In the thumbnailing system jpegs get sharpness applied to them since commons typically has photographs as jpegs and those get better quality with sharpness applied to them. However, some files exist where they should be sharpened but are not. Drawings would not benefit from sharpening, so the idea is to use an property to specify the files that would gain from using sharpness. This allows the community to select where sharpness should be used for thumbnails. See also phab:T253280 and phab:T256959 for the whole context.

Chose an item type of a property since it makes it multilingual and to limit the options of values that can be entered.--Snævar (talk) 13:10, 6 December 2022 (UTC)[reply]

Used for specifying to the thumbnailing backend whether sharpness should be used or not, as per phab:T47212, which is being worked on. The dev working on it expects the community to create test data, hence this proposal. Would only be used on commons in structured data. There is only a small dev team (2-3 people) working on the thumnailing system.--Snævar (talk) 23:28, 15 December 2022 (UTC)[reply]
