Constructor

CadMarker(string text, Point2D pt, integer pixel_size)

A CadMarker at passed position text -string – text for marker object pt -Point2D – position for marker

pixel_size pt -integer – size marker is drawn at in pixels

Properties

.Text

Read/Write – string – Text displayed at marker

---

.Position

Example Code:

--[[  ------------------ MarkContourNodes ----------------------------    
   |  
   |  Insert a marker at each node on the passed contour  
   |  
  ]]  
  function MarkContourNodes(contour, layer)  
    local num_spans = 0  
    local ctr_pos = contour:GetHeadPosition()     
    while ctr_pos ~= nil do        
      local span  
      span, ctr_pos = contour:GetNext(ctr_pos)        -- create a marker at start of span  
      local marker = CadMarker("V:" .. num_spans, span.StartPoint2D, 3)        
      layer:AddObject(marker, true)        
      num_spans = num_spans + 1;     
    end -- while end
   -- if contour was open mark last point     
    if contour.IsOpen then  
       local marker = CadMarker("V:" .. num_spans, contour.EndPoint2D, 3)        
       layer:AddObject(marker, true)     
    end -- if end
  end -- function end
