I use TImageEnView to browse different images. When I zoom out and move the current image position, I want to keep the current zoom ratio and position when loading and browsing the next image. How can I achieve this?

Hi

The zoom value should be maintained when loading a new image (as long as you don't have AutoShrink/AutoStretch turned on).

The position is reset upon loading so you would need to store and set the ViewX/Y:

Thank you. I want to know how to freely move images by dragging them with the mouse in TImageEnView?

Hi

Ensure miScroll is specified for MouseInteractGeneral:

When the screen width and height are both greater than the height and width of the image, can it move freely up, down, left, and right?

What I mean is, I want to press the left mouse button and drag the image to any position

For that you would need to treat the background image as an image layer. Set MouseInteractLayers to mlMoveLayers:

http://www.imageen.com/help/TImageEnView.MouseInteractLayers.html

You will also need to disable the locking of Layer 0 (the background).

ImageEnView1.Layers[0].Locked := False;
ImageEnView1.Layers[0].Selectable := True;
