Preview rendering of barcode diagrams is not working

[SjoerdV]

Please provide details about:

• What you're trying to do Preview rendering of barcode diagrams
• What happened Preview is not rendering barcodes
• What you expected to happen Preview should render barcodes, while pdf/html export does show barcodes in exported file through ruby gem

example: https://docs.asciidoctor.org/diagram-extension/latest/diagram_types/barcode/

Barcodes can be written codabar:A31117013206375A[png, height=10] inline or as blocks.

Hello World!

We'll also need your system information (get it under "Help" -> "About" in VS Code). Share the installed extension version Product: VS Codium Version: 1.82.2 Release: 23257 OS: Linux x64 AsciiDoc: v3.1.5

Asciidoctor Diagram is not available in a JavaScript environment and Asciidoctor Kroki does not support barcode. In other words, this is an upstream "issue" (more specifically a feature request) and not something we can fix in the VS Code Extension.
