Hello,
I would like to move an image over the screen.
If I use Top property of the image and increase the value, I get unsmooth moving of the image (following the changing top value by 1).
If I try with SetViewXYSmooth, I like the smoothness, but the scrolling happens too quickly, (there seems to be no way of controlling the speed of scrolling).
Is there any way I could get relatively slow and smooth moving of the image over the screen?

Hi
Animation is something that we will consider for a future version.

Hi Nigel,
thank you so much for your help. I will try with PosX and PosY.
I would like to come to "animation", but still, with worked out (not too perfect) version of it. For artistic purposes, the "curved" line is somehow more efficient than straight ( full animation programs).
Anyhow,I would be very glad if, somewhere in the future, Imageen would make support for zooming a single layer.
Thanks again.

Hi Borut
It sounds like you are looking for some type of animation type solution. This is something that has been discussed a number of times on the forum, but is not specifically supported.
If you are only looking to animate a single layer, then you would do that just by updating its PosX, PosY, Width, Height properties and then update the TImageEnView.
Unfortunately I don't think it would animate "cleanly". Ensure you enable LayersCaching to improve the performance.

Hello,
I tried your suggestions and the zooming worked well.
I used different functions:
1)ImageEnView1->SetZoomSmooth
2)ImageEnView1->PrepareTransition();
ImageEnView1->RunTransition(iettPanZoom,
Rect(),
Rect(),
True);
3)Transitions with prebuild PanZoom effects
Then I tried changing some properties of the image during the "transitions". I used Timer to trigger the change and got some success (troubles with blinking) with method 1) and 2), while working with prebuild PanZoom did not allow me to make a change in an image with a Timer.
I also tried zooming a particular layer in ImageEnView (with all three methods), but unfortunately got nothing. Zooming affects all layers ( I would like to zoom a single one ). And it also seems, that zooming changes only the display of the layer, so when assigning that layer to another ImageEnView (ImageEnView2) element, it copies the untransformed image, although I can actually watch the zoom transformation in ImageEnView1.
Am I missing something in my efforts to zoom a single layer of the image?

Thank you. I will try both suggestions and let you know.

You can control the speed of SetViewXYSmooth:

Another possibility is using Pan-Zoom effects. Please see this demo:
