用aardio绘图进行GDI+的绘图还很简单,效率也不错.

import win.ui;

/*DSG{{*/

var winform = win.form(text="aardio form";right=759;bottom=469;parent=...)

winform.add()

/*}}*/

    bottomPad = 20;

        var graphics = this.tmpBuffer

        //设置文字抗据齿

        //graphics.smoothingMode = 4/*_GdipSmoothingModeAntiAlias*/ ;

        

        //消除走样，且边作平滑处理

        //graphics.textRenderingHint = 3/*_GdipTextRenderingHintAntiAliasGridFit*/;

  使用plus控件简易版。

  
  

  
  

  import win.ui;
  
  import gdip.pen;
  
  /*DSG{{*/
  
  var winform = win.form(text="aardio form";right=759;bottom=469)
  
  winform.add(
  
  plus={cls="plus";left=111;top=100;right=576;bottom=372;notify=1;z=1}
  
  )
  
  /*}}*/
  
  
  
  
  
  
  
  winform.plus.onDrawContent = function(graphics,rc){
  
   var pen = gdip.pen(gdi.ARGB(0,0,255,255),1);
  
   
  
      graphics.drawLine(pen,0,0,50,50)
  
      graphics.drawLine(pen,50,50,150,250)
  
      graphics.drawLine(pen,150,250,250,0)
  
      
  
      pen.delete();
  
  }
  
  
  
  winform.show() 
  
  win.loopMessage();

  非快照方式取出plus上绘图的缓存数据并保存为图片:

  import win.ui;
  
  import gdip.pen;
  
  /*DSG{{*/
  
  var winform = win.form(text="aardio form";right=759;bottom=469)
  
  winform.add(
  
  plus={cls="plus";left=111;top=100;right=576;bottom=372;notify=1;z=1}
  
  )
  
  /*}}*/
  
  
  
  
  
  winform.plus.onDrawContent = function(graphics,rc){
  
   var pen = gdip.pen(gdi.ARGB(0,0,255,255),1);
  
   
  
      graphics.drawLine(pen,0,0,50,50)
  
      graphics.drawLine(pen,50,50,150,250)
  
      graphics.drawLine(pen,150,250,250,0)
  
      
  
      pen.delete();
  
  }
  
  
  
   
  
  winform.show()//先显示窗口再保存图片
  
  
  
  //创建一个指定宽高的画板
  
  var bmp =gdip.bitmap(winform.plus.width,winform.plus.height)
  
  bmp.graphics.drawCachedBitmap( winform.plus.cacheBitmap)
  
  bmp.save("c:\test.png")
  
  
  
  
  
  win.loopMessage();

  注意先显示窗口再绘图保存.
