WebP ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-WebP ibe yi-PNG ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayile yakho WebP kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye PNG. Ukungabikho kolahleko PNG (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko PNG (JPG, WebP) ungalungisa umgangatho womsebenzi phambi kokukhuphela. I-WebP inikezela zombini iimeko ezilahlekileyo nezingalahlekileyo, ngokubonisa ngokucacileyo kwe-alpha noopopayi abafumanekayo kumnye. I-PNG isebenzisa uxinzelelo lwe-DEFLATE ngaphezulu kwamagqabantshintshi okuskena acociweyo, ngoko ke i-pixel nganye ihlala ngokuchanekileyo, kunye ne-8-bit epheleleyo ye-alpha channel.

Ingaba ukutshintsha WebP ukuya ku PNG kubuyisela ubunjani obulahlekileyo?

Hayi. Ii-artefacts zokucinezela eziphekwe kwi WebP zii-pixels zedata eziqhelekileyo ngoku, kwaye PNG igcina kakuhle kunokuba isuse. Ifayile ihlala ikhula, ngamanye amaxesha ikhula amaxesha amaninzi. Kubalulekile ukwenza phambi kohlela, kuba utshintsho oluthe kratya aluyi kunyusa udidi lwesibini lolahleko phezulu. I-PNG yinketho efanelekileyo yokuthatha imifanekiso yekhusi, ilogos, umzobo womgca nantoni na enemiphetho eqinileyo okanye ebonisa ngaphaya — akukho cingo, akukho mbala obandayo. I-WebP ihlala ikwinqanaba lesithathu ngaphandle komkhangeli zincwadi — ushicilelo lokuhamba komsebenzi, i-Office edala i-Office edala i-Office kunye nezinye ii-galeri zefowuni aziyi kuxhaswa.

Ingaba i PNG igcina i-EXIF data evela kum WebP?

Ngokungagqibekanga ewe, apho naphi na apho injongo ifuna ukubekwa khona - imodeli yekhamera, izicwangciso zokubonisa, iinwele kunye neGPS ikhowudi zihamba zonke. I-GPS yindawo efanele ucinga ngayo: ukuba umfanekiso uzakupapashwa, sebenzisa ukhetho lwe-strip-metadata ukuze ungasazibonisi apho umfanekiso uthathwe khona. I-WebP yifomati yomfanekiso yeGoogle ka-2010, eyenziwe kwi-VP8 keyframe encoder kwaye imiselwe ukubuyisela i-JPG, i-PNG ne-GIF ngaxeshanye.

I WebP yam iphila — yintoni eyenza ezinye ii-frames?

I-frame yokuqala kuphela ehlala, kuba PNG i-format ehlala ikhona engenanto yokugcina enye. Ukuba udweliso lubalulekile, cwangcisa i-format eyenza udweliso, okanye uguqule kwi-video container endaweni yoko ugcine intshukumo. I-PNG yifomati yomfanekiso ophantsi: umfanekiso ogciniweyo njenge-PNG uhlala ukhulu ngee-5 ukuya kwi-10 ngaphezu komfanekiso ofanayo njenge-JPG okanye i-WebP.

Ingaba uguqulelo WebP ukuya PNG lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa PNG i-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kokungasemva omhlophe. Ukuba ufuna ukubonakala ngaphaya kwiziphumo, cwangcisa ukubonakala ngaphaya okuziyo PNG endaweni ye-PNG=JPG. I-PNG yaphuhliswa ngowe-1996 njengento engekhoyo kwipateni ye-GIF, kwaye yayiyifomati yomfanekiso ongekhoyo kwi-web.

Ingaba iprofayili yam yombala (sRGB / Adobe RGB / CMYK) izakuhlala i WebP ukuya ku PNG?

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi WebP kwaye zidityaniswe kwakhona kwi-PNG apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga zibuyela kwi-sRGB, egcina imibala ihambelana nakwimboniselo eninzi yexesha elidlulileyo.

Yintoni malunga ne-EXIF metadata xa uguqula WebP ukuya PNG?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokumiselweyo ngexesha WebP → PNG xa zombini iifayili zixhasa i-metadata. Sebenzisa ukhetho lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kolwazi lwendawo.

Ndingaguqula iifayili ezininzi WebP zibe PNG ngaxeshanye?

Ewe - tsala iifayile ezininzi WebP kummandla wokulayisha kwaye sizibeke kwifolokhwe ngokuthe ngqo. Abasebenzisi abakhululekileyo bafumana i-100 MB kwifayili nganye; iPremium ayinalo icebo kwifayili nganye kwaye iqhuba abasebenzi abathe ngqo, ngoko ke umfanekiso we-200-iqela ligqiba ngaphantsi kwemizuzu emibini.

I-WebP ithelekiswa njani ne-PNG kwi-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati ethe ngqo siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imijelo yomhleli we desktop osebenzisa, ngemveliso efanayo yobunjani. Utshintsho luhamba ngaphaya kolawulo lweqela - iinkqubo ze desktop zivula ifayile enye ngexesha; siyamkela iqela.

Uphi ubungakanani obuzakubakho kwifayili yam PNG?

Okumiselweyo ku 1:1 — PNG wakho ugcina ubungakanani be-pixels yomthombo WebP. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva kokuguqula, okanye uyibeke kwi- /image-resize/ utility.

Ingaba i PNG incinane kangakanani na ukuba ingabonakali i-artifacts?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana PNG 60-80% omncinane kune-WebP ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-lossless PNG (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono.

Ingaba iifayile zam WebP zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayili ezilayishwe phezulu WebP ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe ngaphakathi kwemizuzu. Asiyi kufunda, sigcine ixesha elide, okanye sinikezele i-pixel data. Ifestile yokugcina epheleleyo ibhalwe kwi /privacy/.
