Image use instructions[edit]

The section "Animated GIF" now says that "inline animations should be used sparingly". This seems odd. The rest of the page is about uploading, not use. Is this about use in galleries, policy pages or what? I suppose it is a guideline of some Wikipedia, which for some reason has been repeated (or written) here. In that case I suppose the paragraph should be removed. If the reason is some other, one should explain what use this is about. --LPfi (talk) 15:38, 6 June 2019 (UTC)

@LPfi: I use 3 animated gif files on my user page: File:Qxz-ad2.gif; File:Movicons2-hello.gif; and File:Welcomebanner.gif. The latter 2 have been there for 9 years. Is that wrong?   — Jeff G. please ping or talk to me 16:01, 6 June 2019 (UTC)
I think they (at least the one I spotted) make reading the adjacent text significantly harder, so I think the "niceness" value should be given less weight than the accessibility issue. I would however give significant leeway for designing user pages. If this is a significant problem, the guideline about user pages should note it. The issues are different on different pages, and users adding content to pages are probably not coming here for advice, so if we want to keep the paragraph, there should be links to here and the paragraph should include a discussion presenting the issues. --LPfi (talk) 09:09, 7 June 2019 (UTC)
@LPfi: I added alt text to my uses in these edits.   — Jeff G. please ping or talk to me 17:18, 7 June 2019 (UTC)
The issue is that something that moves or changes shape distracts from the reading. I have to make an effort to concentrate on the text, which I wouldn't need otherwise. With my former web browser it was easy to turn off such animations (still two or three clicks before reading instead of just reading), but on this I do not know an easy way to do it. With fvwm it is easy to move some other element (the clock, an xterm, ...) over the disturbing image, but e.g. windows insists the active window being on top. I suppose some users will have real difficulties reading the text, but as this is not Wikipedia, they can just skip reading with not much harm done. --LPfi (talk) 15:38, 9 June 2019 (UTC)

Guidance on pdf vs svg[edit]

Inkscape has become significantly better at converting PDFs, and rsvg significantly better at rendering them. But this page, which should provide guidance, just notes that yes, SVG is good and PDF is also good for vector files. Is there any kind of consensus on how strongly to prefer SVG over the original file? Or always upload original PDF even if it's less accessible? SilverbackNettalk 18:25, 17 October 2019 (UTC)

PDF's strength is stuff laid out on a certain-sized page in multi-page documents. If you have a single vector graphic which is not tied to the layout of a particular page, then SVG would generally be preferable. AnonMoos (talk) 10:46, 9 December 2020 (UTC)
To add on AnonMoos, the thumbnails of the PDFs uploaded here are in JPEG, so even if the image is vector, when rendered as a JPEG thumbnail, it could look bad. This is not the case with SVG, whose thumbnails are rendered as lossless PNGs instead. SVG is designed for web publishing anyway, unlike PDF, so you should always use SVG when publishing graphics to the web. pandakekok9 13:56, 9 December 2020 (UTC)

Permit uploading fonts[edit]


have you ever thought about permitting users to upload fonts to commons? This would permit people such as myself who ardently write wikibooks to gain greater control over the typesetting of their scribbles. --Mathmensch (talk) 13:06, 22 February 2020 (UTC)

Hi Mathmensch, I am not sure if the existing Webfonts would fit your needs? They can be used on Wikibooks too. For a complete list of existing Webfonts with examples see de:Hilfe:Schriftunterstützung/Webfonts. If you need other fonts the fonts could by uploaded to the WMF server via a software patch. The font must be licensed under a free license. Raymond 15:49, 22 February 2020 (UTC)
Hello Raymond, thank you very much indeed. This is exactly what I was looking for. --Mathmensch (talk) 09:36, 23 February 2020 (UTC)

Use of 16-bit tif format to preserve depth of colors[edit]
