Prem,
I believe it's possible to use AccelSurface.getBounds() method and skip
casting to SurfaceData completely.
The calculations are basically the same.
According to the comments in the TranslucentWindowPainter.createInstance
you will get BIWindowPainter even for OpenGL pipeline unless you force
optimized path via sun.java2d.twp.forceopt so you will need to check
these paths in the fix for OpenGL.
Thanks,
Vadim

Ok. so long you are addressing the opengl issue albeit via different
bugid, it's ok with me. +1.

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.

Suggested fix also resolves the following failures on hidpi windows 8

javax/swing/JWindow/ShapedAndTranslucentWindows/SetShapeAndClickSwing.java

OpenGL Rendering issue will be addressed in 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.

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.

>>“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

While creating Transparent VolatileImage, width and height

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?
