Lokhu kwenza kube ngcono ekunikezelweni futhi kungaphawuleka nganoma yini enye - amathuluzi okuhlela, ama-gallery wefoni namadivayisi adala ahlala ekhohlwa. Ukushintshana kufomethi yokusetshenziswa okujwayelekile kwenza ukuthi okuqukethwe okuthunyelwe kusebenziseke ngaphandle kwe-web. I-WebP ivame ukuba 25-35% ncane kune-JPG elinganayo futhi ncane kune-GIF ephilayo, ngosizo lwesiphequluli esiphelele kusukela ngo-2020.

Yini isilungiselelo sekhwalithi okufanele ngiyisebenzise uma ngiguqula ku WebP?

Ukushintsha kufomethi ngaphandle kwe-alpha kuyilapho kudlula khona okungalungile: izifunda ezibonakalayo zigcwele umbala oqinile, ngokuvamile omnyama noma omnyama, futhi akukho indlela yokubuyela emuva encane yokufihla isiqephu futhi.

Ingabe ifreyimu yokuhlela isikhathi kanye nokujikeleza ihlala iguqula i WebP?

Kufomethi enye ekwaziyo ukubukeka, yebo — amaphutha ngefremu ngayinye kanye nokubalwa kwe-loop kugcinwa kwifayela futhi kuthunyelwe. Kufomethi ehlala khona ifremu eyodwa kuphela ephila, ngokuvamile i-first. Kuvidiyo i-loop flag ayikwazi ukubuyela lapho, ngoba umdlali ukhetha ukuthi uphinde. Khangela isivinini sokudlala ngemuva lapho i-frame rate ishintsha: i-rate eqinile ingafinyelela kuphela amaphutha aguqukayo nge-frame.
