shape script and bounding box

[spirax]

I have some elements with shape scripts, and their bounding boxes (series of little black boxes around the element when selected) is far larger than the shape.
This means that connectors/association lines don't join the shape - there's a big gap around it.
I have tried setting a defSize(x, y) but this has not made any difference. There doesn't seem to be any way of changing this box via a shape script - or is there?
Thanks

For the majority of shape script commands, the parameters you supply are not a size in pixels but a percentage of the drawing area (bounding rectangle). So, for example,

Code: [Select]

rectangle(0,0,50,50);does not create a 50x50 pixel square, it creates a rectangle that fills the top left quarter of the overall shape. For a 50x50 square, you would need

Code: [Select]

defsize(50,50);
rectangle(0,0,100,100);

Thanks, but I'm using moveto and lineto.

Moveto() and Lineto() both take percentage values.

Defsize() takes pixel values, and you only want one in a shape script unless you have if...else constructs in which case you might choose to have one in the if block and one in the else block. I can't think of any reason why it wouldn't work unless it's the element type: what element type are you working on?

Not sure what you mean - but the shape script is for a stereotype which is extending a Requirement metaclass.

Basically its a "shield" shape - here is the script I'm using.
 
Oh, and this is version 8 build 862.

Just noticed when I scale this up a bit, the defsize isn't working - I hadn't noticed because it had shrunk the overall size of the shape! So, I'm actually no better off with all these defsizes  

Code: [Select]

shape main{
      noshadow = true;
      fixedAspectRatio = true;
      startpath();
      defsize(40, 50);
      moveto(25, 5);
      lineto(50, 5);
      lineto(50, 35);
      lineto(25, 35);
      lineto(25, 5);
      endpath();
      setfillcolor(100, 100, 50);
      fillandstrokepath();
      
      startpath();
      defsize(40, 80);
      moveto(25, 35);
      lineto(25, 75);
      lineto(50, 100);
      lineto(50, 35);
      lineto(25, 35);
      endpath();
      setfillcolor(255, 255, 255);
      fillandstrokepath();
      
      startpath();
      defsize(40, 80);
      moveto(50, 35);
      lineto(50, 100);
      lineto(75, 75);
      lineto(75, 35);
      lineto(50, 35);
      endpath();
      setfillcolor(100, 100, 50);
      fillandstrokepath();
      
      startpath();
      defsize(40, 50);
      moveto(50, 5);
      lineto(75, 5);
      lineto(75, 35);
      lineto(50, 35);
      lineto(50, 5);
      endpath();
      setfillcolor(255, 255, 255);
      fillandstrokepath();
}

thanks

You have 4 defsize commands but only the first one (or maybe the last one - I forget which) counts. I'm guessing you want the total size of the shape to be 80x130, in which case you need something like this:

Code: [Select]

shape main{
      noshadow = true;
      fixedAspectRatio = true;
      defsize(80,130);
      startpath();
      moveto(0, 0);
      lineto(50, 0);
      lineto(50, 35);
      lineto(0, 35);
      lineto(0, 0);
      endpath();
      setfillcolor(100, 100, 50);
      fillandstrokepath();
      
      startpath();
      moveto(0, 35);
      lineto(0, 75);
      lineto(50, 100);
      lineto(50, 35);
      lineto(0, 35);
      endpath();
      setfillcolor(255, 255, 255);
      fillandstrokepath();
      
      startpath();
      moveto(50, 35);
      lineto(50, 100);
      lineto(100, 75);
      lineto(100, 35);
      lineto(50, 35);
      endpath();
      setfillcolor(100, 100, 50);
      fillandstrokepath();
      
      startpath();
      moveto(50, 0);
      lineto(100, 0);
      lineto(100, 35);
      lineto(50, 35);
      lineto(50, 0);
      endpath();
      setfillcolor(255, 255, 255);
      fillandstrokepath();
}

That's what I started with - the bounding box is way outside the shape. How do I get the bounding box to be the same size as the shape?

[KP]

Did you copy and paste my whole solution? I changed a lot of the numbers in the lineto() and moveto() commands: I replaced all x values of 25 with 0 so the left edge of the shape is on the edge of the bounding rect, replaced all x values of 75 with 100 to fix the right edge, and all y values of 5 with 0 to fix the top edge.

Oh! no I didn't, sorry.  But yes that works. Thanks.
