Simple Polygon Trouble

Jared

Hello.
I am struggling with the proper syntax for inserting a polygon into a layout. I keep receiving the error "No overload with matching arguments...". An explanation of this error would be helpful as well as an example of how to insert a Simple Polygon.

Thank you,
Jared

Hi Jared,

basically this message means that there is no method variant (of several) which expects the arguments given in the call. You'll get this message for example on this line:

RBA::SimplePolygon::new("balbla")

because there are two initializers: one expecting a list of points and another expecting a box. If you want to create a simple polygon from a list of points, be sure you provide an array for the argument:

a = [ RBA::Point::new(0, 0), RBA::Point::new(100, 0), RBA::Point::new(100, 100) ]
RBA::SimplePolygon::new(a)

Some sample code would be helpful to understand your particular issue.

Regards,

Hello Matthias,
Thank you for your continued help. I am posting some example code, but it is for a different issue now. It is the name of the call for inserting a hole in a polygon. I was pretty sure that this would be correct, but it isn't:

cell.shapes(insignia_layer).insert(RBA::Polygon::insert_hole([dh1,dh2,dh3,dh4]))

The error says that there is no "insert_hole" method in the Polygon class.

Hi Jared,

A hole is actually a feature of a polygon, not an individual shape you can insert. You can insert a hole into a polygon, not a hole into a shapes collection, i.e.

hull_points = ... # array of RBA::Point
p = RBA::Polygon::new(hull_points)
hole_points = ... # array of RBA::Point
p.insert_hole(hole_points)

There is a description here: http://www.klayout.de/doc/programming/database_api.html#h2-1109. Maybe that is helpful.
