[JAVA2D] Problems with BufferedImage.createGraphics
Dear fellows, I have a strange Problem with creation of Graphics2D for an BufferedImage. Code fragment: BufferedImage bufferedImage1; Graphics2D g2d; int width = 1000; // absolute pixels int height = 800; // absolute pixels // Create a buffered image in which to draw bufferedImage1 = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); // Create a graphics contents on the buffered image g2d = bufferedImage1.createGraphics(); When using JBuilder 8 Personal Edition with JDK 1.4.1-b21 under Windows98, all works fine and further use of graphics commands and final call of ImageIO.write(bufferedImage1, png, new File(fileName4pic)) behave as expected. When using the same JBuilder 8 Personal Edition with the same JDK 1.4.1-b21 under Windows2000, the following surprising error message is displayed: java.lang.NoClassDefFoundError at sun.java2d.Disposer.addRecord(Disposer.java:68) at sun.awt.image.BufImgSurfaceData.initRaster(Native Method) at sun.awt.image.BufImgSurfaceData.createDataIC(BufImgSurfaceData.java:226) at sun.awt.image.BufImgSurfaceData.createData(BufImgSurfaceData.java:69) at sun.java2d.SunGraphicsEnvironment.createGraphics(SunGraphicsEnvironment.java:266) at java.awt.image.BufferedImage.createGraphics(BufferedImage.java:1043) at markov8.TestBufferedImage.main(TestBufferedImage.java:27) Exception in thread main When using the JBuilder 9 Personal Edition with the same JDK 1.4.1_02-b06 under Red Hat Linux 9, the following surprising error message is displayed: Exception in thread main java.lang.NoClassDefFoundError at sun.java2d.Disposer.addRecord(Disposer.java:68) at sun.awt.image.BufImgSurfaceData.initRaster(Native Method) at sun.awt.image.BufImgSurfaceData.createDataIC(BufImgSurfaceData.java:238) at sun.awt.image.BufImgSurfaceData.createData(BufImgSurfaceData.java:73) at sun.java2d.SunGraphicsEnvironment.createGraphics(SunGraphicsEnvironment.java:266) at java.awt.image.BufferedImage.createGraphics(BufferedImage.java:1043) at markov8.TestBufferedImage.main(TestBufferedImage.java:27) What the hell is going on here Aufnehmen, abschicken, nah sein - So einfach ist WEB.DE Video-Mail: http://freemail.web.de/?mc=021200 === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message signoff JAVA2D-INTEREST.

[JAVA2D] disappearing borders
I have a small problem that seems to be related to the version of jdk being used. I have an image manipulation application which contains two canvases for viewing images. At program startup both canvases are assigned and given etched borders. My program has a function that allows a user to annotate an image by drawing crosses on its graphical context. When using the jdk1.4, the first time an annotation is painted through a mouseclick, the borders disappear for good. This problem does not occur with jdk1.3. If anyone can help me to figure why this is happening or how to resolve the problem so everything works with the latest jdk, it would be much appreciated.

Re: [JAVA2D] Problems with BufferedImage.createGraphics
Hi Sven, do you see these problems when the application is run standalone (outside of JBuilder)? It looks like JBuilder does some mangling of the bootclasspath when it starts the app from IDE.
