No high resolution icon (png)

[javierllorente]

Apache NetBeans version

Apache NetBeans 16 release candidate

What happened

netbeans.icns is 512 x 512 pixels whereas netbeans.png is 32 x 32 pixels. This low resolution makes it look blurry on KDE.

How to reproduce

Unzip the binary zip and head to netbeans/nb/. There you will see that netbeans.png is low-res.

Did this work correctly in an earlier version?

No / Don't know

Operating System

openSUSE Tumbleweed / KDE Plasma

JDK

OpenJDK 17.0.4

Apache NetBeans packaging

Apache NetBeans binary zip

We have high resolution frame icons, which are picked up fine by Gnome. Any idea what KDE is doing differently and where it's picking the low resolution icon from?

[javierllorente]

Where are those high resolution icons in the binary zip? I thought netbeans.png was picked for the taskbar, hence my pull request.
Even if KDE is picking the low resolution icon, don't we need a high resolution one for creating a .desktop file (affects any DE)?

[neilcsmith-net]

They're inside core.startup so of less use for a desktop file - https://github.com/apache/netbeans/tree/master/platform/core.startup/src/org/netbeans/core/startup

I think an SVG might be a better option in a desktop file? Although possibly with a PNG backup. Depends if you're installing them or providing a file path. I think they need to be added alongside the existing icon in NetBeans distribution though.

There's a fixed up SVG and a 48x48 PNG in NBPackage used for creating DEB, etc. - https://github.com/apache/netbeans-tools/tree/master/nbpackage/src/main/resources/org/apache/netbeans/nbpackage The SVG needed proportions fixing and comments removing to work properly on Gnome. I have a feeling that the XDG spec says a 48x48 icon is the minimum that must be provided if installing as icons, hence the DEB provides that plus SVG.

[javierllorente]

I also think that a SVG would be a better option. Perhaps we could include https://github.com/apache/netbeans/blob/master/nbbuild/javadoctools/siteresource/apache-netbeans.svg in the binary zip?

The Icon Theme Specification recommends a 48x48 icon;
"So, you're an application author, and want to install application icons so that they work in the KDE and Gnome menus. Minimally you should install a 48x48 icon in the hicolor theme."

The "old" Linux installer created a desktop file with a lo-res icon.

The Snap distribution has the 512x512 png, that looks fine.

@javierllorente I had difficulties with Gnome not loading that SVG, tracked to issues with the license header, which is why the NBPackage SVG is different from that one. Would need to validate what works across OS.

@lkishalmi see things like #4776 - it would be useful to have higher quality icons bundled in the zip.
