Ngati mwakhala mukulumikizana kwambiri ndi intaneti, mwina mwazindikira kuti zina mwazinthu zazikulu zomwe zimapanga intaneti monga zithunzi ndi maulalo zadutsa pakusintha kwazaka khumi zapitazi. Intaneti ndi yachangu, komanso yotetezeka pang’ono. Tawona kusintha kwakukulu pazithunzi pa intaneti, kuchokera ku WebP, AVIF, ndipo tsopano Jpegli, laibulale yatsopano yojambulira zithunzi yomwe Google posachedwapa. kumasulidwa. Ndiye ndi chiyani kwenikweni ndipo chifukwa chiyani zili zofunika? Tiyeni tifufuze.
Kodi Jpegli ndi chiyani?
Jpegli ndi laibulale yatsopano yotsegulira ya JPEG ya Google yomwe cholinga chake ndi kuchepetsa kwambiri kukula kwa ma JPEG ndikusungabe chithunzicho ndikupewa zinthu zakale zomwe nthawi zambiri mumazipeza pazithunzi zothinikizidwa. Mawu akuti “li” kumapeto amatanthauza “wamng’ono” m’zinenero za ku Swiss German.
Ndilo tanthauzo lakumbuyo-logwirizana zithunzi za Jpegli zitha kutsegulidwa ndi mapulogalamu omwe amathandizira ma JPEGs, angathandize chepetsani kukula kwa chithunzi chokhazikika cha JPEG ndi 35%ndi kugwiritsa ntchito 10+ bits pachigawo chilichonse m’malo mwa njira zachikhalidwe za JPEG zomwe zimangopereka ma bits 8 pachigawo chilichonse. Ndi bwino kwambiri.
Jpegli ndi pang’ono pang’ono bwino kuposa WebP chifukwa cha psinjika yake yofulumira komanso yapamwamba kwambiri. Ikhoza kusunga zosungirako pamene ikufulumizitsa nthawi zolemetsa zamasamba.
Kodi Jpegli Imagwira Ntchito Motani?
Pachimake, Jpegli amagwiritsa ntchito zinthu zinayi zofunika kuti akwaniritse kupsinjika kwambiri popanda kugunda bwino. Ndi Adaptive Quantization, Kusankhidwa Kwa Matrix Kwabwino, Mawerengedwe Olondola, ndi Optional Advanced Colorspace.
Quantization Yokhazikika mu JPEGs ndiye chifukwa chachikulu cha khalidwe lawo lapakati. Jpegli amagwiritsa ntchito adaptive quantization, yomwe, m’mawu a layman, imasintha zomwe zili pachithunzichi zomwe ziyenera kusungidwa kutengera zigawo zazithunzi. Izi potero amachepetsa phokoso ndikusunga tsatanetsatane pamene akukwaniritsa 35% compression. Jpegli amatenga gawo la izi kuchokera m’mabuku a laibulale ina yotchuka yotseguka yotchedwa JPEG XL.
Google imachitcha “Kusintha malo akufa” kutengera mawonekedwe ake a psychovisual mu imodzi mwama projekiti ake otchedwa Butteraugli. Pulojekitiyi imathandizira kuyerekezera kufanana pakati pa zithunzi ziwiri ndi momwe timaziwonera pozipatsa scalar score ndikukonzekera mapu a malo a msinkhu wa kusiyana.
Pakuyesa kwa Google, Jpegli adapeza zambiri kuposa malaibulale achikhalidwe monga a Mozilla MozJPEG ndi libjpeg-turbo. M’mawu osavuta, izi zikutanthauza kuti Jpegli imatha kupondaponda zithunzi bwino kwambiri kuposa nsanja zina zolembera.
Kodi Jpegli Amatanthauza Chiyani pa Webusaiti?
Palibe. Webusaiti, makamaka, yatenga ma WebPs. Kuti mumvetse bwino kusiyana kwa WebP ndi Jpegli, lingalirani WebP ngati sutikesi ndipo Jpegli ndi chikwama cha duffel chokwezeka. Sutukesi imakupatsani mwayi wosunga Zithunzi zopindidwa bwino kuti muwonetsetse kuti zili bwino kwambiri koma onyamula onse sangazindikire sutikesiyo.
Kumbali ina, Jpegli ndikukweza ku chikwama chanu chakale cha duffel (JPEG). Imagwiritsa ntchito njira zanzeru zopondereza mafayilo pomwe amazindikiridwa ndi onyamula (owonera omwe alipo a JPEG). M’mawu osavuta, WebP ndi mtundu wazithunzi pomwe Jpegli ndi encoder/decoder ya mtundu wa JPEG.
Ndiye, intaneti iyamba kugwiritsa ntchito Jpegli posachedwa? Ayi, chifukwa idatengera kale ma WebP ambiri. Komabe, yembekezerani Jpegli kugwiritsidwa ntchito mu zida zosiyanasiyana zopangira zithunzi zomwe zimapereka magwiridwe antchito. Magawo a intaneti omwe amagwiritsabe ntchito ma JPEG atha kugwiritsa ntchito Jpegli kupanga masamba mwachangu, koma momwe zilili pano, ma WebP azilamulira zinthu zapaintaneti kwazaka zambiri kuchokera pano.
Ma JPEG amatha kugwiritsa ntchito encoding ya Jpeglis, koma sitingadziwe chifukwa zithunzizo zikadakhalabe mumtundu wa JPEG. Mtundu wa fano la WebP, kumbali ina, uli pano kuti ukhalepo chifukwa umakhala wosunthika kwambiri ndikuthandizira kukanikiza ma PNG, zithunzi zamakanema, komanso kuwonekera kwa alpha.
Maganizo anu ndi otani pa laibulale yatsopano ya Jpegli yotulutsidwa ndi Google? Tiuzeni mu ndemanga pansipa.
