Miguel,

I'm trying to get Jmol running with open source virtual machines [1], and 
while the application does not work yet, the renderer itself does, using the 
Swing3D class...

Using the Awt3D, however, does not work. I've been talking to Sven_M on irc 
(#classpath), and he thinks it has to do with the transparency the Gtk 
backend uses. That is, Component.createImage() returns a 
gnu.java.awt.peer.gtk.GtkImage, which uses RGBA instead of RGB, and thus 
things get drawn transparent.

Added a line in Awt3D.java makes at least a black background again:

  public void startProduction(ImageConsumer ic) {
    if (this.ic != ic) {
      this.ic = ic;
      ic.setDimensions(windowWidth, windowHeight);
      ic.setHints(ImageConsumer.TOPDOWNLEFTRIGHT |
                  ImageConsumer.COMPLETESCANLINES |
                  ImageConsumer.SINGLEPASS);
    }
    for(int i=0;i<pBuffer.length;i++) pBuffer[i] |= 0xFF000000; // RGBA thingy
    ic.setPixels(0, 0, windowWidth, windowHeight, colorModelRGB,
                 pBuffer, 0, windowWidth);
    ic.imageComplete(ImageConsumer.SINGLEFRAMEDONE);
  }

But in the Integration.java the water is gone...

Sven_M also noted that we should use:

  Awt3D(Component component) {
    this.component = component;
    // old code: colorModelRGB = ColorModel.getRGBdefault();
    colorModelRGB = Toolkit.getDefaultToolkit().getColorModel();
  }

But that did not improve it too.

It seems that the problem is the transparency. Miguel, do you have an idea why 
the water does not get drawn?

Below is the full IRC log.

[2005-11-27 21:29:38] <egonw_> mjw: I got the Jmol renderer working with jamvm
[2005-11-27 21:29:42] <theBohemia1> gcj-crew: ping
[2005-11-27 21:29:48] *** theBohemia1 is now known as theBohemian.
[2005-11-27 21:29:55] <egonw_> mjw: better -> it just works... (did not have 
to do much)
[2005-11-27 21:30:00] <mjw> egonw_, Woot!
[2005-11-27 21:30:01] <egonw_> it's just very slow
[2005-11-27 21:30:04] <theBohemian> mjw: hi
[2005-11-27 21:30:05] <mjw> screenshot! screenshot!
[2005-11-27 21:30:13] <egonw_> mjw: mind... it's not the Jmol application...
[2005-11-27 21:30:16] <egonw_> just the renderer
[2005-11-27 21:30:22] <theBohemian> mjw: is there an ant task that does bc 
compilation nicely?
[2005-11-27 21:30:37] <egonw_> mjw: will post a screenshot...
[2005-11-27 21:30:53] <mjw> egonw_, jamvm is not the faster engine around. Try 
kaffe, cacao or natively compile it with gcj for a nice speed boost.
[2005-11-27 21:30:54] <egonw_> flickr.something... that's a place where one 
can upload images, right?
[2005-11-27 21:30:58] <theBohemian> mjw: something more sophisticated than 
calling exec
[2005-11-27 21:31:24] <mjw> theBohemian, I never use ant to be honest.
[2005-11-27 21:31:24] <egonw_> kaffe gives error:
[2005-11-27 21:31:30] <egonw_> java.lang.ClassCastException: can't cast 
`java/awt/image/BufferedImage' to `gnu/java/awt/peer/gtk/GtkImage'
[2005-11-27 21:31:32] <theBohemian> mjw: :(
[2005-11-27 21:31:35] <mjw> theBohemian, But I believe green made something. 
Let me look it up.
[2005-11-27 21:31:38] <egonw_> there a -D option for that right?
[2005-11-27 21:32:03] <mjw> egonw_, Maybe 
-Dgnu.java.awt.peer.gtk.Graphics=Graphics2D
[2005-11-27 21:32:07] <theBohemian> mjw: thanks
[2005-11-27 21:32:11] <mjw> If you have compiled with cairo support.
[2005-11-27 21:32:26] <Sven_M> Yeah.
[2005-11-27 21:32:31] <theBohemian> egonw_: try a newer cp-snapshot for kaffe
[2005-11-27 21:32:33] <egonw_> mjw: no, that does not help...
[2005-11-27 21:32:45] <theBohemian> egonw_: mjw fixed this classcast thing a 
few days ago
[2005-11-27 21:32:46] <mjw> Also you might need kaffe CVS since it got just 
upgraded today with the latest GNU Classpath.
[2005-11-27 21:32:54] <egonw_> ack
[2005-11-27 21:33:07] <Sven_M> mjw: Where was the cast?
[2005-11-27 21:33:15] <mjw> http://spindazzle.org/gcjlib/
[2005-11-27 21:33:20] <mjw> Sven_M, cast?
[2005-11-27 21:33:27] <Sven_M> mjw: You fixed a GtkImage cast?
[2005-11-27 21:33:34] <mjw> Maybe
[2005-11-27 21:33:37] <mjw> I don't remember.
[2005-11-27 21:33:40] <Sven_M> That shouldn't happen.
[2005-11-27 21:33:42] <Sven_M> theBohemian: ?
[2005-11-27 21:33:43] <mjw> See the patches list if I did :)
[2005-11-27 21:33:54] <guilhem> egonw_: yes try the latest kaffe CVS.
[2005-11-27 21:34:02] <Sven_M> Last time I worked on GtkImage there were no 
unchecked casts to GtkImage in the Classpath code.
[2005-11-27 21:34:10] <egonw_> guilhem: is there a kubuntu breezy deb for 
that?
[2005-11-27 21:34:16] <mjw> theBohemian, http://spindazzle.org/gcjlib/ is what 
you are looking for I believe.
[2005-11-27 21:34:31] <guilhem> egonw_: no. I don't think so.
[2005-11-27 21:34:59] <mjw> egonw_, Do you have a line number for that 
ClassCastException?
[2005-11-27 21:35:02] <egonw_> guilhem: then I'll wait... (very busy with 
finishing PhD... so no time for diving into compiling stuff)
[2005-11-27 21:35:07] <egonw_> mjw: yes
[2005-11-27 21:35:17] <egonw_> java.lang.ClassCastException: can't cast 
`java/awt/image/BufferedImage' to `gnu/java/awt/peer/gtk/GtkImage'
[2005-11-27 21:35:17] <egonw_>    at 
gnu.java.awt.peer.gtk.GdkGraphics.drawImage (GdkGraphics.java:158)
[2005-11-27 21:35:46] <egonw_>    at 
gnu.java.awt.peer.gtk.GdkGraphics.drawImage (GdkGraphics.java:186)
[2005-11-27 21:35:46] <egonw_>    at org.jmol.viewer.Viewer.render1 
(Viewer.java:1597)
[2005-11-27 21:35:54] <egonw_> from then on it's Jmol code
[2005-11-27 21:36:35] <mjw> egonw_/Sven_M, then it looks like that is old 
code.
[2005-11-27 21:36:39] <Sven_M> Those line numbers don't match. That must be a 
very old version.
[2005-11-27 21:36:53] <mjw> The current drawImage code correctly checks before 
casting.
[2005-11-27 21:36:59] <Sven_M> Before I rewrote GtkImage entirely. Unless 
someone introduced one, there are no unchecked casts.
[2005-11-27 21:37:05] * egonw_ is not using CVS stuff
[2005-11-27 21:37:18] <egonw_> cp 0.18 I htink 
[2005-11-27 21:37:18] <egonw_> mom
[2005-11-27 21:37:26] <egonw_> 0.18-5ubuntu1
[2005-11-27 21:37:34] <mjw> At least use 0.19 :)
[2005-11-27 21:37:47] <mjw> 0.18 is so 2 months ago!
[2005-11-27 21:38:47] <mjw> And while you are at it, try cacao with that.
[2005-11-27 21:38:54] <egonw_> mjw: no kubuntu deb :(
[2005-11-27 21:38:55] <mjw> Should work out of the box with 0.19!
[2005-11-27 21:39:14] <mjw> tsss tsss tsss. enduser! :)
[2005-11-27 21:39:19] <Sven_M> mjw: GtkImage was rewritten by then though, I 
think.
[2005-11-27 21:39:35] <egonw_> mjw: :)
[2005-11-27 21:39:42] <mjw> Sven_M, Sure. But we don't know which kaffe 
version he is using.
[2005-11-27 21:39:55] <egonw_> 1.1.5-5ubuntu2
[2005-11-27 21:39:55] <lindi-> egonw_: even debian has classpath 0.19 :)
[2005-11-27 21:39:57] <mjw> Sven_M, kaffe still comes with its own copy of 
classpath...
[2005-11-27 21:40:02] <egonw_> sarge or sid?
[2005-11-27 21:40:08] <lindi-> egonw_: sid
[2005-11-27 21:40:18] <egonw_> mjw: I'm fairly OK with installing java stuff 
from sid
[2005-11-27 21:40:21] <mjw> It was released like 2 weeks ago!
[2005-11-27 21:40:25] <dalibor> 1.1.5? tststs. bad ubuntu! ;)
[2005-11-27 21:40:38] <egonw_> ok, hang on...
[2005-11-27 21:40:39] <dalibor> 1.1.6 is already uh ... two months old, I 
think.
[2005-11-27 21:40:40] <tashiro> egonw_: 0.19 was to late for breezy. dont know 
for kubuntu
[2005-11-27 21:40:41] <Sven_M> mjw: Ok, but anyway this stuff was fixed back 
in june already.
[2005-11-27 21:40:45] * egonw_ is updating Packages.gz for sid
[2005-11-27 21:40:45] <Sven_M> Early june at that.
[2005-11-27 21:41:24] <Sven_M> egonw_: Beware that the BufferedImage drawing 
code with the non-cairo peers is slow as heck. :)
[2005-11-27 21:41:34] <egonw_> Sven_M: yes, I noted that :)
[2005-11-27 21:41:36] <mjw> Sven_M, Kaffe 1.1.5 is from April!
[2005-11-27 21:41:40] <Sven_M> Slow with the cairo peers too.. just not 
super-slow :)
[2005-11-27 21:41:54] <egonw_> Sven_M: assuming jamvm was not using that... 
actually...
[2005-11-27 21:41:58] <Sven_M> mjw: Yeah, yeah.. I suppose we should be happy 
enough dalibor did a release at all ;)
[2005-11-27 21:42:07] <mjw> hehe
[2005-11-27 21:42:42] <Sven_M> egonw_: The whole GtkImage thing is just 
provisional.
[2005-11-27 21:42:50] <dalibor> dude, a release evry 6 months is about 10 
times faster than autoconf ;)
[2005-11-27 21:43:01] <egonw_> did I see correcly that work is ongoing on Qt 
peers?
[2005-11-27 21:43:15] * dalibor guesses autoconf 2.59 came out in 2001, or so
[2005-11-27 21:43:22] <Sven_M> egonw_: Kind of.
[2005-11-27 21:43:32] <egonw_> as in Java/Qt bindings... 
[2005-11-27 21:43:36] <Sven_M> egonw_: I wrote 'em. :) Haven't done much in 
the last few months though.
[2005-11-27 21:43:38] <egonw_> or Qt peers for Swing stuff
[2005-11-27 21:43:40] <egonw_> ?
[2005-11-27 21:43:52] <guilhem> egonw_: Qt peers for awt.
[2005-11-27 21:43:53] <Sven_M> egonw_: Right, Qt peers for AWT (Swing)
[2005-11-27 21:44:18] <Sven_M> I wouldn't hype the Swing though, since it does 
its own drawing and basically just uses AWT as a framebuffer.
[2005-11-27 21:44:59] <Sven_M> Which leads to the ironic result that if you've 
got a nice Qt theme, AWT looks better than Swing. When it's usually 
vice-versa.
[2005-11-27 21:45:13] * egonw_ is installing classpath 0.19 from debian sid
[2005-11-27 21:45:46] <egonw_> btw, I'm really happy with the Jmol renderer 
running...
[2005-11-27 21:45:53] <mjw> egonw_, And if you are into installing random 
weird shit then tashiro has some packages:
[2005-11-27 21:45:55] <mjw> 
http://vern.chem.tu-berlin.de/~stephan/software/upload/
[2005-11-27 21:46:03] <egonw_> someone told me (or at least I thought so) that 
BufferedImage was not working...
[2005-11-27 21:46:37] <dalibor> guilhem: oh, cool! nice proposal there on 
deflating the target layer!
[2005-11-27 21:46:52] * mjw should look up the marketing term for "random 
weird shit"...
[2005-11-27 21:47:11] <Sven_M> egonw_: BufferedImage is working in the sense 
that you can draw them, slowly.
[2005-11-27 21:47:23] <Sven_M> egonw_: It's not working in the sense that you 
can draw *to* them.
[2005-11-27 21:47:33] <egonw_> mmm...
[2005-11-27 21:47:47] * egonw_ needs to study the Jmol code again...
[2005-11-27 21:48:02] <egonw_> I thought Jmol was drawing bits in the 
BufferedImage...
[2005-11-27 21:48:03] <Sven_M> So if you're using them for back-buffering, 
well.. it ain't going to work, yet.
[2005-11-27 21:48:27] <Sven_M> egonw_: Drawing bits works, I guess. But 
getting a Graphics object for it doesn't.
[2005-11-27 21:48:55] <egonw_> I have vague feeling that I'm starting to 
understand...
[2005-11-27 21:49:44] <egonw_> that's fine...
[2005-11-27 21:49:50] <egonw_> Jmol is not using Java2D
[2005-11-27 21:51:24] <Sven_M> egonw_: 1.1-version AWT only?
[2005-11-27 21:51:34] <egonw_> yes
[2005-11-27 21:51:41] * mjw still demands a screenshot!
[2005-11-27 21:51:46] <egonw_> only way to get it working in many browsers...
[2005-11-27 21:51:47] <Sven_M> Where'd the BufferedImage come from?
[2005-11-27 21:51:51] <egonw_> mjw: yes, yes... 
[2005-11-27 21:51:53] <egonw_> hang on...
[2005-11-27 21:51:55] <egonw_> working on it
[2005-11-27 21:52:18] <Sven_M> mjw: http://www.qc.physto.se/~sven/bevel.png
[2005-11-27 21:53:43] <mjw> Sven_M, Heay. Is that what I think it is?
[2005-11-27 21:54:52] <Sven_M> mjw: Backward 'l's!
[2005-11-27 21:54:58] <mjw> :)
[2005-11-27 21:55:32] <mjw> had hoped two it was 2 BasicStrokes munged 
together.
[2005-11-27 21:56:59] <theBohemian> Sven_M: you're right. I was wrong
[2005-11-27 21:57:18] <theBohemian> Sven_M: mjw fixed the ClasscastException 
in the GdkPixBufDecoder
[2005-11-27 21:57:54] <mjw> O right! I remember that one. That was for the 
imageio streams.
[2005-11-27 21:58:17] <Sven_M> theBohemian: Good :) I distinctly remember 
cleaning up all GtkImage casts back then, so I'd hate to have had a 
regression there.
[2005-11-27 21:59:45] <guilhem> bye all !
[2005-11-27 21:59:49] <-- guilhem has left this server. ("Download Gaim: 
http://gaim.sourceforge.net/";)
[2005-11-27 22:03:23] <theBohemian> mjw: I know the XMLEncoder code is a bad 
shape
[2005-11-27 22:03:51] <theBohemian> mjw: but 'they' asked for it so dearly
[2005-11-27 22:04:14] <mjw> theBohemian, hehe. You cannot keep blaming "them" 
for everything :)
[2005-11-27 22:04:23] <egonw_> mjw: your screenshot -> 
http://chem-bla-ics.blogspot.com/2005/11/open-source-swing-jmol-renderer-runs.html
[2005-11-27 22:04:25] <mjw> theBohemian, There were certainly some good parts 
in it.
[2005-11-27 22:05:14] <theBohemian> mjw: I found no time to continue the 
implementation because of my job. Its like in this stallman text, I sell my 
priority list ;)
[2005-11-27 22:05:19] <Sven_M> Cool. Water.
[2005-11-27 22:05:26] <theBohemian> mjw: ok, just kidding.
[2005-11-27 22:06:03] <theBohemian> mjw: anyway I asked about finishing the 
encoder as part of my job and got an ok about this.
[2005-11-27 22:06:49] <mjw> Very nice screenshot.
[2005-11-27 22:07:08] <mjw> I see on the mailinglist we have another user 
complaining about slowness.
[2005-11-27 22:07:10] <mjw> hmmmm
[2005-11-27 22:07:20] <mjw> theBohemian, Wow! That is so nice!
[2005-11-27 22:07:40] <mjw> theBohemian, And please do feel free to commit 
those parts you are happy about.
[2005-11-27 22:08:05] <mjw> theBohemian, And even the bad parts if you can add 
some documentation on how you would like to see it improved/redesigned.
[2005-11-27 22:08:32] <egonw_> mjw: I would have love to demo a protein... 
[2005-11-27 22:08:37] <egonw_> actually...
[2005-11-27 22:08:45] <egonw_> that might not be that much slower...
[2005-11-27 22:08:54] <egonw_> it's rendering the BufferedImage that is slow, 
correct?
[2005-11-27 22:09:28] <Sven_M> egonw_: Shouldn't be any BufferedImage involved 
though unless you're using Graphics2D.
[2005-11-27 22:09:40] <egonw_> Sven_M: hang on...
[2005-11-27 22:10:01] <mjw> I would say, compile to native and use oprofile on 
it! :)
[2005-11-27 22:10:04] <Sven_M> Otherwise it should use GtkImage and then it 
draws to an X pixmap. Which means blitting it is about as fast as it can get.
[2005-11-27 22:10:29] <Sven_M> Or rather, GtkImage = X Pixmap
[2005-11-27 22:10:39] <theBohemian> mjw: yep. I separate the doc fixes and 
such tommorow and send them in.
[2005-11-27 22:10:52] * theBohemian not feeling well today and need some 
sleep.
[2005-11-27 22:10:57] <theBohemian> cya
[2005-11-27 22:11:03] <egonw_> Sven_M: could you have a look at these bits of

[2005-11-27 22:17:28] <grey_gandalf> but no exceptions
[2005-11-27 22:17:59] <grey_gandalf> (wrongly: 1. wrong size, 2. it has no 
hide arrows)
[2005-11-27 22:19:46] <mjw> grey_gandalf, Hi Riccardo
[2005-11-27 22:20:08] <egonw_> Sven_M: forcing the AWT version breaks it :(
[2005-11-27 22:20:09] <Sven_M> egonw_: The Swing3D thing uses BufferedImage I 
see, so yeah, that won't work as well.
[2005-11-27 22:20:30] <egonw_> Sven_M: but you've seen the screenshot ?!?!
[2005-11-27 22:20:31] <grey_gandalf> hey sven !
[2005-11-27 22:20:39] <Sven_M> 'lo grey_gandalf
[2005-11-27 22:20:42] <grey_gandalf> mjw when I click to open an inspector 
panel I get
[2005-11-27 22:20:43] <grey_gandalf> 
http://rafb.net/paste/results/Rbv6y257.html
[2005-11-27 22:21:16] <grey_gandalf> if I try to resizze the pane, the drag 
line gets drawn in black, I start dragging but when I relese.. nothing 
happens, the black line remains
[2005-11-27 22:21:16] <mjw> grey_gandalf, This is with kaffe CVS right?
[2005-11-27 22:21:34] <grey_gandalf> mjw: yes, fresh fresh... thus I tihnk 
quite up-tpo-date CP
[2005-11-27 22:21:44] <grey_gandalf> guilhem synced this afternoon
[2005-11-27 22:22:03] <grey_gandalf> mjw: if you want to try the application 
on gcj or something like that...
[2005-11-27 22:22:22] <egonw_> Sven_M: the swing one works, the AWT does 
not... 
[2005-11-27 22:22:41] <Sven_M> egonw_: Wacky.
[2005-11-27 22:23:00] <Sven_M> egonw_: Ok, are you using Graphics2D/Cairo or 
not?
[2005-11-27 22:23:08] <egonw_> jamvm 1.3.3
[2005-11-27 22:23:12] <Sven_M> egonw_: And what isn't working about the AWT 
version?
[2005-11-27 22:23:26] <egonw_> I get a grey content instead of the black + 
water
[2005-11-27 22:23:29] <mjw> grey_gandalf, Looking at the source of 
ScrollPaneLayout and Container. Let me think.
[2005-11-27 22:23:31] <Sven_M> egonw_: Well, ok, but which classpath and did 
you build it with Graphics2D support?
[2005-11-27 22:23:42] <egonw_> debian sid packages 
[2005-11-27 22:23:46] <egonw_> classpath 0.19
[2005-11-27 22:23:48] <egonw_> -2
[2005-11-27 22:24:46] <Sven_M> egonw_: Ok, hmm.. uh, could you tell me what 
Component.createImage(int, int) returns?
[2005-11-27 22:25:02] <egonw_> class type?
[2005-11-27 22:26:13] <egonw_> hang on
[2005-11-27 22:28:19] <egonw_> Sven_M: gnu.java.awt.peer.gtk.GtkImage
[2005-11-27 22:29:53] <Sven_M> egonw_: Ok. That's good. Hmm. You know what it 
*could* be? Could be that you're assuming that the native pixel format is 
32-bit RGB, when it tends to default to 32-bit RGBA with GtkImage (IIRC), 
meaning you've got a zero alpha channel --> the thing is being drawn 
transparently!
[2005-11-27 22:30:01] <mjw> grey_gandalf, Interesting. Still looking what this 
should actually do.
[2005-11-27 22:30:07] <grey_gandalf> :)
[2005-11-27 22:30:09] <mjw> grey_gandalf, Well done. You found a bug! :)
[2005-11-27 22:30:19] <egonw_> Sven_M: OK, how to test that?
[2005-11-27 22:30:37] <grey_gandalf> mjw: that is why people fear me :)
[2005-11-27 22:30:39] <egonw_> Sven_M: or fix that...
[2005-11-27 22:32:11] <Sven_M> egonw_: Good question. Hmm... Easy. Dump the 
first few ints in pBuffer there.
[2005-11-27 22:32:47] <Sven_M> egonw_: Should be 0xFF000000 (or 0x000000FF) 
for black and not 0.
[2005-11-27 22:33:01] <egonw_> ok, where do I do that?
[2005-11-27 22:33:10] * egonw_ is looking... mom
[2005-11-27 22:33:25] <Sven_M> egonw_: Well, at some spot when you know the 
image is drawn.. :)
[2005-11-27 22:33:36] <grey_gandalf> mjw: were you able to find a fix too? :)
[2005-11-27 22:34:05] <mjw> grey_gandalf, I am not sure.
[2005-11-27 22:34:13] <egonw_> ok, I see something promosing: 
ic.setPixels( bla bla, pBuffer, bla bla)
[2005-11-27 22:34:29] <mjw> grey_gandalf, So you add this thing to the 
ScrollPaneLayout.
[2005-11-27 22:34:33] <Sven_M> egonw_: Yeah, maybe in that startProduction 
method.
[2005-11-27 22:34:51] <mjw> grey_gandalf, I assume you expect it to show up in 
the main viewport.
[2005-11-27 22:34:54] <Sven_M> it should be called every time the image is 
recreated/redrawn
[2005-11-27 22:35:32] <egonw_> 4 bytes enough?
[2005-11-27 22:36:07] <grey_gandalf> mjw: let me check the line
[2005-11-27 22:36:15] <grey_gandalf> I add many scoll things :)
[2005-11-27 22:36:30] <egonw_> Sven_M: all first four is zero...
[2005-11-27 22:36:31] <Sven_M> egonw_: If the top-left corner is black, then 
yes :)
[2005-11-27 22:36:35] <egonw_> that's what you expected right?
[2005-11-27 22:36:51] <Sven_M> egonw_: Well, it'd fit with theory above.
[2005-11-27 22:36:52] <egonw_> that's ... that means transparent, correct?
[2005-11-27 22:37:01] <Sven_M> egonw_: Right.
[2005-11-27 22:37:08] <egonw_> OK, will relay this to the rendering engine 
developer...
[2005-11-27 22:37:08] <Sven_M> I think.
[2005-11-27 22:37:25] <egonw_> OK, and using AWT would be faster, correct too?
[2005-11-27 22:37:26] <Sven_M> Yup, we default to RGBA.
[2005-11-27 22:37:38] <-- rabbit_ has left this server. (Connection timed out)
[2005-11-27 22:37:46] <grey_gandalf> mjw: intrestingly, it is some code that 
currently doesn't work very well
[2005-11-27 22:37:54] <Sven_M> I'm pretty sure the JDK doesn't though.
[2005-11-27 22:38:09] <Sven_M> Or is it the other way around..
[2005-11-27 22:39:03] <Sven_M> egonw_: Hmm.. try a workaround.
[2005-11-27 22:40:25] <egonw_> suggestions?
[2005-11-27 22:40:35] <Sven_M> egonw_: Add to the startProduction() method 
something a la for(int i=0;i<pBuffer.length;i++)pBuffer[i] |= 0xFF000000;
[2005-11-27 22:40:48] <Sven_M> So you set the alpha channel to opaque.
[2005-11-27 22:41:00] <egonw_> Sven_M: ack, hang on
[2005-11-27 22:44:04] <egonw_> Sven_M: OK, I now have a black background
[2005-11-27 22:44:57] <egonw_> but the water is gone
[2005-11-27 22:45:43] <Sven_M> Huh.
[2005-11-27 22:46:05] <Sven_M> egonw_: Well that's pretty weird! :)
[2005-11-27 22:47:38] <egonw_> but not something Miguel will not understand...
[2005-11-27 22:47:46] <egonw_> do you want to be cc-ed?
[2005-11-27 22:48:16] <Sven_M> Hmm.. this might be your problem, actually: 
colorModelRGB = ColorModel.getRGBdefault();
[2005-11-27 22:48:22] <Sven_M> Or maybe it's our problem.
[2005-11-27 22:48:29] <Sven_M> But I think it's yours.
[2005-11-27 22:48:33] <egonw_> :)
[2005-11-27 22:48:47] <Sven_M> ColorModel.getRGBdefault() is 32-bit RGB.
[2005-11-27 22:48:55] <egonw_> OK, I'll email Miguel... he's far more 
knowlegdable in these matters than I am...
[2005-11-27 22:49:04] <egonw_> Sven_M: makes sense...
[2005-11-27 22:49:10] <egonw_> is there a RGBA default too?
[2005-11-27 22:49:11] <Sven_M> But it's NOT necessarily the default colorModel 
used by Component.createImage()
[2005-11-27 22:49:43] <egonw_> do you have a suggestion?
[2005-11-27 22:49:43] <Sven_M> Which is returned by Toolkit.getColorModel().
[2005-11-27 22:49:53] <egonw_> OK
[2005-11-27 22:49:56] <egonw_> mom, will try
[2005-11-27 22:50:14] <Sven_M> egonw_: Yeah, so try changing that to 
Toolkit.getDefaultToolkit().getColorModel().
[2005-11-27 22:50:23] <Sven_M> I'm assuming you *use* this later :)
[2005-11-27 22:50:29] <egonw_> :)
[2005-11-27 22:51:08] <Sven_M> Could be that you're drawing a transparent 
water onto a nontransparent black background or something.
[2005-11-27 22:51:36] <egonw_> yeah...
[2005-11-27 22:51:43] <egonw_> recompiling...
[2005-11-27 22:52:20] <egonw_> does not do anything...
[2005-11-27 22:52:39] <egonw_> it is used though...
[2005-11-27 22:52:44] <egonw_> in the setPixels call...
[2005-11-27 22:56:12] <Sven_M> egonw_: Oh right.
[2005-11-27 22:57:21] <-- man-di2 has left this server. ("Verlassend")
[2005-11-27 22:57:25] <Sven_M> That shouldn't matter though, I mean if we're 
setting the alpha channel to 255.
[2005-11-27 22:57:36] <egonw_> indeed...
[2005-11-27 22:57:51] <egonw_> I'm pretty sure Miguel will understand what is 
going on...
[2005-11-27 22:58:05] <egonw_> Sven_M: if you message me your email address, 
I'll cc you
[2005-11-27 22:58:13] <Sven_M> egonw_: [EMAIL PROTECTED]
[2005-11-27 22:59:27] <Sven_M> egonw_: BTW, does Jmol handle Molden frequency 
files?
[2005-11-27 22:59:43] <egonw_> send a file and then we can add it
[2005-11-27 23:00:04] <egonw_> (assuming that they store the frequencies as 
vectors)
