Indlela yokuguqula WebP kuya BMP

Isinyathelo 1: Layisha eyakho WebP amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

Isinyathelo 3: Landa i-version yakho BMP amafayela

WebP kuya BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho WebP futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomu le BMP. Ukungabi nalutho BMP (PNG, TIFF, BMP) wonke ama-pixel agcinwa; ukungabi nalutho BMP (JPG, WebP) ungalungisa umphumela womgangatho ngaphambi kokulayisha. 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 WebP kuya ku BMP ukuguqulwa kugcina ukubukeka okucacile?

Ukubukeka okucacile kuqhubeka uma BMP 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 BMP endaweni ye-BMP=JPG. I-BMP yiWindows Bitmap, ifomethi ye-raster engaqondakali efakwe ku-Windows kusukela ngo-1985.

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

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

Ikhamera EXIF (ISO, i-shutter, i-lens, GPS coords) igcinwa ngokuzenzakalela ngesikhathi WebP → BMP 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 BMP 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 BMP 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 BMP?

Okuzenzakalelayo yi-1:1 — BMP 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 BMP ingancane uma ingabonakali i-artifacts?

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