Hello Semyon,
Your suggestion regarding _NET_WM_ICON requires some investigation

multiresolution image: wrong resolution variant is used as icon in

Hello Semyon,
The resolution variant image returned is based on the
implementation of
BaseMultiResolutionImage::getResolutionVariant API.
Current implementation of
BaseMultiResolutionImage::getResolutionVariant returns a
resolution variant image which has width and height greater
than or equal to the passed width and height.
There is a known issue on it:
JDK-8148619 Select the closest resolution variant in
BaseMultiResolutionImage
https://bugs.openjdk.java.net/browse/JDK-8148619
Thanks,
Alexandr.
In the case you have suggested dimensions of RED and BLUE
images are 32 and 80 respectively.
Width and height passed to getResolutionVariant is 64 i.e.
scaled width and height of base image(RED) (GDK_SCALE=2) and
blue image is getting returned.
The width and height passed to this API is that of base image
not of the spot.
Applications can control this behaviour by overriding this API
in derived classes.

[hidpi] multiresolution image: wrong resolution variant is
used as icon in the Unity panel

Hello Rajeev,
The taskbar icon is ok now.
I change the resolution variants from the test a bit:
final BaseMultiResolutionImage IMG = new
BaseMultiResolutionImage(
new
BufferedImage[]{generateImage(4, Color.RED),
generateImage(10, Color.BLUE)});
And the icon I see in the taskbar and in the button is
blue. It seems to me the first resolution variant (red) is
more appropriate in this case because its size is closer
to the spot. I'm not sure if this is an issue.
I have an extra question to you and Alexander.
Most native apps on Linux set an array of icons with
_NET_WM_ICON. Usually they are [16x16, 32x32, 64x64].
So, desktop environment may select icon of appropriate size.
In this fix we are preselecting icon of a specific size in
the app and send it to WM.
Why not to send array of the resolution variants images
and let the desktop environment to select the appropriate
one, like native apps do?
This sounds as good idea. MultiResolutionImage has the
special method for this "List<Image> getResolutionVariants()".
We do the similar on Mac OS X where NSImage with several
representations is created from a MultiResolutionImage:
http://cr.openjdk.java.net/~alexsch/8028212/webrev.01/src/macosx/classes/sun/lwawt/macosx/CImage.java.udiff.html
<http://cr.openjdk.java.net/%7Ealexsch/8028212/webrev.01/src/macosx/classes/sun/lwawt/macosx/CImage.java.udiff.html>
It has sense to try the same approach on Linux.
Thanks,
Alexandr.

JDK-8147648 [hidpi] multiresolution image: wrong
resolution variant is used as icon in the Unity panel
Hi Rajeev,
I have added 1px border to the icon in your test:
private static BufferedImage generateImage(int
scale, Color c) {
int x = SZ * scale;
BufferedImage img = new BufferedImage(x, x,
BufferedImage.TYPE_INT_RGB);
Graphics g = img.getGraphics();
if (g != null) {
g.setColor(c);
g.fillRect(0, 0, x, x);
g.setColor(Color.YELLOW);
g.drawRect(0, 0, x-1, x-1);
}
return img;
}
It seems the icon in the taskbar is not correct for UI
scale > 1.
By the way, graphics object should be disposed using
g.dispose() when it is not needed anymore.

Bug:
https://bugs.openjdk.java.net/browse/JDK-8147648
Issue: Wrong resolution variant is used as
icon in the Unity panel.
Cause: The screen transforms are not
applied to find the correct resolution
variant image in current implementation.
Fix: Applied the screen transforms to
graphics object.
222 int scaleX = (int)tx.getScaleX();
223 int scaleY = (int)tx.getScaleY();
224 DataBufferInt buffer = new
DataBufferInt(scaleX * width * scaleY * height);
The fix is in the shared code and the scale
factor can have floating point value on
Windows. (for example 1.5).
It is better to round the final width and
height after scaling them.
Thanks,
Alexandr.
