UGoogle upapashe imisebenzi enxulumene ifomathi entsha yokulinga yokufaka ikhowudi ebizwa ngokuba yi "WebP 2", ethi ikhule njenge ukubuyiselwa ngokufanelekileyo kwifomathi yeWebhu.
Ukusukela ifomathi entsha isaphuhlisweni kwaye ayichazwanga ekugqibeleni, ayikakulungeli ukusetyenziswa ngokubanzi (Ukudibana ngasemva akuqinisekiswanga kwisikhowudi kunye nekhowudi, ikhowudi ayilungiswanga.)
Malunga neWebhu 2
En I-WebP 2 ichaza amanqaku amatsha okuphumeza, njenge-HDR ngemibala emalunga ne-10-bit, Ukunyanzeliswa kokusebenza kolwazi olungafihlisiyo, Inkxaso epheleleyo yoopopayi, ukucazululwa ngokulula kokulula (ukucazulula umaleko-ngeenkcukacha ezithe kratya kwinqanaba ngalinye, ukuvumela ukuba uvelise izithombisi ngokukhawuleza ukujonga kwangaphambili), ukuphunyezwa kwesoftware enemisonto emininzi, ukunciphisa ukuthotywa okubonakalayo kumazinga asezantsi eebits, imowudi yoxinzelelo yokungaphulukani nelahleko.
I-WebP 2 ngumlandeli kwifomathi yomfanekiso weWebP, okwangoku kuphuhliso. Ayilungelanga ukusetyenziswa gabalala kwaye ifomathi ayigqitywanga, ke utshintsho kwilayibrari lunokwaphula inkxaso yemifanekiso ebhalwe ngasemva.
Le phakheji iqulethe ilayibrari enokusetyenziswa kwezinye iinkqubo zokufaka ikhowudi okanye ukucacisa imifanekiso yeWebp 2, kunye nezixhobo zomgca wokuyalela.
Injongo yale fomathi intsha iyafana naleyo ye-WebP yokuqala: Ukuhanjiswa kwemifanekiso kwinethiwekhi, ukulungiswa kwezigqibo eziphakathi, ukusetyenziswa kwewebhu kunye nokusetyenziswa kweselfowuni, ngenkxaso yemisebenzi eqhelekileyo yale misebenzi, enje ngenkxaso yokwenza izinto elubala, oopopayi kunye nemizobo ekhawulezileyo.
Uvavanyo lweWebP 2 codec ikakhulu iqhuba amanqaku eWebP ngokubhekisele kuxinzelelo. Iimpawu ezintsha (ezinje ngenkxaso ye-10b HDR) zigcinwa ubuncinci. Izembe lokulinga zezi:
Ukucinezelwa kokulahleka okungaphezulu (~ 30% ngcono kuneWebhu, kufutshane ne-AVIF ngokusemandleni)
Ukonakala okubonakalayo okungcono kwi-bitrate esezantsi kakhulu
Ukuphuculwa koxinzelelo lwelahleko
Ukuphuculwa kokubonisa ngokucacileyo
Inkxaso yoopopayi
Ukujonga kwangaphambili kwe-Ultralight
Ukukhanya kokunyuka kokukhanya
Isikhongozeli esincinci esincinci, esenzelwe ngokukodwa uxinzelelo loMfanekiso
Uyilo olupheleleyo lwe-10-bit (HDR10)
Ukugxila ngokuqinileyo kuphumezo lwesoftware, efundwe ngokupheleleyo
Amatyala okusetyenziswa ahlala ikakhulu efana neWebP: ukuhanjiswa kweentambo, iiwebhu ezikhawulezayo, usetyenziso oluncinci, amava angcono omsebenzisi… IWebP 2 ubukhulu becala ilingana nesiqulatho esiqhelekileyo esifumaneka kwiwebhu nakwizicelo zeselfowuni: ubukhulu bobubanzi obuphakathi, ukungafihli, oopopayi abafutshane, iithonjana.
Eyona migudu iphambili kuphuhliso lwefomathi entsha Injongo yokwandisa ukusebenza koxinzelelo.
Okokuqala iWebP ifezekisa ukunciphisa ubungakanani befayile ukusuka kwi-25% ukuya kwi-34% xa kuthelekiswa neefayile ze-JPEG ezikumgangatho ofanayo, kunye nakwimowudi yokulahleka okungafunekiyo, ifezekisa ukuncipha kwama-26% kubungakanani befayile xa kuthelekiswa nenqanaba lokucinezelwa lePNG. I-WebP 2 ijolise ekuphuculeni ukusebenza ngokufanelekileyo Uxinzelelo lwama-30% xa kuthelekiswa ne-WebP yokuqala kwaye uzisa i-AVIF yokulahleka kwekhowudi yokucinezela kwi-20%.
Iprototype ephantsi kovavanyo ayisebenzi kakuhle kwaye iwela emva emva kokuphunyezwa kwe-libwebp ngokwekhowudi kunye nesantya sokumisa. Umzekelo, kwimowudi yoxinzelelo, I-WebP 2 yenza ucinezelo amaxesha amahlanu kancinci kune-WebP yokuqala.
Xa kuthelekiswa ne-libavif, ifomathi entsha yeWebP yintoni le ikhulayo Iikhowudi zikaGoogle ziphindwe kabini ngokukhawuleza, kodwa isala amaxesha ama-3 kwisantya sokumisela. Kwangelo xesha, ngeli xesha kukhutshwa uguqulelo lokugqibela lwethala leencwadi le-libwebp2, kucwangcisiwe ukufezekisa umlinganiso kwisantya sokumisela.
Okokugqibela, kwabo banomdla wokwazi ngakumbi malunga nenqaku, banokujonga kupapasho lwantlandlolo Kule khonkco ilandelayo.
Kwaye abo banomdla wokwazi ikhowudi yeprojekthi, kunye nenkqubela phambili yayo, banokuyifumana ngokuya kuyol ukulandela ikhonkco.
