WebP kuya BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho WebP futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomethi ye-BMP. 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-BMP igcina imiqulu ye-pixel engacindezelwanga ngokuphelele ngesihloko esincane, ngakho-ke kulula ukuyihlukanisa.

Ingabe ukubukhali kuzoqhubeka nokushintsha WebP kuya ku BMP?

Akuna - BMP ayikho i-alpha channel, ngakho amasifunda abonisa ngaphaya ahlanganisane nombala wesizinda, omhlophe uma ungashintsha. Lokhu kuyinto ejwayelekile kakhulu enjalo: ilogo ebukeka ihlanzekile kukhasi elimnyama lifika ngebhokisi elimhlophe libhekene nalo. Misela umbala omnyama ukuze ulinganise lapho isithombe sihlala khona, noma khetha okudingayo okugcina i-alpha. I-BMP iyinto enkulu—isithombe esingu-12-megapixel siyizi-36 MB—nakho akukho isiphequluli esiyiphatha njengefomethi yewebhu efanele.

Ingabe ukushintsha WebP kuya ku BMP kuzobuyisela ubunjani obulahlekile?

Akukho. Izinto ezicindezelwe ezifakwe ku WebP manje ziyidatha ye-pixel ejwayelekile, futhi BMP 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-BMP ayidingi i-decoder library ngaso sonke isikhathi, ngakho ihlala i-format ephephile yokushintshana yezinhlelo ezifakwe ngaphakathi neWindows ezidala. I-WebP ihlala iyisikole sesithathu ngaphandle kwesiphequluli — ukuphrinta komsebenzi, ama-Office adala futhi ezinye izimboni zefoni azikwazi ukuwuvuma.

Ingabe i-BMP 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 BMP iyifomethi ehlala khona engenandawo yokugcina okushiwo. Uma udwebo lubalulekile, bheka ifomethi edlalayo, noma uguqule ibe yividiyo equkethe isithombe futhi ugcine ukunyakaza.

Ingabe ukuguqulwa WebP kuya ku BMP kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho BMP 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-BMP. I-BMP yiWindows Bitmap, ifomethi ye-raster engaqondakali efakwe ku-Windows kusukela ngo-1985.

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

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

Ikhamera EXIF (ISO, ishutter, ilensi, GPS) igcinwa ngokuzenzakalela ngesikhathi WebP -> BMP 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 BMP 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 BMP 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 BMP?

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

Ingabe ihele BMP lincane uma kungabonakali izinto ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuletha i-BMP 60-80% encane kune-WebP ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless BMP (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono kune-source esenayo.
