Hello,

I want to load several Layers in an ImageEnView - and arrange and position the layers via Mouse - with Hitdetection between Layers and most importend with magnetic snap to each of the layers. (Moving one layer and within snapdistance the Layer "snaps" to the postioned Layer nearby).

Even though I did a quick grep through the source with "snap" and "magnetic" - the searchresults doesnt seem to do what I need.
Am I correct that something like that doesn't exist in the ImageEn Libary?

TiA,
Harald

Found IEView.Layers[i].LayerRect.IntersectsWith() -> for Hitdetection

and to clarify: I dont want to align / snap the layers on a Grid, I want to snap / align the layers on each other; some layer may be positioned and snap on that positioned layer...

TiA,
Harald

Hi Harald

I'm sorry, we only have grid snapping at this time. You might want to code something in the OnLayerMoveSize event to do it.

Ok - was hoping there was already something I could (re)use. But anyway - was a bit more work than thought but I was able to add the necessary events in OnLayerMoveSize and LayerNotifyEx to create something matching my expectatations.

Nice one, Harald. You might want to post your solution here. If it works well, we might add it as an option.
