Hi, The ASF Community folks were asking for SVG or high-res versions of product logos, and I realized Taverna didn't really have one, as we only have a 256x256 PNG:
https://taverna.incubator.apache.org/img/taverna-logo-256x256.png For years I have been looking for the original vector version of our logo, but this is the best I've found so far. Anyone else have something in their email archives..? A bitmap format like PNG is bad because it can't scale well with web pages, particularly relevant for mobile/tablet phones or if scaled up on a poster printout. A vector format like SVG should be preferable and is now supported in all major browsers. Now I had a quick trace of the png in Inkscape and managed to come up with: http://taverna.staging.apache.org/img/apache-taverna-logo.svg Comments? Vectorizing by tracing the bitmap is a bit of cheating, so you will notice this file is actually larger in file size (216 kB) than the PNG (72 kB). This is basically the coastline measuring paradox. If I click "Simplify" in Inkscape I can reduce the details to a managable 32 kB, but then the cogs turn into wobbly circles! Here you can see what the svg might look like used in larger size: http://taverna.staging.apache.org/ Try zooming in on a high-res tablet or screen to check the details. For comparison if we use the old PNG: http://taverna.staging.apache.org/tmp/logo-png.html or even a PNG (56 kB) exported from the new SVG http://taverna.staging.apache.org/tmp/logo-png2.html .. then we see a clear difference in the SVG. For the logo in the top corner there is practically no visual difference as it's so tiny. Comparing the SVG with the original PNG will show information lost in the trace, e.g. the inner edges of the cog. An alternative might be to try to recreate some cogs in Inkscape or Adobe Illustrator, this should bring back the details and probably shrink the SVG size. But that would take more time... any volunteers? I've updated the banner which should then be better for print: http://taverna.staging.apache.org/img/apache-taverna-banner.svg I've not played with removing the gradient to a single-color, that can reduce file size, but makes it harder to pick the right orange.. What do you think? Just keep the SVG as a side-resource for anyone interested? -- Stian Soiland-Reyes The University of Manchester https://www.esciencelab.org.uk/ https://orcid.org/0000-0001-9842-9718
