Hi. First of all congratulations for creating such a great library and giving great support in its use!

I have a little problem working with layers: I have a background image and a second layer which I can move around and insert annotations into after having specified Image.ObjLayer[IEV_NEXT_INSERTED_OBJECT] := 1;
I'd like to be able to insert annotations into the entire ImageEnVect area and not limit myself to the layer dimensions, which varies according to zoom, panning etc...
Is it possible to expand the layer so that it occupies the entire client area or should I code it by hand handling the onresize event? Is there any other way?

If you want the layer to be the same size call LayersSync before you add a layer:
ImageEnVect1.LayersSync := True;
iLayer := ImageEnVect1.LayersAdd;

If LayersSync is true all layers must have the same size.

You can also position a layer and set the layer dimensions with
ImageEnVect1.Layers[ilayer].PosX
ImageEnVect1.Layers[ilayer].PosY
ImageEnVect1.Layers[ilayer].Width
ImageEnVect1.Layers[ilayer].Height
