Re: [JAVA2D] Performance problem with JDK6 Update10 Build22

[java2d]

Hi Dimitri

Here's the code that was so slow with d3d enabled. 

[code]
//XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
// data
//XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
private float _phase = 0f;

private boolean _anim = false;

private SoftReference<BufferedImage> _imgCacheOld;
private SoftReference<BufferedImage> _imgCacheNew;
private Insets _insets;

//XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
// methods
//XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

public void init(JComponent container, JComponent oldSheet, JComponent 
newSheet) {
//  TimedSout out = new TimedSout();

//  out.sout("init with 2 sheets... start");

  GUIUtils.renderNow(container, oldSheet);
  GUIUtils.renderNow(container, newSheet);

//  out.sout("init with 2 sheets... rendering complete");

  _imgCacheOld = AppUtils.captureComponentToImage(true, oldSheet, 
TransitionEffect._blurOldSheet, _imgCacheOld);
//  out.sout("init with 2 sheets... copied 1st comp to image... this takes a 
LONG TIME");

  _imgCacheNew = AppUtils.captureComponentToImage(true, newSheet, 
TransitionEffect._blurNewSheet, _imgCacheNew);
//  out.sout("init with 2 sheets... copied 2st comp to image... this takes a 
LONG TIME");

  _insets = container.getInsets();
//  out.sout("init with 2 sheets... end");

}
[/code]

The slowdown occurs when the components are copied. If you look at the top of 
this thread you will find the code I use to copy a JComponent into a 
BufferedImage. The TimedSout class is something I was using to capture the time 
it took to perform each of these operations.

Thanks,
Take care,
Nazmul.
