U-Apple ukhiphe izindaba ezimbili ezinkulu
Muva nje kumenyezelwe ukuthi i-Apple ivumele ukwesekwa okuzenzakalelayo kwefomethi yesithombe se-JPEG XL ku-beta ye-Safari 17 kanye nenjini ye-WebKit, i-Google eyayiyeke ukuyisekela ku-Chrome ngonyaka odlule.
I-Google ithathe njengengxabano yokususa usekelo lokuhlola lwe-JPEG XL ku-Chromium codebase, ukuntuleka kwentshisekelo eyanele kufomethi ye-ecosystem. Izimpikiswano ze-Google eziphikisana nokufakwa kwe-JPEG XL ziphinde zaveza ukushoda kwezinzuzo ezengeziwe ezanele kumafomethi akhona.
Kusukela ngaleso sikhathi, isimo sishintshile futhi ngaphezu kwempendulo enhle evela kubathuthukisi bewebhu kanye nomphakathi, ifomethi manje izohambisana neSafari.
Ngasikhathi sinye, ikhasi lokufaka isicelo sokwengeza ukusekelwa kwe-JPEG XL enjinini ye-Blink likhuluma ngezinzuzo ezinjengokuncishiswa kosayizi kufika ku-60% uma kuqhathaniswa nezithombe ze-JPEG zekhwalithi efanayo kanye nokuba khona kwezici ezithuthukile njenge-HDR, ukugqwayiza, ukubonakala obala, ukulayisha okuqhubekayo, ukuwohloka okushelelayo ngokuncishiswa kwe-bitrate, ukuminyanisa okungalahleki kwe-JPEG (kufika ku-21% ukuncipha kwe-JPEG nekhono lokubuyisela isimo sangempela), ukusekelwa kwamashaneli afinyelela kwangu-4099, kanye nohlu olubanzi lokushona kwesithombe. umbala.
Esinye isici esihle se-codec ye-JPEG XL ukuthi ayinayo imali yokubhalisa futhi inikeza ukusetshenziswa okuvulekile kokubhekisela ngaphansi kwelayisensi ye-BSD. Ubuchwepheshe obusetshenziswa ku-JPEG XL abuhambisani nobuchwepheshe obuzimele, ngaphandle kwelungelo lobunikazi le-Microsoft lendlela ye-rANS (Rank Asymmetric Number System); noma kunjalo, ukusetshenziswa kwaleli lungelo lobunikazi kwangaphambilini kuye kwadalulwa.
Ngaphezu kwalokho, imiphumela yanyatheliswa ngokuqhathanisa amafomethi e-JPEG XL, WebP, kanye ne-AVIF kusetshenziswa isevisi ye-ImageEngine . Ukufaka ikhodi kwe-JPEG XL kwehlise osayizi bamafayela ngo-11% uma kuqhathaniswa ne-AVIF, futhi ekuhlolweni kwe-Data Service Standard (DSSIM), i-JPEG XL idlule i-AVIF ngo-13%. Ngokuphathelene ne-WebP, amanani ayo ajwayelekile aseduze ne-AVIF, okusho ukuthi i-JPEG XL nayo iphambili ngo-10% ngokwesilinganiso sokucindezela kanye nezinga lomehluko obonakalayo kusukela kowokuqala.
Ku-Firefox, ukwesekwa kwe-JPEG XL kuyatholakala ezakhiweni zasebusuku (kunikwe amandla nge-` image.jxl.enabled=true` ku-`about:config` ), kodwa i-Mozilla ayithathi hlangothi ekukhuthazeni ifomethi okwamanje. Okwamanje, i-Google iyaqhubeka nokuthola izicelo zekhodi yokubuyisela ukuze i-JPEG XL isebenze ku-Chromium.
Ukugqugquzela
Izisusa eziyinhloko zokusekela i-JPEG XL ku-Chrome yilezi:
- Ukuthuthukiswa kwekhwalithi yesithombe uma kuqhathaniswa nosayizi wesithombe, ukonga cishe okungu-60% kusayizi wefayela wekhwalithi efanayo yokubonwayo (ukucindezela okulahlekile kwemibhalo yokuqala emikhulu) uma kuqhathaniswa ne-JPEG ngezimfanelo ezizithola kuwebhu.
Ukubambezeleka okubonakalayo okuthuthukisiwe ngosayizi abancane bokulanda kanye nezindlela eziqhubekayo zokukhipha amakhodi.
- Ukusekelwa kwe-HDR, ukugqwayiza nokuthuthuka, konke kuhlangene kukhodekhi yesithombe esifanayo.
- Ukusekelwa kwamafayela e-JPEG acindezelwe kabusha angalahleki
Okokugcina, kubalulekile futhi ukuqaphela ukuthi i-Apple yethule i-Game Porting Toolkit ku-WWDC23, okuhloswe ngayo ukuvumela abathuthukisi bemidlalo ye-Windows ukuthi badlulise imidlalo yabo ukuze isebenze ku-macOS.
Kulokhu, kufanelekile ukusho ukuthi ikhodi yomthombo yephrojekthi isekelwe ku-Wine enezinye iziqeshana ze-CodeWeavers ezisetshenziswa ekuhleleni iphakheji ye-CrossOver yesikhulumi se-macOS.
I-Game Porting Toolkit isebenzisa inguqulo ye-CrossOver engu-22.1.1, enikeza ikhono lokusebenzisa imidlalo ngokusekelwe kuma-API e-DirectX 10 kanye ne-11 ku-macOS. Iphrojekthi ikhulume ngokuthi ukwesekwa kokuqala kwe-DirectX 12 kuhlelelwe inguqulo yesikhathi esizayo ye-CrossOver 23 ye-macOS.
Uma unesithakazelo sokufunda kabanzi ngesethulo se-Game Porting Toolkit, ungathola imininingwane kusixhumanisi esilandelayo.
