WebP kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho WebP futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomu le PNG. Ukungabi nalutho PNG (PNG, TIFF, BMP) wonke ama-pixel agcinwa; ukungabi nalutho PNG (JPG, WebP) ungalungisa umphumela womgangatho ngaphambi kokulayisha. I-WebP inikeza izimo ezilahlekile nezingenalahlekile, ngokukhanya kwe-alpha nokubukeka okutholakalayo kunoma yikuphi. I-PNG isebenzisa ukucindezelwa kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele.

Ingabe ukushintsha WebP kuya ku PNG kuzobuyisela ubunjani obulahlekile?

Akukho. Izinto ezicindezelwe ezifakwe ku WebP manje ziyidatha ye-pixel ejwayelekile, futhi PNG igcina kahle kunesisusa. Ihele livame ukukhula, ngamanye amaxesha likhula izikhathi eziningi. Kuyinto efanele ukuyenza ngaphambi kokuhlela, ngoba ukuhlela okulandelayo akuzofaka isizukulwane sesithathu sokulimala phezulu. I-PNG iyisinqumo esifanele sezithombe-skrini, amalogo, umdwebi we-line kanye nanoma yini eneziphetho eziqinile noma ezicacile — akukho ukusakaza, akukho umbala obandayo. I-WebP ihlala iyisikole sesithathu ngaphandle kwesiphequluli — ukuphrinta komsebenzi, ama-Office adala futhi ezinye izimboni zefoni azikwazi ukuwuvuma.

Ingabe i-PNG igcina i-EXIF data kusuka ku-WebP yami?

Ngokungajwayelekile yebo, lapho injongo ikhona khona ukuze ibekwe khona - imodeli yekhamera, izilungiselelo zokuveza, ilensi kanye ne-GPS coordinates zonke zihamba phambili. I-GPS iyindawo efanele ukucabanga ngayo: uma isithombe sizoshicilelwa, sebenzisa i-strip-metadata option ukuze ungasakazi lapho isithombe sithathwe khona. WebP Google 2010 isithombe ifomu, eyenziwe kusuka VP8 keyframe encoder futhi inhloso ukushintsha JPG, PNG ne GIF ngasikhathi sinye.

I WebP yami iphila — yini ekwenzeke kwezinye ifreyimu?

Ifreyimu yokuqala kuphela ehlala, ngoba PNG iyifomethi ehlala khona engenandawo yokugcina okushiwo. Uma udwebo lubalulekile, bheka ifomethi edlalayo, noma uguqule ibe yividiyo equkethe isithombe futhi ugcine ukunyakaza. I-PNG iyifomethi yesithombe esibi: isithombe esigcinwe njenge-PNG sivame ukuba likhulu izikhathi eziyisithupha kuya kweziyishumi kunesithombe esifanayo njenge-JPG noma i-WebP.

Ingabe WebP kuya ku PNG ukuguqulwa kugcina ukubukeka okucacile?

Ukubukeka okucacile kuqhubeka uma PNG i-PNG, WebP, TIFF, GIF, noma SVG. Ukushintsha ku-JPG kwenza i-alpha channel ibe mhlophe. Uma ufuna ukubukeka okucacile esinqumweni, bheka ukubonakala okucacile okuqaphelayo PNG endaweni ye-PNG=JPG. I-PNG yakhiwa ngo-1996 njengento eshintshayo engekho emthethweni ye-GIF, futhi yashintsha ibe yifomethi yesithombe esingasebenzisi iphutha ye-web.

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

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundeka kusuka ku-WebP futhi axhunywe kabusha ku-PNG lapho ifomu lixhasa khona (JPG, PNG, TIFF, WebP). Amafomu enza iphrofayli ayixhasi ubuyela emuva ku-sRGB, okugcina amamibala ahambisana nemboniso yamanje.

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

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

Ingabe ngingakwazi ukushintsha amafayela amaningi WebP abe PNG ngasikhathi sinye?

Yebo — cindezela amafayela ahlukahlukene WebP endaweni yokulayisha bese siwafaka emgodini ngokufanayo. Abasebenzisi abamahhala bathola i-100 MB ngefayela ngalinye; iPremium ayinaso isikhala ngasinye sefayela futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngezansi kwemizuzu emibini.

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

Ukuguqulwa kwefomethi eqondile sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efana ne-desktop editor, ngekhwalithi yokuphuma efana. Ushintsho luyi-batch parallel handling — desktop applications open one file at a time; we accept a batch.

Yini isixazululo esizobe sikhona kuhele PNG?

Okuzenzakalelayo yi-1:1 — PNG yakho igcina ama-pixels alinganayo we-WebP. Uma ufuna ukuguqula ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva kokuguqulwa, noma uyibeke nge /image-resize/ utility.

Ingabe i PNG ingancane uma ingabonakali i-artifacts?

Ingabe amafayela ami WebP afihlakele ngesikhathi sokuguqulwa?

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

WebP

I-WebP inikeza ukucindezela okungcono kakhulu okungenakulahlekelwa nokungalahleki kwezithombe eziku-inthanethi, okwakhiwe yi-Google.

PNG

Amafayela e-PNG asekela ukucaca futhi asebenzisa ukucindezela okungenakulahlekelwa, okwenza afaneleke kakhulu kuma-graphics, ama-logo, kanye nezithombe-skrini.
