Jan Tošovský commented on BATIK-1106:
-------------------------------------
I've finally tracked down the cause: ColorSpace. Currently it is set to
CS_LINEAR_RGB. You can easily test the behavior using this snippet. It fails
with the same error message as originally reported. If the color space is
changed to ColorSpace.CS_sRGB, the conversion runs smoothly.
ColorModel linearRGBColorModel = new
DirectColorModel(ColorSpace.getInstance(ColorSpace.CS_LINEAR_RGB), 32,
0xff0000, 0xff00, 0xff, 0xff000000, true, DataBuffer.TYPE_INT);
WritableRaster srcRaster =
linearRGBColorModel.createCompatibleWritableRaster(100, 100);
WritableRaster dstRaster =
linearRGBColorModel.createCompatibleWritableRaster(200, 200);
BufferedImage srcImage = new BufferedImage(linearRGBColorModel,
srcRaster, false, null);
BufferedImage dstImage = new BufferedImage(linearRGBColorModel,
dstRaster, false, null);
AffineTransform aff = new AffineTransform();
aff.scale(2.0, 2.0);
AffineTransformOp op = new AffineTransformOp(aff, null);
op.filter(srcImage, dstImage);
I've tried to override the ColorSpace in AffineRed.java by injecting the
following code:
ColorModel sRGBColorModel = new DirectColorModel(ColorSpace.getInstance
(ColorSpace.CS_sRGB), 32,
0xff0000, 0xff00, 0xff, 0xff000000, true,
DataBuffer.TYPE_INT);
WritableRaster srcRaster =
sRGBColorModel.createCompatibleWritableRaster(srcBI.getWidth(),
srcBI.getHeight());
WritableRaster myRaster =
sRGBColorModel.createCompatibleWritableRaster(myBI.getWidth(),
myBI.getHeight());
BufferedImage srcBIx = new BufferedImage(sRGBColorModel, srcRaster,
false, null);
BufferedImage myBIx = new BufferedImage(sRGBColorModel, myRaster,
false, null);
try {
ImageIO.write(srcBI, "PNG", new File("D:/srcBI.png"));
ImageIO.write(myBI, "PNG", new File("D:/myBI.png"));
ImageIO.write(srcBIx, "PNG", new File("D:/srcBIx.png"));
ImageIO.write(myBIx, "PNG", new File("D:/myBIx.png"));
} catch (IOException e) {
System.out.println(e.getMessage());
}
op.filter(srcBIx, myBIx);
It runs, but that blurred shadow disappear from the output :-(
