- I-JPEG XL iyifomethi yesithombe ethuthukisiwe enikeza ukucindezelwa okuphezulu kakhulu kune-JPEG yendabuko kanye nokusekelwa kwasendaweni kwe-HDR.
- I-Chrome ihlanganise kabusha ukwesekwa kwamafayela e-.jxl kusetshenziswa i-decoder evikelekile ebhalwe ku-Rust ukuze kuthuthukiswe ukusebenza.
- Ivumela ukudluliselwa kwekhodi kwamafayela amadala e-JPEG ngaphandle kokulahlekelwa, kunciphisa usayizi wawo ngaphandle kokulahlekelwa yiphikseli eyodwa yekhwalithi.
Cishe uke wahlangana namafayela aphela ngo-.jxl futhi wawungazi ukuthi uzowenzani ngawo. Nokho, sikhuluma nge- JPEG XL , ifomethi yesithombe yesizukulwane esilandelayo elapha ukuze iguqule konke esikwaziyo. Akuyona nje isibuyekezo se-JPEG yakudala; uhlelo olusha ngokuphelele oluklanyelwe ukwenza amawebhusayithi asheshe kakhulu futhi izithombe zigcina ikhwalithi emangalisayo ngaphandle kokuthatha ingxenye yesikhala sakho se-hard drive.
Izindaba ezishaqisayo ukuthi i-Google Chrome isiphinde yamukela le fomethi , ihlanganisa ikhono lokuhlukanisa lezi zithombe ngendlela yazo. Ngemva kokungqubuzana okukhulu nokuphikiswana okukhulu ezweni lokuthuthukiswa, isiphequluli esivela ku-Mountain View giant sinqume ukuzibophezela kubuchwepheshe obuthembisa ukwenza amafomethi afana ne-WebP aphelelwe yisikhathi noma ngisho nokuncintisana ngqo ne-AVIF, ikakhulukazi uma kukhulunywa ngezithombe ezisezingeni eliphezulu.
Iyini ngempela ifomethi ye-JPEG XL?
Okokuqala, leli gama aliyona into eyenzekile ngengozi. Isifinyezo se-JPEG sivela ekomitini lochwepheshe bezithombe, u-X umele amazinga athuthukile, kanti u-L usho isikhathi eside , njengoba umgomo waso uwukuba yindinganiso eqondile amashumi eminyaka. Le fomethi ayiphazamisi: ivumela izithombe ezinesinqumo esikhulu, ezifinyelela kuma- terapixel , futhi isekela ukujula kombala okungafika kuma-bits angu-32 ngengxenye ngayinye.
Okwenza i-JXL ibe yitshe eliyigugu ngempela ukuthi iyakwazi ukuguquguquka. Ingaphatha kokubili ukucindezela okulahlekelwayo nokulahlekelwayo , isekela ukucaca (isiteshi se-alpha), futhi iyahambisana ne- High Dynamic Range (HDR) , into i-JPEG yakudala engayiphupha nje. Ngaphezu kwalokho, ingaphatha izithombe ezinyakazayo, okwenza kube yindlela enamandla yokusebenzisa ama-GIF noma i-WebP enyakazayo, kodwa ngokusebenza kahle okukhulu kakhulu.
Impi enkulu: i-JPEG XL ngokumelene ne-AVIF kanye ne-WebP
Uma uzibuza ukuthi kungani kufanele sisebenzise i-JPEG XL uma i-AVIF noma i-WebP isivele ikhona, impendulo ilele ezinombolweni. Uma kuqhathaniswa ne-JPEG yendabuko, i-JXL inganciphisa osayizi bamafayela ngo- 30% kuya ku-60% ngenkathi igcina ikhwalithi efanayo yokubuka. Uma iqhathaniswa ne-WebP, i-JXL iyenza kahle kakhulu cishe kuzo zonke izivivinyo, ikakhulukazi ezithombeni ezinemininingwane ephezulu lapho i-WebP ivame ukwehluleka khona.
Umncintiswano onzima kakhulu umelene ne-AVIF. Ngenkathi i-AVIF iphumelela kakhulu ekucindezelweni okunamandla (okuholela kumafayela amancane kakhulu), i-JPEG XL ishesha kakhulu ukufaka ikhodi . Lokhu kubalulekile kulabo abaphatha amakhathalogi amakhulu ezithombe. Ngaphezu kwalokho, i-JXL inikeza ukuqopha okuqhubekela phambili kwangempela ; okungukuthi, isithombe sivela kancane kancane ngokuningiliziwe kusukela ekuqaleni, kanti i-AVIF idinga ukuthi ifayela lilandwe cishe ngokuphelele ngaphambi kokuthi liqale ukuboniswa.
Indlela yokuvula izithombe ze-XL JPEG ku-Chrome
Uma unenguqulo ebuyekeziwe ye-Chrome (ikakhulukazi inguqulo 155 noma kamuva ), ukwesekwa kufanele kunikwe amandla ngokuzenzakalela ezinguqulweni zakamuva ezizinzile. Kodwa-ke, ngenxa yokuthi ifomethi idlule esigabeni sokuhlola, kungase kudingeke ukuthi uyivule ngesandla kwezinye izinguqulo.
Ukuze unike amandla ukwesekwa uma kungasebenzi, vele uthayiphe i-chrome://flags/#enable-jxl-image-format kubha yekheli . Uma usufikile, thola inketho ehambisanayo bese uyishintshela ku- Enabled . Ngemva kokuqala kabusha isiphequluli sakho, kufanele ukwazi ukubuka noma yiliphi ifayela le-.jxl olithola kuwebhu noma ulilayishe endaweni yangakini ngaphandle kwesidingo sokufaka noma yiziphi izinhlelo zangaphandle.
Izimfihlo zobuchwepheshe: Indima kaRust kanye nokushintsha ikhodi
I-Google ayikuthathanga kalula lokhu. Ukuze ivimbele isiphequluli ekubeni sengozini yokuhlaselwa yi-cyber, ibhale i-decoder ku- Rust . Lolu limi lokuhlela ludumile ngokuqinisekisa ukuphepha kwememori , lususa ubuthakathaka obuvamile abaphangi abavame ukubusebenzisa kuma-decoder abhalwe ku-C++. Umphumela uba isiphequluli esisheshayo futhi, ngaphezu kwakho konke, esiphephile kakhulu.
Kodwa kunesici esisodwa esiwumlingo nje: i-transcoding engenakulahlekelwa . I-JPEG XL ingathatha ifayela le-JPEG elidala futhi ililungiselele ukuthi libe lincane ngo-20% ngaphandle kokulahlekelwa ulwazi olulodwa. Ingxenye engcono kakhulu ukuthi inqubo iyaguqulwa; ungabuyela ku-JPEG yokuqala njengoba yayinjalo. Lesi isipho sabathwebuli bezithombe nabanikazi bewebhusayithi abangafuni ukucubungula kabusha izinkulungwane zezithombe kusukela ekuqaleni.
Umthelela ekusebenzeni kwewebhu kanye ne-Core Web Vitals
Kulabo kini abathanda kakhulu i-SEO kanye nesivinini sokulayisha amakhasi, i-JPEG XL ingumngani omkhulu. Ngokunciphisa usayizi wesithombe esiyinhloko (i-LCP, noma i-Largest Contentful Paint), amakhasi alayisha ngokushesha kakhulu , ikakhulukazi ekuxhumaneni kweselula okuhamba kancane. Ngenxa yokubhala ikhodi okusebenzayo okusebenzisa imiyalelo yehadiwe ye-SIMD, iprosesa yeselula ayisebenzi kanzima, ithuthukisa ukushelela kokuphequlula jikelele.
Nakuba ukwesekwa komhlaba wonke kusalinganiselwe uma kuqhathaniswa ne-JPEG, lo mkhuba ucacile. Njengoba i-Safari isiyisekele isikhathi esithile futhi i-Chrome isivele ikhona, uhlelo lwe-ecosystem luqhubekela phambili kule nqubo. Ukusebenzisa isici se-HTML <picture> okwamanje kuyisu elihle kakhulu: kukuvumela ukuthi unikeze ifayela le-.jxl kulabo abangalifunda futhi ushiye i-JPEG yakudala njengendlela yokubuyela emuva noma enye indlela yeziphequluli ezindala.
Le fomethi entsha imelela igxathu elidingekayo lokuziphendukela kwemvelo kuwebhu, ihlanganisa ukucindezela okunamandla nokuthembeka okubonakalayo okumangalisayo kanye nokuphepha okuthuthukisiwe ngenxa yeRust. Amandla ayo okunciphisa kakhulu osayizi bamafayela esithombe kanye nesici sayo esisha sokuguqula ikhodi kuyenza ibe ithuluzi eliphelele lokwenza ngcono ulwazi lomsebenzisi kanye nokusebenza kobuchwepheshe kwanoma iyiphi iwebhusayithi yesimanje.
