Ewe, kwaye loo nto yinto enye ekufuneka uyazi malunga nefomati. Ukugcina ngalunye luphinda luqhube i-lossy encoder ngaphezulu komfanekiso osele ugqithisele kuyo, ngoko ke i-artefacts idityaniswa - ibonakala njenge-blocking ejikeleze umbhalo kunye ne-haloes kumazantsi anzima emva kweentsuku ezininzi zobuhlanga. Hlela ukusuka kwi master engalahlekiyo kwaye urhwebe ngaphandle kwi WebP kabini, kwisiphelo, kunokuba uvule kwakhona ugcine kwakhona ifayile efanayo. I-WebP inikezela zombini iimeko ezilahlekileyo nezingalahlekileyo, ngokubonisa ngokucacileyo kwe-alpha noopopayi abafumanekayo kumnye.

Kutheni i-web inikezelwa njenge WebP?

Kuba yakhiwa ngokuchanekileyo kulo msebenzi: iifayile ezincinci, iqala ngokukhawuleza, akukho plugin kwaye akukho layisenisi yokukhathazeka ngayo. Oku kwenza ukuba igqibelele ekunikezeleni kwaye ingaphawulwanga nantoni na enye - iisixhobo zokuhlela, ii galleries zefowuni kunye neesixhobo ezidala zihlala ziyihoyi. Ukuguqula kwifomati yomsebenzi oqhelekileyo yenza ukuba imixholo elayishwe ezantsi isebenziseke ngaphandle kwe web. I-WebP ihlala i-25-35% incinane kune-JPG elinganayo kwaye incinci kune-GIF ephilayo, enesixhaso se-browser esipheleleyo ukusukela ngo-2020.

Yintoni isicwangciso somgangatho endingayisebenzisa xa ndiguqula kwi WebP?

Indawo ephakathi kwe 80 ne 90 yento nantoni na umntu oza kuyijonga. Ezantsi malunga ne 75 iindidi zezinto ezibonakalayo ziyaqala ukubonisa kwisikhumba, ilanga nakweyiphi na indawo enkulu ethe tyaba; ngaphezulu kwe 95 ifayile ikhula ngokukhawuleza ngelixa akukho mntu ubona utshintsho. Isicwangciso asiyophawu lomfanekiso, lugqibo malunga norhwebo lwangaphandle oluthile - ngoko khetha apho ifayile isiya khona, kwaye ugcine okuqala kwixesha elizayo xa ufuna impendulo eyahlukileyo.

Ingaba i-WebP igcina isiqalo esicacileyo?

Ewe - ifomati igcina isiqhagamshelanisi se-alpha, ngoko ilogo ecutiweyo, imifanekiso yemveliso kunye nokugqitywa gcina ukubonakala kwabo endaweni yokufika kwi-rectangle emnyama. Ukutshintsha kwifomati engenayo i-alpha kulapho i-alpha ihamba khona kakubi: iindawo ezibonakalayo zigqityiwe ngombala oqinileyo, ngokuqhelekileyo omnyama okanye omnyama, kwaye akukho ndlela yokubuyela umva efutshane yokufihla umxholo kwakhona.

Ingaba ixesha lesakhelo kunye nokuphindaphinda zihlala ziguqula i WebP?

Kwifomati ehlala ikhona i-frame enye kuphela ehlala, ngokuqhelekileyo i-first. Kwividiyo i-loop flag ayinakho ukuya apho, kuba umdlali ugqiba ukuba uphinde uphinde. Khangela ukudlala ngokukhawuleza emva kokuba i-frame rate itshintshile: i-rate ethe nkqo ingalingani kuphela ne-frame nganye eguqukayo i-delay.

Ingaba i WebP itsha kakhulu ukuba ixhaswe ngokubanzi?

Uncedo lwenkqubo yekhompyutha lwafika ngokukhawuleza; uncedo lwezixhobo zekhompyutha luza kuphela neesixhobo ezintsha, kwaye ifowuni, itelevisi okanye umdlali phambi kwakho ungasoloko ungaphambili. apho ixhaswe khona ingcono kakhulu kunefomati eyenza indawo, ngenxa yoko ixabiso lokuguqula kwi nikezelo kwaye ixabiso lokuguqula ngaphandle kokulungelelanisa.

Ingaba ikhamera nendawo ye-metadata igcinwa xa ndiguqula i-WebP?

Ithwala apho ifomati emiselweyo ixhasa khona - imodeli yekhamera, ukubonakala, ixesha lokuqwalasela, kunye ne GPS ikhowudi xa isixhobo sirekhoda. Lo mhla wokugqibela ufanele uthathelwe ingqalelo phambi koshicilelo: umfanekiso osuka kwifowuni uthatha indawo efanelekileyo.
