Hi;

I set TImageEnView.Scrollbars to ssBoth. When I add a layer that goes out of the box, the scrollbars does no come visible.

I also tried to set ScrollBarsAlwaysVisible := True; in this case they are visible but they have no slider visible.

Is it a way to make them visible? or ... is it a way to have an auto-zoom or a zooming option to make all visible?.

I tried FIT, autoshrink and etc etc, but no case.

Thank you!

HI Dany

Please add loDynamicCanvas to LayerOptions:

I already tried loDynamicCanvas it before asking, nut when I use that option the component has a strange behavior. BTW, what happen with the Scrollbars?

Here you can see an example: this is layer 0:



Then I add a layer with other image:



But no scrollbars visible, and also FIT does not help me to show the whole image.

Hi

Yes, fit only applies to Layer 0. You should not use the Center with loDynamicCanvas.

Let me check what options are available when I'm back in the office in early November.

Let me say that now I see it fine with Center + loDynamicCanvas. Only thing that is missed (but I don't know why), are the ScrollBars.

Hi Dany

I'm not able to reproduce that.



Please add this line to the create event for the demo: \Demos\LayerEditing\Layers_AllTypes\Layers.dpr

ImageEnView1.LayerOptions := ImageEnView1.LayerOptions + [loDynamicCanvas];

Load a background image, and then add a shape and drag it out of view. Does the scrollbar appear?

Does View > Zoom to Fit correctly display all content?
