Eirik Bakke updated NETBEANS-1583:
----------------------------------
Description:
To look good on HiDPI/Retina displays, the NetBeans IDE, and NetBeans Platform
(RCP), applications will eventually need to provide high-resolution versions of
various image asset (typically icons). In Swing, multi-resolution image assets
are supported via the
[MultiResolutionImage|https://docs.oracle.com/javase/10/docs/api/java/awt/image/MultiResolutionImage.html]
class; such images are automatically loaded by methods such as
Toolkit.getImage based on a standard naming convention. For instance, on MacOS,
Toolkit.getImage("myicon.png") will also load the file "myi...@2x.png" if
present, returning a MultiResolutionImage (see
[https://bugs.openjdk.java.net/browse/JDK-8011059] ). NetBeans'
ImageUtilities.loadImage and friends should do the same.
The same naming convention for multi-resolution image assets should be used as
in the JDK. See Philip Race's comment on
[https://bugs.openjdk.java.net/browse/JDK-8151787] :
{quote}The proposed name convention for splash screens *and* other multi-res
images is @125pct @150pct @200pct @2x @250pct @300pct @3x
ie @2x and @3x are supported as synonyms for @200pct and @300pct respectively
and also because we already supported @2x on retina Mac.
{quote}
(On the naming convention, see also
https://bugs.openjdk.java.net/browse/JDK-8090575 )
As far as I know, only MacOS currently supports the automatic loading of such
assets via Toolkit.getImage, but both Windows and MacOS (and Linux?) support
the underlying MultiResolutionImage. So it's already possible to implement this
on the latest JDK. Note, however, that we should probably wait for
https://bugs.openjdk.java.net/browse/JDK-8212226 to be fixed before enabling
this on Windows.
