<AWT Dev> RFR: 8196087: java/awt/image/DrawImage/IncorrectUnmanagedImageRotatedClip.java fails

Thu Oct 29 04:19:49 UTC 2020

The test draws some specific pattern to the VolatileImage and to the BufferedImage, and then compare pixels.

The test uses the getSnapshot() method to get the pixels from VolatileImage, and this method produces some interpolation "artifacts" if the fractional scale is used in the system(like 125%).

The solution is to use some predefined scale factors.
