Hello,
Could you review the fix:
bug: https://bugs.openjdk.java.net/browse/JDK-8160124
webrev: http://cr.openjdk.java.net/~alexsch/8160124/webrev.00
Let's set the clip [x=5, y=5, width=5, height=5] to a graphics and
call the hitClip() with the passed rectangle [x=0, y=0, width=5, height=5].
The result is false for the graphics with scale 1 and true if the
scale is floating point 1.5.
This is because the transformed clip which has floating point bounds
[7.5, 7.5, 7.5, 7.5] for the scale 1.5 has bounds with rounded down
upper-left and rounded up lower-right corners [7, 7, 8, 8] which now
intersects with the transformed rectangle [0, 0, 7.5, 7.5].
The proposed fix adds additional check for the user clip and the user
rectangle intersection if the intersection with the region clip passes.
Thanks,
Alexandr.
