WebP kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho WebP futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomethi ye-PNG. 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-WebP inikeza izimo ezilahlekile nezingenalahlekile, ngokukhanya kwe-alpha nokubukeka okutholakalayo kunoma yikuphi. I-PNG isebenzisa ukucindezeleka 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 ukuguqulwa WebP kuya ku PNG kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho PNG 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-PNG. I-PNG yakhiwa ngo-1996 njengento eshintshayo engekho emthethweni ye-GIF, futhi yashintsha ibe yifomethi yesithombe esingenalutho esizenzakalelayo se-web.

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

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka kumthombo WebP futhi axhunywe kabusha ku-PNG 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 WebP usuka ku-PNG?

Ikhamera EXIF (ISO, ishutter, ilensi, GPS) igcinwa ngokuzenzakalela ngesikhathi WebP -> PNG 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 WebP amafayela ku PNG ngasikhathi sinye?

Yebo — cindezela amafayela amaningi WebP 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 WebP kuya ku PNG iqhathaniswa kanjani ne-Photoshop / GIMP ngemisebenzi efanayo?
