WebP ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-WebP ibe yi-BMP ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayili yakho ye WebP, emva koko umguquli wethu ufaka ukuphuculwa komgangatho owaziyo wefomati ye-BMP imveliso. Kwifomati ezingalahlekiyo (PNG, TIFF, BMP) sigcina zonke ii-pixels; kwifomati ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho phambi kokukhuphela.

Ingaba ukubonakaliswa okubonakalayo kuya kuqhubeka nokutshintsha WebP ukuya ku BMP?

Hayi - BMP ayinasiqhagamshelanisi se-alpha, ngoko imimandla ecacileyo idityaniswe nombala wokungasemva, omnyama ngaphandle kokuba uyitshintshile. Oku kubangela uxinzelelo oluqhelekileyo oluthile kule kuguqulelo: ilogo ebonakala icocekile kwiphepha elimnyama lifika ngebhokisi emhlophe ejikelezayo. Misela umbala omnyama ukuze uthelekise apho umfanekiso uhlala khona, okanye khetha injongo egcina i-alpha. I-BMP inamandla amakhulu — umfanekiso we-12-megapixel ujikeleze i-36 MB — kwaye akukho mkhangeli zincwadi uyamphatha njengefomati yewebhu esebenzayo.

Ingaba ukutshintsha WebP ukuya ku BMP kubuyisela ubunjani obulahlekileyo?

Hayi. Ii-artefacts zokucinezela eziphekwe kwi WebP zii-pixels zedata eziqhelekileyo ngoku, kwaye BMP igcina kakuhle kunokuba isuse. Ifayile ihlala ikhula, ngamanye amaxesha ikhula amaxesha amaninzi. Kubalulekile ukwenza phambi kohlela, kuba utshintsho oluthe kratya aluyi kunyusa udidi lwesibini lolahleko phezulu. I-BMP ayifuni i-decoder library, ngoko ihlala ikhuselekile kwifomati yotshintshiselwano lweenkqubo ezifakelweyo kunye nezixhobo zeWindows ezihlala zikhona. I-WebP ihlala ikwinqanaba lesithathu ngaphandle komkhangeli zincwadi — ushicilelo lokuhamba komsebenzi, i-Office edala i-Office edala i-Office kunye nezinye ii-galeri zefowuni aziyi kuxhaswa.

Ingaba i BMP igcina i-EXIF data evela kum WebP?

Ngokungagqibekanga ewe, apho naphi na apho injongo ifuna ukubekwa khona - imodeli yekhamera, izicwangciso zokubonisa, iinwele kunye neGPS ikhowudi zihamba zonke. I-GPS yindawo efanele ucinga ngayo: ukuba umfanekiso uzakupapashwa, sebenzisa ukhetho lwe-strip-metadata ukuze ungasazibonisi apho umfanekiso uthathwe khona. I-WebP yifomati yomfanekiso yeGoogle ka-2010, eyenziwe kwi-VP8 keyframe encoder kwaye imiselwe ukubuyisela i-JPG, i-PNG ne-GIF ngaxeshanye.

I WebP yam iphila — yintoni eyenza ezinye ii-frames?

I-frame yokuqala kuphela ehlala, kuba BMP i-format ehlala ikhona engenanto yokugcina enye. Ukuba udweliso lubalulekile, cwangcisa i-format eyenza udweliso, okanye uguqule kwi-video container endaweni yoko ugcine intshukumo.

Ingaba uguqulelo WebP ukuya ku BMP lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa usiya kwi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kwesiqalo esimhlophe - ukuba ufuna ukubonakala ngaphaya, cwangcisa ifomati eyaziyo ukubonakala ngaphaya endaweni ye-BMP.

Ingaba i-inkangeleko yam yombala (sRGB / Adobe RGB / CMYK) iya kuhlala i WebP ukuya ku BMP?

Iiprofayili zombala we-ICC ezifakelweyo zifundwa kumvelaphi WebP kwaye zidityaniswe kwakhona kwi-BMP yemveliso apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga zibuyela kwi-sRGB.

Yintoni malunga ne-EXIF metadata xa uguqula WebP ukuya ku BMP?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS) igcinwa ngokumiselweyo ngexesha lokuguqulwa kwe-WebP → BMP xa zombini iifayili zixhasa i-metadata. Sebenzisa ukhetho lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kolwazi lwendawo.

Ndingaguqula izigidi zeefayili WebP zibe BMP ngaxeshanye?

Ewe — tsala iifayile ezininzi WebP kwindawo yokulayisha kwaye sizibeke kwifolokhwe ngokuthe tye. Abasebenzisi abakhululekileyo bafumana i-100MB ngefayili nganye; i-Premium ayinasiphelo sefayili nganye kwaye iqhuba abasebenzi abathe tye abaninzi, ngoko ke iqela lemifanekiso engama-200 ligqiba ngaphantsi kwemizuzu emibini.

I-WebP ukuya kwi-BMP ithelekiswa njani ne-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati olulula siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop usebenzisa, ngexabiso elifanayo. Utshintsho luyizinto ze desktop zivula ifayile enye ngexesha; siyamkela iqela kwaye siqhuba ngokuthe tye.

Ingaba i-BMP iya kuba nesisombululo esinjani na?

Ukuziphatha okungagqibekanga kuku-1:1 — i-BMP yakho yemveliso inezinto ezilinganayo ze-pixels njenge-WebP. Sebenzisa /resize-image/ inyathelo elahlukileyo emva kokuguqula ukuba ufuna ukunyusa okanye ukunyusa i-scale njengenxalenye yokuhamba komsebenzi.

Ingaba i BMP ifayili incinane kangakanani na ukuba ayinazo izinto ezibonakalayo ezibonakalayo?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana ifayili i-60-80% incinane kune-WebP yomthombo ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwiinjongo ezingalahlekiyo (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono.

WebP

I-WebP inika ucinezelo olungcono kakhulu olungenalahleko nolungenalahleko kwimifanekiso ekwiwebhu, oluphuhliswe yiGoogle.

BMP

Iifayile zeBMP zigcina imifanekiso kwifomathi yebitmap engacinezelwanga, nto leyo ebangela ukuba iifayile zibe nkulu kodwa zibe nomgangatho ogqibeleleyo.
