Re: Comparing pictures

Ji Jean-luc,

but the celltags are of variant type,
so you can store everything there…

you could simply define a class, with the parameters you need,
and set the celltag to an instance of that class.
so you can store multiple different values in a single cell tag

hope it helps,
