JPEG XL chimiro che raster mifananidzo. Inopa kurasikirwa kwekumanikidza modhi pamwe nekusarasikirwa kwekumanikidza modhi
Munguva pfupi yapfuura yakazozivikanwa ruzivo nezve chinyorwa muGoogle bug tracker yeChromium-based browsers inojekesa kuti Chrome vhezheni 110 pakupedzisira haizotsigire JPEG XL.
jpeg xl iri raster mufananidzo fomati inobvumira kudzvanywa kwemifananidzo ichiri nekurasikirwa kana pasina. JPEG XL yakagadzirirwa kuve inoshanda zvakanyanya kupfuura mafomati aripo uye ine chinangwa chekuatsiva kune ese akajairika kushandiswa.
Iyo yakanyanya kukosha fomati yemifananidzo yekuchengetedza mafoto yakapemberera kwayo makore makumi matatu mwedzi mishoma yapfuura. JPEG inotova nevatsivi vakati wandei vanogadzirisa matambudziko ayo, asi hapana akawana mukurumbira parizvino. JPEG chete ndiyo inotsigirwa pasi rose nemabhurawuza ewebhu nguva dzose, editing software, nharembozha uye makamera.
Mutsivi ane musoro aifanira kunge ari JPEG 2000, asi haina kumbobata. Microsoft yakanga ichigadzira JPEG XR inovimbisa, asi ivo vaive nemvumo pairi, uye pavakavhura iyo fomati, yakanga isisanakidze. Kusvikira Google yauya pamwe ne Android neChrome kuzosimudzira VP8 yakavakirwa vhidhiyo compression WebP. WebP yaive makumi ezana muzana inoshanda kupfuura JPEG uye yakatsigirwa alpha chiteshi (pachena), kusarasikirwa nekumanikidza, uye mifananidzo, saka yaigona zvakare kutsiva PNG neGIF.
Mafomati eRaster, kune rumwe rutivi, anosarurwa kuratidza akaomesesa zvimiro zvine akawanda asina kujairika maumbirwo uye ruzivo. Kugadzirazve mufananidzo, raster mafomati anokodha iwo ega ega epixel mune rectangular grid. Asi, mapikicha akawanikwa munyaya iyi ane hunhu hunosiririsa hwekukanganiswa kana kubvondoka kana wawedzerwa. Nekuda kweizvi, dzimwe nguva zvakakosha kuchengetedza akawanda mavhezheni emufananidzo we raster mune akasiyana zvigadziriso kuti uve nechokwadi chechokwadi chekubhurawuza.
Nhasi, WebP inoenderana neese makuru desktop uye mobile browser. Semuenzaniso, muna Ndira 2019, Mozilla yakazivisa kuti Firefox 65 ikozvino inotsigira WebP. Microsoft yakaita chiziviso chimwe chete cheEdge browser yayo muna Gumiguru 2018. Google yakanga yatozivisa muna 2011 kuti sevhisi yeemail yeGmail, Picasa yekugovera mafoto sevhisi, uye Chrome browser zvino yaizoshandisa iyo kodhi-yakavakirwa WebP mufananidzo compression fomati.
Nepo WebP yakashandiswa zvakanyanya pawebhu, haishandiswe kumwe kumwe. Semuenzaniso, haina kukodzera kuchengetedza mapikicha emhando yepamusoro, sezvo ichiri kugumira ku8-bit color chiteshi uye haitsigire HDR.
Kutsiva JPEG neHEIC zvinoreva kuti kutora mafoto pa iPhone kana iPad kunotora nzvimbo shoma pane yako iripo yekuchengetedza. Mufananidzo weHEIC unotora inenge hafu yenzvimbo yeJPEG yakaenzana uye inosangana nezvakawanda zveinotevera-chizvarwa chinodiwa kutora mafoto. Semuenzaniso, nekuchengetedza data kubva ku3D mapikicha akabatwa neazvino maPhones, mapikicha maapplication anogona kugadzira yakakosha mhedzisiro inotamba kubva kumashure kweselfie yako.
Kubva Android 10, HEIC inotsigirwawo neGoogle. Asi HEIC iri pasi perezinesi rakasimba, saka haishandiswe pawebhu.
Naizvozvo, mubatanidzwa weAOMedia wemakambani makuru etekinoroji akafungidzira imwe nzira yeAVIF (yakavakirwa paAV1 vhidhiyo), yaiita kunge ndiyo Holy Grail. Inogona kutsiva JPEG, PNG, uye GIF, zvakare inotsigira 12-bit color, HDR, uye kupfuura zvese, ndeyemahara uye haina kuvharwa nematendi. Chrome, Firefox uye iyo itsva Safari 16 yatotsigira AVIF, asi Microsoft ichiri kuifuratira muEdge, kunyangwe ichibatanidzwawo mukusimudzira kwayo senhengo yeAOMedia. Nekudaro, haiburitse chero chinhu zvakananga kuAVIF, zvese zvirimo zvinofanirwa kushandurwa ipapo.
Kuita kuti zvinhu zviwedzere kuipa, JPEG XL yakagadzirwa mumakore matatu apfuura, chirongwa chinosanganisira vanyori vekutanga JPEG, asiwo Google. Iyo zvakare yemahara fomati inokwanisa kutsiva PNG neGIF, inovimbisa yakakwirira-mhando uye inoshanda kudzvanya uye zvakare isingarasikirwe shanduko yeJPEG, iyo inochengetedza ingangoita makumi maviri muzana yedata pasina kurasikirwa chero ruzivo rwemufananidzo. JPEG XL yakazoita sechimwe chinhu icho indasitiri yaigona kubvumirana pazviri.
Chrome, Edge, uye Firefox yakawedzera rutsigiro rwekuyedza chirimo chapfuura uye zvinhu zvese zvaifamba zvakanaka. Asi Google yakashamisika mazuva mashoma apfuura payakamisa JPEG XL uye ikati haichaverengerwa muChromium 110 uye gare gare. Izvo hazvisati zvajeka kuti Microsoft, iyo yakavakirwa Edge paChromium, ichaita sei, asi pane mukana wakanaka uchave nemhedzisiro.
Panguva imwecheteyo, Google haidi kuunza kupatsanurwa kwakawanda, saka yakazivisawo kuti WebP 2 yairi kugadzirira, iyo yaifanirwa kuunza zviri nani mhando yemifananidzo, haizoburitswa sechimiro chemufananidzo. Iyo kambani ichashanda papurojekiti, asi ichaonekwa seyakawanda sepuratifomu yebvunzo.
