Converting Formatted Text to SVG

[alderg]

SVG Label Rendering Option

By default, formatted text and text with word wrapping are rendered as HTML using foreignObject elements. However, this approach may cause compatibility issues in certain viewers.

Enabling this option will attempt to render labels as SVG, using <text> and <tspan> elements instead of HTML. Currently, the following is supported: bold, italic, underline, strikethrough, ^superscript, _subscript, <font> and <span> elements. If the label cannot be represented as SVG, a foreignObject will be used instead.

Note: Word wrapping is disabled for labels that were successfully converted when this option is enabled.

Requires v28.0.3 or later

Hey,

Thanks a lot for that feature!

Are you planning on implementing a way to explicitly emit an error/warning during drawing or/and exporting to svg, rather than silently falling back to foreignObject ?

This feature is indeed useful - I wonder, could it be extended to include the background color also?

I realise that technically SVG canvas color does not exist, but this can be overcome by using <rect width="100%" height="100%" ...> and placing everything else on top of that.

Indeed that appears to be what happens when you export diagrams via [File > Export as > SVG] and deselect transparent background.

Certainly this would help for many of my own diagrams, which rely on the label background color to contrast against underlying objects.

Need this feature. Text in text boxes get truncated when the SVG imported into LibreOffice Writer. I noticed the problem still persists in v29.2.7.

Use Convert labels to SVG instead:

See #5165

This doesn't work. <tspan> tags are generated but the text is truncated. In fact, I stumbled on this thread via that link in the UI.

Can you share a test case?
