Scale-independent plug-in objects


Recommended Posts

Does anyone know of any good resources for making scale-independent PIOs? I'm having some trouble with linear PIOs dropping in fine but with point PIOs needing a "Wakeup" before they draw properly.

At the moment, when a new PIO is drawn, the script gets the object's layer, then the layer's scale from that. Then I have a usable scale factor which can be used to draw the parts of the object at the right size to remain scale-independent.

Oddly enough, as I mentioned, the same code that does this works fine on linear PIOs but fails when I try to use it in a point PIO.

Anyone have experience with these non-scaling PIOs?

I think I figured something out: Point PIOs (as a tool) begin to execute immediately when you select them, whereas linear PIOs only began to execute after the user has defined the two points for the linear PIO.

Does this sound right? Can anyone verify?

Edit: When I make a PIO symbol of this script, it works fine now, since the user doesn't define any points and instead just drags the item out of the Resource Browser.

Still, if anyone has resources on the scale-independent PIOs, I'd love to hear from you, just so I can run the appropriate error checks and such...

It took me years to perfect this code:


    {******* non-scaling PIO code starts here ***************}


IF GetCustomObjectInfo(objectName, objectHand, recordHand, wallHand)

& GetLayer(objectHand)<>NIL THEN Layer(GetLName(GetLayer(objectHand)));



{ Your code will go here, this poly is an example }


Poly( -5*mm,1*mm,





{this temp. active layer change is necessary to avoid text size problems if the PIO

is redrawn when not in the active layer, and the active layer has a different scale}
