Hi Prasanta,
Thankyou for the review.
The code compiles , Actual scenario is as below:
public class Temp {
AccelSurface as = new AccelSurface() {};
SurfaceData sd = (SurfaceData)as;
}
class SurfaceData {}
interface Surface {}
interface AccelSurface extends Surface{}
class D3DSurfaceData extends SurfaceData implements AccelSurface{}
class OGLSurfaceData extends SurfaceData implements AccelSurface{}
-------------------
In suggested fix, the SurfaceData is always of type D3DSurfaceData.
And hence getDefaultScaleX/Y holds good. OpenGL rendering is handled
in a different flow.

<http://cr.openjdk.java.net/%7Epkbalakr/8144735/webrev.02/>
Suggested fix also resolves the following failures on hidpi windows 8
javax/swing/JWindow/ShapedAndTranslucentWindows/PerPixelTranslucent.java
javax/swing/JWindow/ShapedAndTranslucentWindows/PerPixelTranslucentGradient.java
javax/swing/JWindow/ShapedAndTranslucentWindows/SetShapeAndClickSwing.java
javax/swing/JWindow/ShapedAndTranslucentWindows/ShapedPerPixelTranslucentGradient.java
javax/swing/JWindow/ShapedAndTranslucentWindows/ShapedTranslucentPerPixelTranslucentGradient.java
javax/swing/JWindow/ShapedAndTranslucentWindows/TranslucentPerPixelTranslucentGradient.java
----------------------
OpenGL Rendering issue will be addressed in JDK-8164811
<https://bugs.openjdk.java.net/browse/JDK-8164811>

I wonder how it compiles?
I tried a small program
------------------
public class Test {
AccelSurface b = new AccelSurface();
SurfaceData c = (SurfaceData)b;
}
class SurfaceData extends Surface {}
class Surface {}
class AccelSurface extends Surface {}
---------
and it fails to compile
Test.java:3: error: incompatible types: AccelSurface cannot be
converted to SurfaceData
SurfaceData c = (SurfaceData)b;
ANyways, did you check with opengl pipeline? It seems
getDefaultScaleX/Y is not present in OGLSurfaceData which will result
in falling back to SurfaceData in which case the scale will be 1.

Prasanta

Hi Alexandr,
AccelSurface is implemented by *ONLY* D3DSurfaceData and
OGLSurfaceData classes,
Both of these classes extend SurfaceData as well.
Hence, casting of 'as' variable which is of type AccelSurface
object to SurfaceData is always VALID.

Prem

YES scaled SurfaceData returns proper scale values from
getDefaultScaleX()/getDefaultScaleY(), which I have used in
the current patch.
Please review the updated patch

Is it always true that the 'as' variable which has type
AccelSurface in the fix is always instance of SurfaceData?
Thanks,
Alexandr.

Hi Alexandr and Sergey,
Please review the updated patch.

>>“It is a little bit strange bug, because VolatileImage
should handle this scale internally, and create double sized
surface when necessary”.-Sergey
Yes as you mentioned Volatile Image is getting scaled
internally. Thanks for the feedback.
*Cause:*In VIOptWindowPainter::updateWindowAccel(psdops, w, h)
call, width and height were passed without scaling,
which was creating a bitmap of specified width and height,
hence the output was clipped.
I just have two general questions.
- The scaled SurfaceData should return proper scales from
getDefaultScaleX()/getDefaultScaleY() methods. Do these
methods return right values after setting the scaled image
sizes in the fix?
- Region.clipScale() which is used in many places rounds
values. The usual rule is to use Math.floor() for image
coordinates rounding and Math.ceil() for sizes.
Should the same rule be applicable here?
Thanks,
Alexandr.

Prem

*Issue:*
javax/swing/JWindow/ShapedAndTranslucentWindows/TranslucentPerPixelTranslucentGradient.java
fails
*Cause:*
While creating Transparent VolatileImage, width and height was
NOT hidpi scaled.
*Fix: *VolatileImage width and height are scaled.
I believe this is an issue in AWT and needs to be discussed
on awt-dev alias.
Should the backbuffer width and height be also scaled for
the BIWindowPainter?
Thanks,
Alexandr.
