is possible to create something like this?
To change the width and height of an object
I wrote code to draw a rectangle and allow it to be stretched or moved, depending on where it was touched. I think it will be embedded in the mapping module of
GPS4PPC v2.0. But because the idea was to define a zoom area the aspect ratio was constrained to the screen's. Also there were no "handle" markers as is common when drawing rectangles like this.
But it might form a basis for what you want. Feel free to ask (especially if you cannot find the relevant code; I have much more recent versions!).
HTH, Mike.
Edit: in attached code you can grab the rectangle on each side, at each corner, or anywhere within, and drag appropriately.
