Hi, Alex. Beware that MultiResolutionImage is not reliable on Windows due to https://bugs.openjdk.java.net/browse/JDK-8212226 . It would seem very easy to fix the latter bug, though. Just have SunGraphics2D.drawHiDPIImage return false instead of null if img is a MultiResolutionImage with zero dimensions.
(I discovered the bug above while implementing HiDPI/SVG icon support for the Apache NetBeans IDE. We ended up having to avoid MultiResolutionImage altogether on Windows.) -- Eirik From: awt-dev <awt-dev-boun...@openjdk.java.net> On Behalf Of Alexander Zuev Sent: Monday, March 30, 2020 7:19 AM To: awt-dev@openjdk.java.net Subject: <AWT Dev> RFR: 8182043 Access to Windows Large Icons Hello, please review my fix for the issue 8182043: Access to Windows Large Icons Bug: https://bugs.openjdk.java.net/browse/JDK-8182043 Webrev: http://cr.openjdk.java.net/~kizune/8182043/webrev<http://cr.openjdk.java.net/~kizune/8182043/webrev/> Main idea is to provide a new API call to retrieve image of the specified size and to make Windows implementation that for all the resolutions higher than 24 pixels returns the multi resolution image icon with image inside being the highest quality icon available and the size set to the size requested by the user. This way we will have good scaling across the different resolution while maintaining relative sizes in the UI intact. The exception made for images size of 24 and less since sometimes application has different image for the small icons in its resource section which is optimized to make sure that on low resolution screen this icon is not displayed as just scaled down blurry little square. /Alex
