BMP ukuba WebP Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayile yakho BMP kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye WebP. Ukungabikho kolahleko WebP (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko WebP (JPG, WebP) ungalungisa umgangatho womsebenzi phambi kokukhuphela. I-BMP igcina imiqolo ye-pixel engacinezelwanga ngokupheleleyo enesihloko esincinci, oko kukuthi, yintoni eyenza kube lula ukuchaza ngeenkcukacha. I-WebP inikezela zombini iimeko ezilahlekileyo nezingalahlekileyo, ngokubonisa ngokucacileyo kwe-alpha noopopayi abafumanekayo kumnye.

Ndingafumana ukubonakala okucacileyo xa umfanekiso u WebP?

Ifomati WebP ixhasa oku, kodwa uguqulelo alukwazi ukulivelisa. A BMP ayinasiqhagamshelanisi se-alpha, ngoko ke yonke i-pixel equka indawo yangasemva ifika icacile ngokupheleleyo. Phumeza /susa indawo yangasemva/ emva koko ukucima isiqalo — ngoko i-alpha isiqhagamshelanisi WebP ibonelela ngento yokugcinwa. I-WebP ihlala i-25-35% incinane kune-JPG elinganayo kwaye incinci kune-GIF ephilayo, enesixhaso se-browser esipheleleyo ukusukela ngo-2020.

Ingaba ndiya kulahlekelwa yintoni ngomgangatho xa ndisuka kwi BMP ukuya kwi WebP?

Kwi umgangatho 80- 85 utshintsho alubonakali kumgama wokubona oqhelekileyo kwaye ifayile ihlala iphantsi nge 60- 80%. Ukubamba kukuba yindlela enye: ukubuyisela ukugcina i WebP ngokuphindaphinda idibanisa i artefacts ixesha ngalinye. Gcina i BMP njenge master kwaye uphinde uphinde uvule i WebP ukusuka kuyo xa ufuna ubungakanani obutsha. I-BMP ayifuni i-decoder library, ngoko ihlala ikhuselekile kwifomati yotshintshiselwano lweenkqubo ezifakelweyo kunye nezixhobo zeWindows ezihlala zikhona.

Ingaba uguqulelo BMP ukuya WebP lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa WebP 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 WebP endaweni ye-WebP=JPG. I-WebP yifomati yomfanekiso yeGoogle ka-2010, eyenziwe kwi-VP8 keyframe encoder kwaye imiselwe ukubuyisela i-JPG, i-PNG ne-GIF ngaxeshanye.

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

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi BMP kwaye zidityaniswe kwakhona kwi-WebP 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 BMP ukuya WebP?

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

Ndingaguqula iifayili ezininzi BMP zibe WebP ngaxeshanye?

Ewe - tsala iifayile ezininzi BMP 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-BMP ithelekiswa njani ne-WebP 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 WebP?

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

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

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

Ingaba iifayile zam BMP zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayili ezilayishwe phezulu BMP ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe ngaphakathi kwemizuzu. Asiyi kufunda, sigcine ixesha elide, okanye sinikezele i-pixel data. Ifestile yokugcina epheleleyo ibhalwe kwi /privacy/.

Ingaba i-BMP ukuya kwi-WebP iguqulela isebenza kwimifanekiso emikhulu kakhulu (50MP+)?

Ewe, simahla ukuya kwi-100 MB. I-Premium iphatha izingeniso ezinkulu (300 MB+) kunye nobunzulu obungenakulinganiswa kwi-pixel nganye (16-bit PNG, 32-bit float TIFF). I-pipeline ijikelezisa imiqolo ukuze ukusetyenziswa kovimba weefayili kulinganiswe ngobalo lomqolo, hayi ubalo lwee-pixels ezipheleleyo.

BMP

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