We've several options when doing SVGs. For diagrams, we can use actual text elements, but this may suffer from problems arising with variation in fonts. Luckily, most platforms are expected to ship with Times and Arial, or metric-compatible clones (e.g. Liberation Serif/Sans). If we tolerate "graceful degradation" as we already did by publishing the HTML version, then we can probably settle with this.
On the other hand, there's the option of "embedding" the fonts into the SVG files, however that'll make the file bigger, especially with glyphs that may not be used (such as Q or Z). Alternatively, if program supports, the Bezier paths of individual used glyphs may be referenced and reused to "construct" text-looking elements. For maths formulas however, it's probably best to resort to Bezier paths of symbol glyphs. Because each individual special symbols may probably be only used once, and the visual of the formula isn't as complex as diagrams in terms of layout. > 2025年6月24日 21:15，Geoff Clare via austin-group-l at The Open Group > <austin-group-l@opengroup.org> 写道： > > Niu Danny wrote, on 24 Jun 2025: >> >>> >>> I tried a conversion to PNG and the file reduced from 43K to 31K. >>> Such a small difference hardly seems worth the bother. >>> >> >> Appreciated.
