Indlela yokuguqula BMP kuya WebP

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

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

Isinyathelo 3: Landa i-version yakho WebP amafayela

BMP kuya WebP Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho BMP, bese isiguquli sethu sifaka ukulungisa umgangatho okwaziyo ifomethi ye-WebP. Ifomethi engalahleki (PNG, TIFF, BMP) sigcina wonke ama-pixel; ifomethi elahlekile (JPG, WebP) ungahlela umphumela womgangatho ngaphambi kokufaka.

Ingabe ngizothola ukubukeka okucacile uma isithombe si WebP?

Ifomethi WebP isekela lokhu, kodwa ukuguqulwa akukwazi ukukwenza. BMP ayikho i-alpha channel, ngakho wonke ama-pixel kufaka phakathi isizinda sifika ngokugcwele esimnyama. Sebenzisa /image-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. I-WebP inikeza izimo ezilahlekile nezingenalahlekile, ngokukhanya kwe-alpha nokubukeka okutholakalayo kunoma yikuphi.

Yini mayelana ne-EXIF metadata uma uguqula BMP usuka ku-WebP?

Kuzo zonke izishintsho, ama-EXIF ama-camera afana nemodeli ye-camera nendawo ye-GPS afakwanga ku-WebP. Akukho sinqumo kule khasi sokugcina noma ukususa i-metadata, ngakho hlola imiphumela ngombonisi we-metadata uma kubaluleke.

Ingabe ngingenza ukuguqulwa kwekhulu le BMP amafayela ku WebP ngasikhathi sinye?

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

Yini isixazululo kanye nezici zehele lami WebP?

Ukuziphatha okuzenzakalelayo yi-1:1 — i-WebP yakho yesokudla inezici ze-pixel ezifanayo ne-BMP. Sebenzisa isikhashana /ukuguqula-isifanekiso/ esisodwa ngemuva kokuguqulwa uma ufuna ukuncipha noma ukuphakama njengengxenye yokuhamba komsebenzi.

Ingabe ihele WebP lincane uma kungabonakali izinto ezibonakalayo?

I-JPG / WebP, ikhwalithi engu-75-85 ithola ihele elincincane ngama-60-80% kunalomthombo BMP ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Inhloso engalahleki (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono.

Ingabe amafayela ami BMP afihlakele ngesikhathi sokuguqulwa?

Yebo. Amafayela BMP alayishwe phezulu aphathwa kumaseva ethu ahlukile futhi angeke abone noma ahlukaniswe. Amafayela alayishwe phezulu namasithombe aguqulwe asuswa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa. Inqubomgomo yobumfihlo egcwele itholakala ku /privacy/.
