If the value corresponding to delayN is 0 in the apng information, I wonder why it is animated normally in the browser

delayN information was referring to js lib (https://github.com/davidmz/apng-js/blob/master/src/library/parser.js#L62)).

The apng-js lib corrects frame.delay to 100, but does the browser do the same? (https://github.com/davidmz/apng-js/blob/master/src/library/parser.js#L71) If delayN(delay_num) is 0, shouldn't it not work in browser(chrome)?

I want to know how to handle it in the browser(chrome)

Ref.

if the duration of apng is 0, then a crash occurred on the android app. So I was curious about the reason why it is animated normally in the browser.

  • The specs you linked to says "If the the value of the numerator is 0 the decoder should render the next frame as quickly as possible, though viewers may impose a reasonable lower bound." Why would you expect it to not animate? Or are you wondering only about what's the delay in the current Chromium implementation? – Kaiido Dec 13 '22 at 11:07
