I-JPEG XL yifomati yemifanekiso yeraster. Inika imowudi yokucinezela ilahleko kunye nemowudi yocinezelo engalahlekiyo
Kutshanje kuye kwaziwa ulwazi malunga nenqaku kwiGoogle bug tracker yeChromium-based browsers icacisa ukuba i-Chrome version 110 ekugqibeleni ayiyi kuxhasa iJPEG XL.
jpeg xl yi ifomati yomfanekiso weraster ovumela ucinezelo lwemifanekiso emileyo ngelahleko okanye ngaphandle. I-JPEG XL iyilelwe ukuba isebenze ngakumbi kuneefomati ezikhoyo kwaye ijolise ekubuyiseleni kuzo zonke izinto eziqhelekileyo.
Eyona fomati yomfanekiso ibalulekileyo yokugcina iifoto ibhiyozele iminyaka engama-30 kwiinyanga ezimbalwa ezidlulileyo. I-JPEG sele inabalandeli abaninzi abalungisa iingxaki zayo, kodwa akukho namnye ofumene ukuthandwa. Kuphela yiJPEG exhaswa jikelele ziziphequluli zewebhu eziqhelekileyo, isofthiwe yokuhlela, iifowuni eziphathwayo kunye neekhamera.
Umlandeli onengqiqo kufuneka abe yiJPEG 2000, kodwa ayizange ibambe. UMicrosoft wayephuhlisa iJPEG XR ethembisayo, kodwa babenamalungelo omenzi kuwo, kwaye xa bevula ifomathi, yayingasenamdla. Kude kube uGoogle weza kunye ne-Android kunye neChrome ukukhulisa Uxinzelelo lwevidiyo olusekwe kwiVP8 WebP. I-WebP yayingamashumi eepesenti esebenzayo ngakumbi kuneJPEG kunye ne-alpha channel exhaswayo (i-transparency), ukunyanzeliswa okungalahlekiyo, kunye neepopayi, ngoko ke inokuthi ithathe indawo ye-PNG kunye ne-GIF.
Iifomathi zeRaster, kwelinye icala, zikhethwa ekuboniseni imiboniso entsonkothileyo enemilo emininzi engaqhelekanga kunye neenkcukacha. Ukuvelisa kwakhona umfanekiso, iifomathi ze-raster zifakela amaxabiso epikseli nganye kwigridi yoxande. Kodwa, imifanekiso efunyenwe kulo mzekelo inento engathandekiyo yokugqwetheka okanye imfiliba xa yandiswa. Ngenxa yoku, ngamanye amaxesha kubalulekile ukugcina iinguqulelo ezininzi zomfanekiso we-raster kwizisombululo ezahlukeneyo ukuqinisekisa amava okukhangela afanelekileyo.
Namhlanje, IWebP iyahambelana nazo zonke iidesktop ezinkulu kunye nezikhangeli ezihambayo. Umzekelo, ngoJanuwari 2019, iMozilla yabhengeza ukuba iFirefox 65 ngoku iyayixhasa iWebP. I-Microsoft yenza isaziso esifanayo kwi-browser yayo ye-Edge ngo-Okthobha ka-2018. UGoogle wayesele ebhengeze ngo-2011 ukuba inkonzo ye-imeyile ye-Gmail, inkonzo yokwabelana ngefoto ye-Picasa, kunye ne-Chrome browser ngoku iza kusebenzisa i-code-based based format compression image.
Ngelixa iWebP isetyenziswa kakhulu kwiwebhu, ayisetyenziswa kwenye indawo. Umzekelo, ayifanelekanga ukugcina iifoto ezikumgangatho ophezulu, njengoko isanqandelwe kwi-8-bit yemibala yetshaneli kwaye ayixhasi i-HDR.
Ukutshintsha iJPEG nge-HEIC kuthetha ukuba ukuthatha iifoto kwi-iPhone okanye kwi-iPad kuya kuthatha indawo encinci kakhulu kwindawo yakho yokugcina. Ifoto ye-HEIC ithatha malunga nesiqingatha sesithuba seJPEG ekumgangatho olinganayo kwaye ihlangabezana nezo mfuno zokufota zesizukulwana esilandelayo. Umzekelo, ngokugcina idatha evela kwimifanekiso ye-3D ebanjwe ngee-iPhones ezintsha, ii-apps zeefoto zinokwenza iziphumo ezikhethekileyo ezidlala ngasemva kwe-selfie yakho.
Ukusukela kwi-Android 10, i-HEIC ikwaxhaswa nguGoogle. Kodwa i-HEIC iphantsi kwelayisensi engqongqo, ngoko ke ayisetyenziswa kwiwebhu.
Ke ngoko, umanyano lwe-AOMedia yeenkampani ezinkulu zetekhnoloji zabona enye indlela kwi-AVIF (esekelwe kwividiyo ye-AV1), ebonakala ngathi yiGrail eNgcwele. Ingathatha indawo yeJPEG, PNG, kunye ne-GIF, ikwaxhasa i-12-bit umbala, i-HDR, kwaye ngaphezu kwayo yonke into, isimahla kwaye ayigqunywanga ngamalungelo awodwa abenzi. I-Chrome, iFirefox kunye neSafari 16 entsha sele ixhasa i-AVIF, kodwa iMicrosoft isayihoya kwi-Edge, nangona ibandakanyeka kuphuhliso lwayo njengelungu le-AOMedia. Nangona kunjalo, ayikhupheli nto ngokuthe ngqo kwi-AVIF, wonke umxholo kufuneka uguqulwe apho.
Ukwenza izinto zibe zibi nakakhulu, iJPEG XL yadalwa kwiminyaka emithathu edlulileyo, iprojekthi ebandakanya ababhali beJPEG yasekuqaleni, kodwa kunye neGoogle. Ikwayifomati yasimahla ekwaziyo ukutshintsha i-PNG kunye ne-GIF, ithembisa ucinezelo olukumgangatho ophezulu kunye nolusebenzayo kunye noguqulo olungalahlekiyo lweJPEG, olugcina malunga ne-20% yedatha ngaphandle kokuphulukana nolwazi lomfanekiso. IJPEG XL ekugqibeleni yabonakala ngathi yinto enokuvumelana noshishino.
IChrome, iEdge, kunye neFirefox zongeze inkxaso yovavanyo kwintwasahlobo edlulileyo kwaye yonke into yayihamba kakuhle. Kodwa uGoogle wothukile kwiintsuku ezimbalwa ezidlulileyo xa wayeka iJPEG XL kwaye wathi ayisayi kuphinda ifakwe kwiChromium 110 kwaye kamva. Akukacaci ukuba iMicrosoft, esekwe kwi-Edge kwiChromium, iya kuhamba njani, kodwa kukho ithuba elihle lokuba kubekho umphumo.
Ngelo xesha, iGoogle ayifuni ukuzisa ukuhlukana okungaphezulu, ngoko ke yazisa ukuba iWebP 2 yayilungiselela, eyayifanele ukuzisa umgangatho womfanekiso ongcono, ayiyi kukhutshwa njengefomathi yomfanekiso nokuba. Inkampani iya kusebenza kwiprojekthi, kodwa iya kuthathwa njengeqonga lovavanyo.
