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 ufaka ukulungisa umgangatho okwaziyo ifomethi ye WebP. U WebP ongalahleki (PNG, TIFF, BMP) wonke ama-pixel agcinwa; u WebP ongelahleki (JPG, WebP) ungahlela umphumela womgangatho 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 ku-JPG kuhlanganiswa isixhumi se-alpha esibhekene nesizinda esimhlophe. Uma ufuna ukubukeka okucacile esinqumweni, bheka ukubonakala okucacile okuqaphelayo WebP endaweni ye WebP=JPG. 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 ku-PNG futhi axhunywe kabusha ku-WebP lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi ngaphandle kwe-inkxaso yeprofayili abuyela emuva ku-sRGB, ogcina amamibala ahambisanayo phakathi kweziboniso eziningi ezimanje.

Yini mayelana ne-EXIF metadata uma uguqula PNG usuka ku-WebP?

Ikhamera EXIF (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokuzenzakalela ngesikhathi PNG → WebP lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokubeka indawo.

Ingabe ngingenza ukuguqulwa kwe-batch kwe-PNG amafayela amaningi ku-WebP ngasikhathi sinye?

Yebo — cindezela amafayela amaningi PNG endaweni yokulayisha futhi sizowabeka emqoka ngokufanayo. Abasebenzisi abamahhala bathola i-100 MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngaphantsi kwemizuzu emibini.

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

Ukuguqulwa kwefomethi eqondile sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efanayo umhleli wedesktop asebenzisayo, ngekhwalithi yokuphuma efanayo. Ushintsho luyi-batch management ehambisanayo — ama-desktop apps avula ifayela elinye ngasikhathi sinye; sivuma i-batch.

Yini isixazululo sehele lami WebP?

Iphutha ngu 1:1 — WebP yakho igcina ama-pixels ama-dimensions we-PNG. Uma ufuna ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva kokuguqulwa, noma uyibeke nge /image-resize/ utility.

Ingabe i WebP ingaba ncane ngaphandle kwezinto ezibonakalayo ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuthola i-WebP 60-80% encane kuna-PNG ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless WebP (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono. 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 isikhathi eside, 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 (300 MB+) kanye ne-exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). Ipayipi lisakaza imibhalo ukuze umsebenzisi wememori alinganise ngokubalwa kwemibhalo, hhayi inani eliphelele le-pixel.

Kungani i-WebP yami eguqulwe ibe mkhulu noma ncane kunalokho engilindele?

A PNG nge-compression ekhona enamandla (JPG elahlekile) ivame ukukhula uma iphinde ikhodwe ku-lossless WebP (PNG, TIFF). A lossless PNG ivame ukuncipha kakhulu uma ihamba ku-JPG / WebP. Isilinganiso sixhomekeke kusithombe esiqukethwe — ama-photos acindezelwa ngendlela eyahlukileyo kunaleyo ye-line art. 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 ahambisana nokubukeka okucacile futhi asebenzisa ukucindezeleka okungalahleki, okwenza kube ngcono kakhulu kuma-graphic, amalogo, nama-screenshots.
