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.

Kwiziguqulelo ezininzi, iimayile ze-EXIF zekhamera ezinjengemodeli yekhamera kunye nendawo ye-GPS azithunyelwe kwi-WebP. Akukho mmiselo kule phepha ukugcina okanye ukususa i-metadata, ngoko khangela isiphumo ngombonisi we-metadata ukuba kubaluleke.

Ndingaguqula iifayili ezininzi PNG zibe WebP ngaxeshanye?

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

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 iifayile zam PNG zifihlakeleyo ngexesha lokuguqulwa?

Ewe. Iifayile ezilayishwe phezulu ze PNG ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe WebP kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

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.
