[jira] [Created] (NETBEANS-3469) Cache PNG versions of loaded SVG
icons
Eirik Bakke created NETBEANS-3469:
-------------------------------------
Summary: Cache PNG versions of loaded SVG icons
Key: NETBEANS-3469
URL: https://issues.apache.org/jira/browse/NETBEANS-3469
Project: NetBeans
Issue Type: Improvement
Components: platform - Other
Affects Versions: 11.3
Reporter: Eirik Bakke
Support for SVG file loading via ImageUtilities was added in NETBEANS-2604. Once a substantial number of icons have been migrated to SVG versions ( NETBEANS-2617 ), we should consider doing some performance work to ensure that icons can be loaded as quickly as before in the common case. See the benchmark and discussion in https://github.com/apache/netbeans/pull/1278 .
timboudreau had the idea of caching rasterized versions of the SVG icons in the cache directory the first time they are loaded (and painted at a specific HiDPI scaling factor). I'd guess that this could speed up SVG file loading by about 4x. If all icons are cached, it would also save the overhead of loading the ~3MB Batik library JARs.
