+ * + * The bug is OpenJDK specific. This program runs with Oracle JDK + * just fine (it still does not do anything sensible, but it does + * not fail with a RasterFormatException, either). + * + *

+ * + * 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: + * + *

+ * + * This calls for a sub-raster with bounds that fall outside the + * original raster, and therefore the 'createWritableChild' method + * correctly throws 'RasterFormatException'. + * + *

+ * + * 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); + try { + g2d.fill(gp); + } catch (RasterFormatException rfe) { + System.out.println("Test failed"); + throw new RuntimeException("xmax/ymax rounding cause RasterFormatException"); + } + g2d.dispose(); + System.out.println("Test passed"); + } + + // === 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 + } + } + } +}
