Scenario

• JaCoCo version: 0.8.11.202310140853
• Operating system: macOS 14.4.1
• Tool integration: Gradle 8.4
• Description of your use case: Create HTML report after tests complete

Current Behaviour

The tool emits coverage with GIF images as background image.

Wanted Behaviour

Use image assets in SVG format - or PNG output based on SVG. Here are some initial SVG mocks I have from playing around with Freeform.

Possible Workarounds

Ask some GenAI solution to autogenerate SVG equivalents of the existing image assets.

The icons are Eclipse/Eclemma icons which are already SVG:

Thanks for clarifying

[marchof]

I still think this is a valid enhancement request to actually use SVGs in JaCoCo html report.

[huangsam]

Thanks for reopening. Yeah it would be great to have sharp images on the HTML report especially given that screen resolution has gotten considerably better with laptop and monitor displays - and user's expectations for UX are higher in recent years. Modern browser support for SVG is pretty good now
