PNG ukuba WebP Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayile yakho PNG kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye WebP. Ukungabikho kolahleko WebP (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko WebP (JPG, WebP) ungalungisa umgangatho womsebenzi phambi kokukhuphela. 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. I-WebP inikezela zombini iimeko ezilahlekileyo nezingalahlekileyo, ngokubonisa ngokucacileyo kwe-alpha noopopayi abafumanekayo kumnye.

Ingaba ndiya kulahlekelwa yintoni ngomgangatho xa ndisuka kwi PNG ukuya kwi WebP?

Kwi umgangatho 80- 85 utshintsho alubonakali kumgama wokubona oqhelekileyo kwaye ifayile ihlala iphantsi nge 60- 80%. Ukubamba kukuba yindlela enye: ukubuyisela ukugcina i WebP ngokuphindaphinda idibanisa i artefacts ixesha ngalinye. Gcina i PNG njenge master kwaye uphinde uphinde uvule i WebP ukusuka kuyo xa ufuna ubungakanani obutsha. I-PNG yinketho efanelekileyo yokuthatha imifanekiso yekhusi, ilogos, umzobo womgca nantoni na enemiphetho eqinileyo okanye ebonisa ngaphaya — akukho cingo, akukho mbala obandayo.

Ingaba uguqulelo PNG ukuya WebP lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa WebP 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 WebP endaweni ye-WebP=JPG. I-WebP yifomati yomfanekiso yeGoogle ka-2010, eyenziwe kwi-VP8 keyframe encoder kwaye imiselwe ukubuyisela i-JPG, i-PNG ne-GIF ngaxeshanye.

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

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi PNG kwaye zidityaniswe kwakhona kwi-WebP 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 PNG ukuya WebP?

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

Ndingaguqula iifayili ezininzi PNG zibe WebP ngaxeshanye?

Ewe - tsala iifayile ezininzi PNG 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-PNG ithelekiswa njani ne-WebP 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 WebP?

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

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

Kwi-JPG / WebP, umgangatho we-75-85 ufumana WebP 60-80% omncinane kune-PNG ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-lossless WebP (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono. I-WebP ihlala i-25-35% incinane kune-JPG elinganayo kwaye incinci kune-GIF ephilayo, enesixhaso se-browser esipheleleyo ukusukela ngo-2020.

Ingaba iifayile zam PNG zifihlakeleyo ngexesha lokuguqulwa?

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

Ingaba i-PNG ukuya kwi-WebP iguqulela isebenza kwimifanekiso emikhulu kakhulu (50MP+)?

Ewe, simahla ukuya kwi-100 MB. I-Premium iphatha izingeniso ezinkulu (300 MB+) kunye nobunzulu obungenakulinganiswa kwi-pixel nganye (16-bit PNG, 32-bit float TIFF). I-pipeline ijikelezisa imiqolo ukuze ukusetyenziswa kovimba weefayili kulinganiswe ngobalo lomqolo, hayi ubalo lwee-pixels ezipheleleyo.

Kutheni i WebP yam eguqulweyo ikhula okanye incinci kuneleyo ndiyifumeneyo?

A PNG nge-compression enamandla ekhoyo (i-lossy JPG) ihlala ikhula xa iphinde ikhowudiwe kwi-lossless WebP (PNG, TIFF). I-lossless PNG ihlala ikhula ngokugqithisileyo xa isiya kwi-JPG / WebP. Uthelekiso luxhomekeke kwizinto eziqulethe umfanekiso - iimifanekiso zicofa ngokuhlukileyo kumfanekiso womgca. I-PNG yifomati yomfanekiso ophantsi: umfanekiso ogciniweyo njenge-PNG uhlala ukhulu ngee-5 ukuya kwi-10 ngaphezu komfanekiso ofanayo njenge-JPG okanye i-WebP. 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.
