rmholes

Remove holes in polyshape

Syntax

polyout = rmholes(polyin)

Description

polyout = rmholes(polyin) returns a polyshape object made up of the solid boundaries of the polygon polyin, with all the hole boundaries removed.

Fill Polygon Hole

Open Live Script

Create a polygon with a hole.

t = 0.05:0.5:2*pi;
x1 = cos(t);
y1 = sin(t);
x2 = 0.5*cos(t);
y2 = 0.5*sin(t);
polyin = polyshape({x1,x2},{y1,y2})

polyin = 
  polyshape with properties:

      Vertices: [27x2 double]
    NumRegions: 1
      NumHoles: 1

plot(polyin)

Figure contains an axes object. The axes object contains an object of type polygon.

Create a new polygon with the hole removed.

polyout = rmholes(polyin)

polyout = 
  polyshape with properties:

      Vertices: [13x2 double]
    NumRegions: 1
      NumHoles: 0

plot(polyout)

Figure contains an axes object. The axes object contains an object of type polygon.
