Drawing an image with a transform fails

Name: gm110360 Date: 04/30/2003


FULL PRODUCT VERSION :
java version "1.4.2-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-beta-b19)
Java HotSpot(TM) Client VM (build 1.4.2-beta-b19, mixed mode)

FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
AffineTransformOp.filter throws a java.awt.image.ImagingOpException: Unable to
tranform src image when a PixelInterleavedSampleModel is used.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Set up a BufferedImage using the PixelInterleavedSampleModel

final ComponentSampleModel pism = new PixelInterleavedSampleModel
(DataBuffer.TYPE_FLOAT,width,height, bands,width * bands, new int[]{ red,
green, blue} );

WritableRaster wr = Raster.createWritableRaster(pism, db, null);

        ComponentColorModel ccm = new ComponentColorModel(
        ColorSpace.getInstance(ColorSpace.CS_sRGB),
        (int[])null,false, false, ColorModel.OPAQUE,
        DataBuffer.TYPE_FLOAT);

        BufferedImage bi = new BufferedImage( ccm, wr, false, null);


2. Apply a scale transform other than 1.0 to the Graphics

3. draw the image to the Graphics



EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected:
   A transformed version of the image to be drawn on screen

Actual:
   Exception
Paint being called

CUSTOMER SUBMITTED WORKAROUND :
draw the BufferedImage into a buffered image of type ARGB then perform the
affine transform. THIS OPERATION WASTES RESOURCES BY PERFORMING AN ALLOCATION
OF MEMORY AND A COPY ON LARGE IMAGES.
