Bugfix in 1.4.1_02

Java 2D
#1

Just was reading the release notes for 1.4.1_02 and stumbled across this fix (on the windows platform):

4713736 - Hardware acceleration for alpha channels (translucent images) is supported.

Unfortunately - the bugid is not a public one - anyone know what this entails?

#2

Ha, you beat me to it. I just came here to post the exact same message. Where’s Trembovetski to fill us in on the details??

#3

What is the URL to get the info on the sun’s page??

#4

just a guess, but would it be through using :-


graphicsConfiguration.createCompatibleImage(width,height,Transparency.TRANSLUCENT);

? ::slight_smile:

#5

Do you have a link? I can’t find it mentioned in the release notes…

#6

well, it was at
http://java.sun.com/j2se/1.4.1/ReleaseNotes.html

but apparently its been removed.

i didn’t get around to fully testing it, but translucent images with automatic images (using toolkit.getImage()) didn’t appear to be accelerated.

well, maybe it’s show up in 1.4.2.

anyone notice any other bug fixes removed from the list?

I was also fooled by the release notes. I’ve posted the missing entries on javalobby.org http://www.javalobby.org/threadMode3.jsp?message=58865995&thread=7018&forum=61

But again, here are the entries that have been removed from the release notes:

  • 4713736 Hardware acceleration for alpha channels (translucent images) is supported.
  • 4768906 A way to share native offscreen surfaces outside java2D is provided.
  • 4769335 Support for 4444 ARGB image format is provided.
  • 4769345 A way to avoid disabling hardware acceleration for images with stolen raster is provided.
  • 4808940 The license agreement dialog is displayed upon first time use of either Java Plug-in or Java Web Start.
  • 4811862 The installer shows a license based on the locale detected on the target system.
  • 4813791 Applet tag did not invoke Sun VM with MSN Explorer.

Hehe, no info for you about our dirty secrets!

I’m taking that as meaning those bugs are fixed but they missed the _02 release… or maybe code for them was switched off at the last minute because of the discovery of some problem related to it.

Hmmm… I wonder how long we will have to wait for _03 :slight_smile:

I’t’s just that in _02 we’ve implemented some features which didn’t get appropriate testing due to time constraints, so we’re a little reluctant to let people use it.

But we’re now thinking that may be it’d be a good idea to let people try it at their own risk as a preview of things to come. We’ll see.

yes yes yes!!!

If it means we get a bug free version sooner, I’m all for the idea.
As it is, fullscreen still has several bugs, so we might as well get all the bugs out in the open at once :smiley:

though if it means another 30mb download (when i still havn’t finished downloading _02 :p) i’m gonna cry ???

would it be possible for Sun to release upgrade patches for the jdk as well?
(seeing as the difference between _01 and _02 is probably <1%)

#12

maybe an early access 03 version? that would do the trick, i think. :slight_smile:

#13

The features I’ve mentioned are actually already in _02, they just turned off by default, but they can be turned on with some flags. I’m about to finish the info on how to turn them on and use appropriately. Tomorrow, may be…
