I-Safari 17 ne-WebKit zisekela ifomethi yesithombe se-JPEG XL

I-Apple inikeze amandla ngokuzenzakalela ezinguqulweni ze-beta zesiphequluli se-Safari 17 kanye nokusekelwa kwenjini ye-WebKit yefomethi yesithombe se-JPEG XL, i-Google elahle ukusekelwa ku-Chrome ngonyaka odlule. Ku-Firefox, ukusekela kwefomethi ye-JPEG XL kuyatholakala ngokwakhiwa kwasebusuku (kunikwe amandla nge-image.jxl.enabled = true in about:config), kodwa i-Mozilla ihlala ingathathi hlangothi ekuphromotheni le fomethi okwamanje.

Ukuntuleka kwentshisekelo eyanele ye-ecosystem kufomethi kuphawulwe njengempikiswano yokususa usekelo lokuhlola lwe-JPEG XL kusukela ku-Chromium codebase. Kusukela lapho, isimo sishintshile futhi ngaphezu kwempendulo enhle evela kubathuthukisi bewebhu kanye nomphakathi (abamele i-Facebook, Adobe, Intel ne-VESA, Krita, The Guardian, libvips, Cloudinary, Shopify kanye neFree Software Foundation bakhulume ngokusekela i-JPEG XL ku-Chrome), ifomethi manje izosekelwa ku-Safari. I-Google iyaqhubeka nokuthola izicelo ezihlobene nokubuyiselwa kwekhodi yokusebenzisa i-JPEG XL ku-Chromium.

Izimpikiswano ze-Google ezimelene nokufakwa kwe-JPEG XL ziphinde zafaka nokuntuleka kwezinzuzo ezengeziwe ezanele kumafomethi akhona. Nokho, ikhasi lokufaka isicelo sokwengeza usekelo lwe-JPEG XL enjinini ye-Blink likhuluma ngezinzuzo ezinjengokuncipha kosayizi ofika ku-60% uma kuqhathaniswa nezithombe ze-JPEG zekhwalithi efanayo nokuba khona kwezici ezithuthukisiwe njenge-HDR, ukugqwayiza, ukubonakala, ukulayisha okuqhubekayo. imodi, ukuwohloka okushelelayo kwekhwalithi nokuncipha kwe-bitrate, ukucindezelwa kwe-JPEG okungalahleki (kunciphisa usayizi we-JPEG kuze kufike ku-21% ngekhono lokubuyisela isimo sangempela), ukusekelwa kweziteshi ezifika ku-4099 kanye nobubanzi obubanzi bokujula kombala.

Ikhodekhi ye-JPEG XL ayinanzuzo futhi inikeza ukuqaliswa kwereferensi evulekile ngaphansi kwelayisensi ye-BSD. Ubuchwepheshe obusetshenziswa ku-JPEG XL abushayisani nobuchwepheshe obunelungelo lobunikazi, ngaphandle kwelungelo lobunikazi le-Microsoft lendlela ye-rANS (range Asymmetric Number System), kodwa kule lungelo lobunikazi iqiniso lokusetshenziswa kwangaphambilini (“ubuciko bangaphambili”) likhonjiwe.
