WebP ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayile yakho WebP kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye BMP. Ukungabikho kolahleko BMP (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko BMP (JPG, WebP) ungalungisa umgangatho womsebenzi 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 BMP lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa BMP i-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kokungasemva omhlophe. Ukuba ufuna ukubonakala ngaphaya kwiziphumo, cwangcisa ukubonakala ngaphaya okuziyo BMP endaweni ye-BMP=JPG. I-BMP yi-Windows Bitmap, ifomati ye-raster egqityiweyo eyenziwe kwi-Windows ukusukela ngo-1985.

Ingaba iprofayili yam yombala (sRGB / Adobe RGB / CMYK) izakuhlala i WebP ukuya ku BMP?

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi WebP kwaye zidityaniswe kwakhona kwi-BMP apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga zibuyela kwi-sRGB, egcina imibala ihambelana nakwimboniselo eninzi yexesha elidlulileyo.

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

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

Ndingaguqula iifayili ezininzi WebP zibe BMP ngaxeshanye?

Ewe - tsala iifayile ezininzi WebP kummandla wokulayisha kwaye sizibeke kwifolokhwe ngokuthe ngqo. Abasebenzisi abakhululekileyo bafumana i-100 MB kwifayili nganye; iPremium ayinalo icebo kwifayili nganye kwaye iqhuba abasebenzi abathe ngqo, ngoko ke umfanekiso we-200-iqela ligqiba ngaphantsi kwemizuzu emibini.

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

Uguqulelo lwefomati ethe ngqo siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imijelo yomhleli we desktop osebenzisa, ngemveliso efanayo yobunjani. Utshintsho luhamba ngaphaya kolawulo lweqela - iinkqubo ze desktop zivula ifayile enye ngexesha; siyamkela iqela.

Uphi ubungakanani obuzakubakho kwifayili yam BMP?

Okumiselweyo ku 1:1 — BMP wakho ugcina ubungakanani be-pixels yomthombo WebP. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva kokuguqula, okanye uyibeke kwi- /image-resize/ utility.

Ingaba i BMP incinane kangakanani na ukuba ingabonakali i-artifacts?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana BMP 60-80% omncinane kune-WebP ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-lossless BMP (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono.

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.
