             Summary: Support SVG icon loading from ImageUtilities
                 Key: NETBEANS-2604
                 URL: https://issues.apache.org/jira/browse/NETBEANS-2604
             Project: NetBeans
          Issue Type: Improvement
          Components: platform - Other
    Affects Versions: 11.0
         Environment: Windows, MacOS, and Linux.
            Reporter: Eirik Bakke


Support SVG image loading from ImageUtilities, primarily for icons. This would 
be implemented as a special subclass of javax.swing.Icon, rather than through 
MultiResolutionImage. Eirik Bakke already has most of this code ready.

Motivation: 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). Two 
approaches are possible: (1) allow each icon to be supplied as multiple bitmap 
(i.e. PNG) files, one for each resolution, or (2) allow each icon to be 
supplied as a single SVG file. This issue deals with the latter approach. (The 
multiple resolution approach is discussed in NETBEANS-1583 .)

On Windows, arbitrary HiDPI scaling factors may be specified, such as 150%, 
175%, 200%, or 250%. Additionally, MultiResolutionImage does not work properly 
on Windows due to https://bugs.openjdk.java.net/browse/JDK-8212226 . Thus, I 
now consider the SVG approach to be the most feasible one.
