>> A heartfelt thanks to Michael for Versatile Wand - very nice! But

>> (1) Wand currently only performs 8-connected searches,

> The built in wand tool in v1.43a will be based on Versatile Wand, so

>> (2) FloodFill uses 4- or 8- connected which the user selects by

> That is correct.
>
>> (3) "Analyze particles..." (as Analyzer, or is it
>> ParticleAnalyzer? or PolygonFiller?) uses FloodFill and Wand but
>> flood filling is only 8-connected.
>
> The particle analyzer is currently only 8-connected but it will be
> easy to add a 4-connected option once the Wand class is updated to
> support 4-connected outlining.
