BMP kuya WebP Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho BMP futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomethi ye-WebP. 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-BMP igcina imiqulu ye-pixel engacindezelwanga ngokuphelele ngesihloko esincane, ngakho-ke kulula ukuyihlukanisa. I-WebP inikeza izimo ezilahlekile nezingenalahlekile, ngokukhanya kwe-alpha nokubukeka okutholakalayo kunoma yikuphi.

Ingabe ngizothola ukubukeka okucacile uma isithombe si WebP?

I-WebP isekela le fomethi, kodwa ukuguquka akukwazi ukuyenza. I-BMP ayinaso isixhumi se-alpha, ngakho wonke ama-pixels kufaka phakathi isizinda sifika sigcwele. Sebenzisa /removebackground/ ngemuva kokususa isithako — bese i-alpha channel WebP inikeza into egcinwa. I-WebP ivame ukuba 25-35% ncane kune-JPG elinganayo futhi ncane kune-GIF ephilayo, ngosizo lwesiphequluli esiphelele kusukela ngo-2020.

Ingabe ngizolahlekelwa yikhwalithi eningi uma ngisuka ku BMP 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 BMP njengenkosi futhi uphinde udale i WebP kusuka kuyo lapho ufuna ubukhulu obusha. I-BMP ayidingi i-decoder library ngaso sonke isikhathi, ngakho ihlala i-format ephephile yokushintshana yezinhlelo ezifakwe ngaphakathi neWindows ezidala.

Ingabe ukuguqulwa BMP kuya ku WebP kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho WebP 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-WebP. 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 BMP kuya ku WebP?

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

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

Yebo — cindezela amafayela amaningi BMP 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 BMP kuya ku WebP 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 WebP?

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

Ingabe ihele WebP lincane uma kungabonakali izinto ezibonakalayo?

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

Ingabe amafayela ami BMP afihlakele ngesikhathi sokuguqulwa?

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

Ingabe i-BMP kuya ku-WebP isebenza ngezithombe ezinkulu kakhulu (50MP+)?

Yebo, mahhala kuze kube yi-100 MB. I-Premium iphatha izingeniso ezinkulu kakhulu (300 MB+) kanye ne-exotic per-pixel depths (16-bit PNG, 32-bit float TIFF, HEIF 10-bit). Ipayipi lisakaza imikhawulo ye-pixel ngakho-ke inkumbulo isebenzisa izilinganiso ngenani lemikhawulo, hhayi inani le-pixel jikelele.
