Supporting 64bit is not very important when most of your code is in Java. But Teppefall does have around 300kb of C++ that needs to be ported. And the process is something like this.

• Install crazy big Windows SDK and Visual Studio on Windows 7.


• Realize that the Windows documentation is wrong when it comes to "vcvarsall.bat amd64".


• Dig around for a while.


• Find the correct BAT based configuration files and drag them into the application menu.


• Create custom makefiles.


• Scratch your head as Microsoft uses the suffix "32" in paths and library names everywhere.


• More mind numbingly boring rewriting of makefiles.


• Everything compiles, but Winsock related code is broken. Might be configuration. Might be worse.


• Realize that 64bit JRE writes a registry JVM value that points to a non-existent file. My fault ?


• But the code supports that, so just use TEPPEFALL_JVM variable.


• Success!

All software except the SDK has been updated. Tons of minor fixes and the compile target is now 1.5. Yeah, yeah, I know. I needed to support OS X Panther.

Also releasing some new software. VmPrefetch is a simple VM prefetcher that should be run on startup. Nothing fancy yet, but I'm reading up on the latest instrumentation API's, so it might get smarter in the future. Currently this has a high snake oil factor, but I'm too arrogant to care. This is still not a 1.0, so user beware.

Create a shortcut and move it into one of these folders. Or just run it from the desktop.

Windows Vista
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup
Windows XP
C:\Documents And Settings\All Users\Start Menu\Programs\Startup
OS X
Right click on icon and select “Open at Login”.

LCDTest is an updated version of the demo application that is included in the SDK. Very few people will find this too exciting.

Here is a new demo that showcases Teppefall 2D. It uses the same layout system as the other applets.

2D viewport
Vertically adjusting viewport.

Controls:
CTRL/Command + Up,Down,Left,Right.
CTRL + ALT + Up,Down,Left,Right.
CTRL + Enter (or doubleclick).
CTRL + Backspace.
Or just use the mouse, scroll wheel and CTRL.

Safari users can not use CTRL + Left,Right because Safari denies access to this key combination. Goldensection is based on a DrawBot example.

Java Applets.

beta.fx.layer

beta.fx.shapeddemo2d

beta.fx.textlayout

beta.fx.cover (broken on Linux)

beta.fx.oddshape

beta.fx.goldensection

I am not sure if people are aware of this, but you can run Teppefall FX scripts within Teppefall Layout.

Also, here is Colorspace in Titanium White LAF.

Here are the changes.

Teppefall Layout 3.6
Teppefall FX 3.6
Teppefall Colorspace 1.9
Teppefall SDK (Darkstar) 20080303

- CMD and SH files have the correct Darkstar parameters.
- Added a button that displays the pop-up menu.

- Linux executables.
- Linux shell script updates.
- Windows command script cleanup.
- Executables now treat all applications the same way.

Anyone who gets the stupid java.lang.AbstractMethodError exception when running a Darkstar FX script (the UI falls apart) must change D2DAdapter to D2DRenderer. Partially implemented abstract classes no longer work under Rhino 1.6.

Also, if you run into Javascript method overloading problems, like float versus int etc, then the solution is explicit type casting.

function fixColor(r, g, b) {
return new Color["(int,int,int)"](r,g,b)
}

I have been playing a little with Kirill's SVG to Java transcoder and then manually converting the Java code into Javascript based Darkstar FX renderer's. Very tedious, but good fun nevertheless. I had less success with the SVG to JavaFX converter, but that might just be a case of me using old software.

There are at least four SVG importer pipelines available for Java, so there seems to be some interest in this.

• Batik


• Kirill Grouchnikov - SVG to Java transcoder (based on Batik)


• Chris Oliver - SVG to JavaFX transcoder


• Jasper Potts - SVGShapeExtractor

The memory leak seems to affect Windows XP as well, so I can only assume that this is a problem on all platforms. You are only affected if you run under -Dteppefall.chrome=false and you can probably stop the problem by setting -Dteppefall.cursor-monitor=false.

Example:

java
-Dteppefall.cursor-monitor=false
-Dteppefall.chrome=false
-Dteppefall.override=true
-Dswing.defaultlaf=com.teppefall.ds.look.TitaniumLAF
-jar darkstarlayout.jar

Darkstar 2D's CompositeQuickTime.createImageFromQT should work on OS X and you end up with a apple.awt.OSXImage. Fun fact: searching for apple.awt.OSXImage on Google gives me 10 hits.

Wow.. written by a high school senior. The mask and sprite code is really cool. So I made a Javascript “mashup” in Darkstar FX.

One thing that is strange. My color picker (Colorspace) reports that the green in the Mario tile is #008500 in Firefox but #007300 when I paint the same image in Java 2D or open the file in Photoshop.

New features:

Colorspace supports the scroll wheel. One NPE fixed. Both fixes by Luan. Decimal values are written to standard output when the decimal check box is selected. 200-500ms shaved off About dialog launch. Colorspace no longer runs under a security policy since it causes to many problems on OS X.

Darkstar applications now have focus aware menus under Titanium LAF. A feature from the stone age. Just use com.teppefall.ds.Application in the same way as before. This means that the foreground color of your menu goes dark (under Titanium) when the JFrame loses focus.

The DSR executable supports the -Xchrome parameter. This turns on the native chrome and is the same as -Dteppefall.chrome=true.

DSR can launch multiple applications at the same time. Just add a comma separator between class names. A word of warning though. Running threads might block the shutdown process, so closing down resources on application exit is paramount. Note that DSR today has a very high probability of not closing down properly.

Other issues:

If Darkstar FX is unable to create HTML and thumbnails you should try the -Xinsecure parameter. FX and Layout run under security managers and can fail if the policy file is not perfect. Strange problems when running under DSR might also be a result of the security policy.

Colorspace 1.3, Fabric 2.8 and Surface 2.8 is available in the data folder. I will update the download page tomorrow. Colorspace now supports the taskbar, Fabric is less retarded and Surface has a new loader icon + hex color to STDOUT fix.
