WebP ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye WebP kwaye umguquli wethu usebenzise ukuphuculwa komgangatho owaziyo ifomati ye BMP imveliso. Kwiinjongo ezingalahlekiyo (PNG, TIFF, BMP) yonke i-pixel igcinwa nge-bit-per-bit; kwiinjongo ezilahlekiyo (JPG, WebP) ungalungisa isizathu somgangatho (okungagqibekanga 90) phambi kokukhuphela. I-WebP inikezela zombini iimeko ezilahlekileyo nezingalahlekileyo, ngokubonisa ngokucacileyo kwe-alpha noopopayi abafumanekayo kumnye. I-BMP igcina imiqolo ye-pixel engacinezelwanga ngokupheleleyo enesihloko esincinci, oko kukuthi, yintoni eyenza kube lula ukuchaza ngeenkcukacha.

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 BMP yi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha ukuba yi-JPG kwenza ukuba isiqhagamshelanisi se-alpha sifane nesiqalo esimhlophe — ukuba ufuna ukubonakala ngaphaya, khetha isiphelo esizimelayo esibonisa ngaphaya endaweni ye-BMP. I-BMP yi-Windows Bitmap, ifomati ye-raster egqityiweyo eyenziwe kwi-Windows ukusukela ngo-1985.

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 yiprofayili zibuyela kwi-sRGB ngenyathelo elilula lokuqinisekiswa.

Ithini into ebangela ukuba i-EXIF metadata iguqulwe WebP ibe yi BMP?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS) igcinwa ngokumiselweyo ngexesha WebP -> BMP xa zombini iifayili zixhasa i-metadata. Sebenzisa utshintshi lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kokubekwa kwendawo okanye ukubonisa umnwe wesixhobo.

Ndingaguqula izigidi zeefayili WebP zibe BMP ngaxeshanye?

Ewe - rhuqa iifayile ezininzi WebP kwindawo yokulayisha kwaye zifolole ngokuthe tye. Umphakamo osimahla uyamkela i-100 MB 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 asebenzisayo, kwi umgangatho ofanayo. Utshintsho kukuba izixhobo ze desktop zivula ifayile enye ngexesha; siyamkela iqela kwaye siqhuba ngokuthe tye kwiseva- ecaleni kwabasebenzayo.

I-BMP iifayili zinee-resolutions kunye nemilinganiselo eziphi?

Ukuziphatha okungagqibekanga kuku 1:1 — i-BMP yakho yemveliso inezinto ezilinganayo ze-pixels njenge-WebP. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva, okanye ubeke iinzame kwi- /image-pipeline/ utility.

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

Kwi-JPG / WebP, umgangatho we-75-85 uhlala uvelisa i-BMP 60-80% encinci kune-WebP ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-BMP engenanto (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono kuneleyo umboneleli sele uneyo.
