With VC2010 java.c ::ShowSplashScreen fails with segmentation fault on
calling free on scaled_splash_name .
This failure is due to different C runtime used by libjli and lib splashScreen.
Fix: Allocating a max scaled image name length buffer in java.c and
passing it to splashscreen_sys.c
Just few small comments:
- SplashGetScaledImageName can return a boolean value which indicates that
high-resolution splash screen has been found
- The getMaxScaledImageNamePostfixLen function can be added which just
returns max length of the scaled image postfix.
It allows to control this value on the java.desktop side rather to keep
it in java.c file
- systemScale.cpp copyright need to be updated to 2016
Thanks,
Alexandr.

Hello All,
Please review the updated webrev.
http://cr.openjdk.java.net/~rchamyal/8145173/webrev.04/
Alexandr : I have build code with VS2013 and I didn't get any errors you
mentioned.
Still I have updated the code as suggested.
Added build team for make file review. JPRT build with fix was successful.

You need to move variables declaration to the beginning of a statement.

Added a free call for duplicate file name in
splashscreen_sys.c :: SplashGetScaledImageName
http://cr.openjdk.java.net/~rchamyal/8145173/webrev.02/
<http://cr.openjdk.java.net/%7Erchamyal/8145173/webrev.02/>
awt_Win32GraphicsDevice.cpp
656 dpiX = GetScreenDpi(GetMonitor());
657 if (dpiX > 0) {
658 dpiX = dpiX >= 96 ? dpiX / 96 : dpiX;
659 SetScale(dpiX, dpiX);
The Windows HiDPI graphics support was designed to handle both DPI
X and Y scales. The GetScreenDpi should return both values to be
used in SetScale method.
systemScale.cpp
38 float scale = -2.0f;
39 if (scale == -2) {
Initially the scale variable was defined as static to avoid rereading the
J2D_UISCALE test variable each time.
It is better to preserve the "// for debug purposes" comment also.
MultiResolutionSplashTest.java
+ scaleFactor = (float)((SunGraphics2D)
g).surfaceData.getDefaultScaleX();
Now it is possible to get the the scale factor using
GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDev
i
ce().getDefaultConfiguration().getDefaultTransform().getScaleX()

Alexandr.

Hello All,
Could you please review the following fix.
Bug : https://bugs.openjdk.java.net/browse/JDK-8145173
Webrev :
http://cr.openjdk.java.net/~rchamyal/8145173/webrev.00/
<http://cr.openjdk.java.net/%7Erchamyal/8145173/webrev.00/>
This is an enhancement to support HiDPI splash screen on windows.
As a part of this enhancement implementation to
splashscreen_sys.c::SplashGetScaledImageName method has been
provided.
System dpi and scale factor are used to determine the scaled
image name. Dpi value is read using GetDpiForMonitor API on
Windows 8 and GetDesktopDpi API on Windows 7.
Scale factor is calculated from the dpi value.
The naming convention followed for scaled image name is as
follows:
Refer :
https://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh965325.a
s
px
Unscaled image name : image.ext
Scaled image name : image.scale-<dpi value>./ext/
