one layer, layer 1. The other is the background image. I did not change the zoom filter so I'm assuming it's whatever the default is. tn
xequte	Posted - Jun 12 2022 : 16:34:44 I'm not seeing that when I recreate your project. What is the zoom level? Do both layers have the same zoom filter? Nigel Xequte Software www.imageen.com
