I believe that bottom object in your picture is Text, yes? And if you grab a corner and stretch it, the font size kinda doesn’t matter anymore?
In both [I]groov [/I]and PAC Display, there are certain objects where the text size stays the same, and others where stretching the object will make the text bigger. I’ve pondered these differences for [B][I]groov[/I] in this post[/B], but not for PAC Display.
In PAC Display, you can see your X/Y, W/H values as you change the size of the object, which is handy if you’re concerned about having a specific size. In [I]groov[/I], there’s a grid which objects are snapped to. I suppose I have my most/least favorite options in each.
To answer your question, I suppose it is known, but I think the difference would be more significant on the objects where text sizes are NOT changed when you stretch the object (like a button and a table)?
