http://mail.openjdk.java.net/pipermail/2d-dev/2014-June/004652.html reports the following OpenJDK only bug :- > * The bug is related to sun.java2d.pisces.PiscesCache constructor > * that accepts '(int minx,int miny,int maxx,int maxy)' arguments: > * the internal 'bboxX1' and 'bboxY1' are set to values one greater > * than given maximum X and Y values. >I think so because this is a Pure Java issue, it seems to be a simple > "off by one pixel" kind of error, and because all the other pipe > implementations except 'AAShapePipe' seem to work, and also because > corresponding OracleJDK implementation works. The test program supplied demonstrates the exception Exception in thread "main" java.awt.image.RasterFormatException: (x + width) is outside raster at sun.awt.image.IntegerInterleavedRaster.createWritableChild(IntegerInterleavedRaster.java:467) at sun.awt.image.IntegerInterleavedRaster.createChild(IntegerInterleavedRaster.java:514) at sun.java2d.pipe.GeneralCompositePipe.renderPathTile(GeneralCompositePipe.java:106) at sun.java2d.pipe.AAShapePipe.renderTiles(AAShapePipe.java:201) at sun.java2d.pipe.AAShapePipe.renderPath(AAShapePipe.java:159) at sun.java2d.pipe.AAShapePipe.fill(AAShapePipe.java:68) at sun.java2d.pipe.PixelToParallelogramConverter.fill(PixelToParallelogramConverter.java:164) at sun.java2d.pipe.ValidatePipe.fill(ValidatePipe.java:160) at sun.java2d.SunGraphics2D.fill(SunGraphics2D.java:2491) at OpenJDKFillBug.main(OpenJDKFillBug.java:121) import java.awt.Color; import java.awt.Composite; import java.awt.CompositeContext; import java.awt.Graphics2D; import java.awt.RenderingHints; import java.awt.geom.AffineTransform; import java.awt.geom.GeneralPath; import java.awt.image.BufferedImage; import java.awt.image.ColorModel; import java.awt.image.Raster; import java.awt.image.WritableRaster; /** * Test program that demonstrates a bug in OpenJDK 1.7.0.60 (and * probably in all other OpenJDK versions, too). * * @see #main(String[]) * * @author Rami H����nninen */ public class OpenJDKFillBug { /** * Test program that demonstrates a bug in OpenJDK 1.7.0.60 (and * probably in all other OpenJDK versions, too). To see the bug, simply run * the 'main' program with OpenJDK.

This program runs with Oracle JDK * just fine (it still does not do anything sensible, but it does * not fail with a RasterFormatException, either). * * <P> * * The bug is related to sun.java2d.pisces.PiscesCache constructor * that accepts '(int minx,int miny,int maxx,int maxy)' arguments: * the internal 'bboxX1' and 'bboxY1' are set to values one greater * than given maximum X and Y values. Those maximum values are then * later used in AAShapePipe' class 'renderTiles' method, where a * Y/X loop eventually calls 'GeneralCompositePipe' class * 'renderPathTile' method. In that method, the operation will * eventually call 'IntegerInterleavedRaster' class * 'createWritableChild' method with arguments: * * <UL> * <LI>x=800 * <LI>y=0 * <LI>width=2 (this value is too high: should be 1) * <LI>height=32 * <LI>x0=0 * <LI>y0=0 * <LI>bandList[]=null * </UL> * * This calls for a sub-raster with bounds that fall outside the * original raster, and therefore the 'createWritableChild' method * correctly throws 'RasterFormatException'. * * <P> * * The bug is closely related to the use of a custom Composite * implementation, which are quite rare. The application where this * bug was first detected implements a high-quality PDF rendering * engine that needs custom Composite operations to properly * implement PDF advanced color blending and masking operators. */ public static void main(String args[]) { BufferedImage bi = new BufferedImage(801,1202,BufferedImage.TYPE_INT_ARGB); Graphics2D g2d = bi.createGraphics(); GeneralPath gp = new GeneralPath(); AffineTransform m = new AffineTransform(2.483489907915543, 0.0, 0.0, -2.4844977263331955, 0.0, 1202.0); Composite c = new CustomComposite(); gp.moveTo(-4.511, -14.349); gp.lineTo(327.489, -14.349); gp.lineTo(327.489, 494.15); gp.lineTo(-4.511, 494.15); gp.closePath(); g2d.setRenderingHint(RenderingHints.KEY_ALPHA_INTERPOLATION, RenderingHints.VALUE_ALPHA_INTERPOLATION_QUALITY); g2d.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); g2d.setRenderingHint(RenderingHints.KEY_COLOR_RENDERING, RenderingHints.VALUE_COLOR_RENDER_QUALITY); g2d.setRenderingHint(RenderingHints.KEY_TEXT_LCD_CONTRAST, Integer.valueOf(140)); g2d.setRenderingHint(RenderingHints.KEY_DITHERING, RenderingHints.VALUE_DITHER_ENABLE); g2d.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_DEFAULT); g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); g2d.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_NORMALIZE); g2d.setPaint(Color.red); g2d.setComposite(c); g2d.setTransform(m); g2d.fill(gp); g2d.dispose(); } // === CustomComposite === /** * Dummy custom Composite implementation. */ public static class CustomComposite implements Composite { @Override public CompositeContext createContext(ColorModel srcColorModel, ColorModel dstColorModel, RenderingHints hints) { return new CustomCompositeContext(); } // === CustomCompositeContext === /** * Dummy custom CompositeContext implementation. */ public static class CustomCompositeContext implements CompositeContext { @Override public void dispose() { // NOP } @Override public void compose(Raster src,Raster dstIn,WritableRaster dstOut) { // NOP } } } }
