http://issues.apache.org/bugzilla/show_bug.cgi?id=35683 Summary: ArrayIndexOutOfBoundsException in IndexImage.getIndexedImage() method Product: Batik Version: 1.5 Platform: PC OS/Version: Windows XP Status: NEW Severity: normal Priority: P2 Component: Utilities AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] I tried to get Indexed image from a *.png image and obtained the following exception: java.lang.ArrayIndexOutOfBoundsException: -7 at org.apache.batik.ext.awt.image.rendered.IndexImage$Cube.splitChannel (Unknown Source) at org.apache.batik.ext.awt.image.rendered.IndexImage$Cube.split (Unknown Source) at org.apache.batik.ext.awt.image.rendered.IndexImage.getIndexedImage (Unknown Source) at ImageUtilities.encodeImageTo8Bit(ImageUtilities.java:49) at ImageTest.test(ImageTest.java:28) at ImageTest.main(ImageTest.java:37) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:78) Exception in thread "main" First of all I created a BufferedImage object from Image object. I did it as follows: public static BufferedImage BufferedFromImage(Image i) { if (i == null) throw new NullPointerException(); Panel p = new Panel(); if (i instanceof BufferedImage) return (BufferedImage) i; i = new ImageIcon(i).getImage(); int type = (hasAlpha(i)) ? BufferedImage.TYPE_INT_ARGB : BufferedImage.TYPE_INT_RGB; BufferedImage buf = new BufferedImage(i.getWidth(p), i.getHeight(p), type); Graphics2D g = (Graphics2D)buf.getGraphics(); g.drawImage(i, 0, 0, p); g.dispose(); return buf; } private static boolean hasAlpha(Image i) { if (i == null) throw new NullPointerException(); if (i instanceof BufferedImage) return ((BufferedImage) i).getColorModel().hasAlpha(); PixelGrabber grab = new PixelGrabber(i, 0, 0, 1, 1, false); try { grab.grabPixels(); } catch (InterruptedException ex) { } ColorModel cm = grab.getColorModel(); return cm.hasAlpha(); } I attached a picture which results in exception. Note , that I tried to process other images and all worked properly except this image. I investigated source and found that this exception is thrown due to negative array index value. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
