Flash in a painting in the Graduated scale.    Relatively simple principle, if we use creative tools (scale painting lines, text ...), then seemed to be a bit tedious; 

  Jsfl If so, can be relatively easy, as it must be resolved in only some painting and calibration lines to create some text. 
  Here, I wrote a command sequence, very simple to use, Figure: 

  Code as follows: 

  Function drawRuler () ( 
  Var _width = Number (result.width); 
  Var _height = Number (result.height); 
  Var _grad = Number (result.grad); 
  Var grad_length; 
  Var start = 1; 
  Dom.addNewLine ((x: 0, y: 0), (x: _width, y: 0)); 
  Dom.addNewLine ((x: _width, y: 0), (x: _width, y: _height)); 
  Dom.addNewLine ((x: _width, y: _height), (x: 0, y: _height)); 
  Dom.addNewLine ((x: 0, y: _height), (x: 0, y: 0)); 
  For (var i = _grad * 2; i <= _width; i = _grad) ( 
  Start; 
  If ((start% 10) == 0 | | start == 0) ( 
  Grad_length = _height/2.5; 
  Dom.addNewText ((left: i-5, top: grad_length, right: i 5, bottom: grad_length 10)); 
  Dom.setTextString (start/10); 
  Dom.setElementTextAttr ( 'size', 12); 
  Dom.setElementProperty ( 'alignment', 'center'); 
  Dom.setElementTextAttr ( 'bold', false); 
  Dom.setElementTextAttr ( 'italic' false); 
  Dom.setElementTextAttr ( 'face', 'Times New Roman'); 
  ) Else if ((start% 5) == 0) ( 
  Grad_length = _height / 3; 
  Else () 
  Grad_length = _height / 5; 
  ) 
  Dom.addNewLine ((x: i, y: 0), (x: i, y: grad_length)); 
  ) 
  Dom.selectNone (); 
  ) 
  Var dom = fl.getDocumentDOM (); 
  Var lib = dom.library; 
  Var result = dom.xmlPanel ( "file: / / / ruler.xml"); 
  If (result.dismiss == "accept") ( 
  Fl.outputPanel.clear (); 
  DrawRuler (); 
  ) 

  Which xml documents: 

  <dialog Buttons="accept, cancel" title="刻度尺"> 
<vbox>
<hbox>
  <label Value="宽: "control="width"/> 
  <textbox Id="width" value="450" size="5"/> 
  <label Value="高: "control="height"/> 
  <textbox Id="height" value="50" size="5"/> 
  <label Value="刻度: "control="grad"/> 
  <textbox Id="grad" value="5" size="5"/> 
  </ Hbox> 
  </ Vbox> 
  </ Dialog> 

  Enjoy!
