PNG kuya WebP Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-PNG ibe yi-WebP ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho PNG futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomethi ye-WebP. Kuzo zonke izimo ezingenalutho (PNG, TIFF, BMP) wonke ama-pixel agcinwa nge-bit-by-bit; kuzo zonke izimo ezingenalutho (JPG, WebP) ungalungisa i-quality factor (iphutha 90) ngaphambi kokufaka ngezansi. I-PNG isebenzisa ukucindezeleka kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele. I-WebP inikeza izimo ezilahlekile nezingenalahlekile, ngokukhanya kwe-alpha nokubukeka okutholakalayo kunoma yikuphi.

Ingabe ngizolahlekelwa yikhwalithi eningi uma ngisuka ku PNG ngiye ku WebP?

Kukhwalithi engu-80-85 ushintsho alubonakali kude kakhulu kokubheka futhi ifayela liphansi ngo-60-80%. Ukwesaba ukuthi kuyindlela eyodwa: ukulondoloza kabusha i WebP phinda phinda ihlanganise ama-artefacts ngaso sonke isikhathi. Gcina i PNG njengenkosi futhi uphinde udale i WebP kusuka kuyo lapho ufuna ubukhulu obusha. I-PNG iyisinqumo esifanele sezithombe-skrini, amalogo, umdwebi we-line kanye nanoma yini eneziphetho eziqinile noma ezicacile — akukho ukusakaza, akukho umbala obandayo.

Ingabe ukuguqulwa PNG kuya ku WebP kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho WebP i-PNG, WebP, TIFF, GIF, noma i-SVG. Ukushintsha ibe yi-JPG kuzoba ne-alpha channel efana nendawo yangasemva ebomvu — uma ufuna ukubukeka okucacile, khetha okuzokwazi ukubukeka okucacile endaweni ye-WebP. WebP Google 2010 isithombe ifomu, eyenziwe kusuka VP8 keyframe encoder futhi inhloso ukushintsha JPG, PNG ne GIF ngasikhathi sinye.

Ingabe iprofayili yami yombala (sRGB / Adobe RGB / CMYK) izohlala i PNG kuya ku WebP?

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka kumthombo PNG futhi axhunywe kabusha ku-WebP lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi enza i-profayili ayixhasi ibuyela emuva ku-sRGB nge-soft-proof step.

Yini ekwenzeke ku-EXIF metadata uma uguqula PNG usuka ku-WebP?

Ikhamera EXIF (ISO, ishutter, ilensi, GPS) igcinwa ngokuzenzakalela ngesikhathi PNG -> WebP lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukushintsha ubumfihlo ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokutholakala kwendawo noma idivayisi-fingerprint.

Ingabe ngingenza ukuguqulwa kwekhulu le PNG amafayela ku WebP ngasikhathi sinye?

Yebo — cindezela amafayela amaningi PNG endaweni yokulayisha futhi babeke ifile ngokufanayo. Isigaba esimahhala sithatha ama-100 MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza ngemisebenzi eminingi efana, ngakho-ke isithombe esingu-200 siqedela ngezansi kwemizuzu emibini.

Ingabe PNG kuya ku WebP iqhathaniswa kanjani ne-Photoshop / GIMP ngemisebenzi efanayo?

Ukuguqulwa kwefomethi elula sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efana ne-desktop editor esebenzisa, ngekhwalithi efanayo. Ushintsho ukuthi amathuluzi wedesktop avula ifayela elinye ngasikhathi sinye; sivumela iqembu futhi sisebenzisana nabo kubasebenzi bekhasimende.

Yini isixazululo kanye nezici zehele WebP?

Ukuziphatha okuzenzakalelayo yi-1:1 — i-WebP yakho yesokudla inezici ze-pixel ezifanayo ne-PNG. Uma ufuna ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva, noma ubeke izinhlelo nge- /image-pipeline/ utility.

Ingabe ihele WebP lincane uma kungabonakali izinto ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuletha i-WebP 60-80% encane kune-PNG ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless WebP (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono kune-source esenayo. I-WebP ivame ukuba 25-35% ncane kune-JPG elinganayo futhi ncane kune-GIF ephilayo, ngosizo lwesiphequluli esiphelele kusukela ngo-2020.

Ingabe amafayela ami PNG afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu PNG aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukufunda, ukugcina, noma ukuhlanganisa idatha ye-pixel. Ifasitela eligcwele lokugcinwa libhalwe ku /privacy/.

Ingabe i-PNG kuya ku-WebP isebenza ngezithombe ezinkulu kakhulu (50MP+)?

Yebo, mahhala kuze kube yi-100 MB. I-Premium iphatha izingeniso ezinkulu kakhulu (300 MB+) kanye ne-exotic per-pixel depths (16-bit PNG, 32-bit float TIFF, HEIF 10-bit). Ipayipi lisakaza imikhawulo ye-pixel ngakho-ke inkumbulo isebenzisa izilinganiso ngenani lemikhawulo, hhayi inani le-pixel jikelele.

Kungani ihele lami eliguqulwe WebP likhulu noma lincane kunalokho okulindelekile?

Ihele PNG elinamandla okucindezeleka (JPG enamandla okulahlekelwa) livame ukukhula uma liphinde likhodwe ku WebP (PNG, TIFF) elingalahlekelwa, futhi i-bitrate ephezulu engenalutho PNG livame ukuncipha kakhulu uma liya ku-JPG/WebP. Ukulingana kuxhomekeka kusithombe esiqukethwe (izithombe zicindezelwa ngendlela eyahlukileyo kunaleyo ye-line-art noma izithombe zeskrini). I-PNG iyifomethi yesithombe esibi: isithombe esigcinwe njenge-PNG sivame ukuba likhulu izikhathi eziyisithupha kuya kweziyishumi kunesithombe esifanayo njenge-JPG noma i-WebP. I-WebP ihlala iyisikole sesithathu ngaphandle kwesiphequluli — ukuphrinta komsebenzi, ama-Office adala futhi ezinye izimboni zefoni azikwazi ukuwuvuma.

PNG

Amafayela we-PNG asebenza ngokucacile futhi asebenzisa ukucindezeleka okungalahleki, okwenza kube ngcono kakhulu kuma-graphic, amalogo, nama-screenshots.
