read buffered image

[Ryan Jones]

I am attempting to save a jpg image of a plot. The following code is how I thought it should work after doing a bit of research. I have also tried every combination to try and use the correct GL

AWTGLReadBufferUtil readutil = new AWTGLReadBufferUtil (GLProfile.get(GLProfile.GL2GL3),false);

           BufferedImage tScreenshot = readutil.readPixelsToBufferedImage(canvas.getGLDrawable().getGL(),true);

            File tScreenCaptureImageFile = new File("test.jpg"); 

            try { 

                ImageIO.write(tScreenshot, "jpg", tScreenCaptureImageFile);

            } catch (IOException ex) {

                Logger.getLogger(SPDisplay.class.getName()).log(Level.SEVERE, null, ex);

            }

All I get is a black image. Any suggestions?

Nevermind,

I found your example screenshotutil.

Great! Glad the example was helpful.

The next minor release (2.1.2), which should happen sometime this week, includes cleanup and improvements to the screenshot functionality. So the code will be different in that version. The ScreenshotExample class will be updated to demonstrate these changes.
