Hi,

I've implemented annotations pretty much as per the Vectorial Demo.

One problem though - when MouseInteractVT = miObjectSelect, it seems impossible to DEselect an object. No matter where on the image I click, at least one object is selected. This is also the case on the Vectorial Demo.

It's then impossible for the user to set the default pen & brush colors & styles (plus it seems very counter-intuitive)

Is there some property I'm missing to allow this?

Thanks
Stuart

TImageEnVect.MaxSelectionDistance

Declaration
property MaxSelectionDistance: integer;

Description
MaxSelectionDistance indicates the maximum distance (in bitmap pixels) from which an object may be selected.
If the user left clicks at a location beyond this distance, no object will be selected.

A value of -1 (the default) disables the maximum selection distance calculation (a click always selects some object).

Example

ImageEnVect1.MaxSelectionDistance := -1; // disables maximum distance
ImageEnVect1.MaxSelectionDistance := 10; // set maximum distance to 10 bitmap pixels

Perfect, thank you Bill. I knew it would be something simple I was missing. Cheers.
