  158. Zash I haven't read it as png only. Rather that one of the possibility multiple formats must be png, but you can publish alternative formats

  164. MattJ The first point in section 3 says: "1. User publishes avatar data for "image/png" content-type to data node and optionally publishes other content-types to HTTP URLs."
  165. MattJ That sounds very much like only PNG data is welcome in the PEP node, and the rest of the doc seems to back up such an interpretation

  173. Zash Pointless limits, let's remove them. Mandating that at least one format be widely supported is good, but today jpeg and gif should be fine along with png.

  189. flow serious question: why would you want to have your avatar in multiple formats? shouldn't png just always be fine?
  190. Zash Jpeg deals better with photos
  191. edhelas webp
  192. Zash But you could also have a higher resolution available as alternative version
  193. Zash webp doesn't work everywhere
  194. Zash You could have it as alternative format if you wanted
  195. winfried has left
  196. winfried has joined
  197. Zash Or you could have png+svg.

  205. larma make svg required and then don't base64 encode the svg, but just embed it. If you still wanted to use other image formats, you can embed them in svg

  216. lovetox larma, why though seems complicated
  217. lovetox i read a file from my harddisk in bytes, pass it to the b64encode and im finished, i dont have to care if that svg is valid xml at all
  218. mukt2 has left
  219. lovetox i dont want to care if something is a svg, then i have to read, decode it, add the xml to as child etc, and if its another format i have to base64 encode it .. make everything just more complex
  220. lovetox for a bit less size on a payload which is rarley requested at all
  221. lovetox also png is fine as almost all supports it
  222. lovetox its the other way around, publish png, and if you want something more add other formats
  223. lovetox flow, on desktop we often deal with hidpi displays
  224. lovetox we need to scale the avatar x2 or even x3
  225. sonny has left
  226. sonny has joined
  227. lovetox svg solves that nicely
  228. mukt2 has joined
  229. Zash So why not have the ability tp publish a higher resolution along with the mandated 96x96 png or whatever
  230. lovetox you have this ability already Zash
  231. lovetox its just that other formats are not allowed than png
  232. lovetox for me the optimal case is
  233. Zash Wasn't it just argued that you could only have one item?
  234. lovetox user selects a svg, i publish a png in 100x100 or something, and add the svg in a second avatar info, so clients that support svg can use that
  235. lovetox where Zash?
  236. lovetox The XEP says the <data> node is only for PNG
  237. Zash That. That's silly.
  238. lovetox i know
  239. lovetox and mostly ignored anyway
  240. Zash The part MattJ quoted
  241. Zash So let's update it to be sane?
  242. lovetox i remeber a time when C only published in webp
  243. lovetox yes the part that MattJ quoted, says other "content-types"
  244. MattJ The way we usually handle this is "You must publish X, you may optionally publish other things"
  245. lovetox you can post image/png in 100 resolutions if you want to pep
  246. lovetox but not another content type
  247. Zash What's the point of a info/@type attribute if the only option is png?
  248. MattJ I'd be happy with even a SHOULD support PNG, it's tricky hard-coding something here that may evolve over time (when the rest of the documented protocol would hold up fine)
  249. Zash MattJ, yes, that
  250. Zash Like with hash algos
  251. lovetox but it already has a MUST
  252. lovetox > and one of the formats MUST be "image/png" to ensure interoperability
  253. lovetox can we not just remove the word "only"
  254. lovetox its not normativ language
  255. lovetox so i guess the creator didnt think this is important anyway
  256. eevvoor has left
  257. sonny has left
  258. lovetox we just remove that part "and only for the "image/png" content-type"

  319. Link Mauve “12:35:32 flow> serious question: why would you want to have your avatar in multiple formats? shouldn't png just always be fine?”, SVG is much smaller for vector data, and can work at arbitrarily high resolutions.
