GIF ukuba BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili yakho ye GIF 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-GIF ayilahleki kodwa iphele kwi-256-imibala yengqokelela yezixhobo ngesakhelo ngasinye, isebenzisa uxinzelelo lwe-LZW kunye nokukhanya okubini kombala omnye. I-BMP igcina imiqolo ye-pixel engacinezelwanga ngokupheleleyo enesihloko esincinci, oko kukuthi, yintoni eyenza kube lula ukuchaza ngeenkcukacha.

Ingaba ukubonakaliswa okubonakalayo kuya kuqhubeka nokutshintsha GIF 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.

I GIF 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 kukho into elahlekile ekuguquleni phakathi kwe GIF ne BMP?

Akukho data yepixel, hayi. Zonke iifomati zigcina umfanekiso ngaphandle koxinzelelo olulahlekileyo, ngoko ke umfanekiso ophumayo ufana nowo waya ngaphakathi kwaye uguqulelo luyaphinda uphinde luphinde. Okutshintshayo kubungakanani befayili, kwaye oku kusebenza ukuhamba - ubunzulu bombala, iiprofayili ezifakelweyo, amanqanaba noopopayi bonke baxhaswa ngokungalinganiyo phakathi kwefomati ezingalahlekileyo.

Ingaba uguqulelo GIF 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 GIF ukuya ku BMP?

Iiprofayili zombala we-ICC ezifakelweyo zifundwa kumvelaphi GIF 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 GIF ibe yi BMP?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS) igcinwa ngokumiselweyo ngexesha GIF -> 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 GIF zibe BMP ngaxeshanye?

Ewe - rhuqa iifayile ezininzi GIF 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-GIF 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-GIF. 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-GIF 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. I-BMP ayifuni i-decoder library, ngoko ihlala ikhuselekile kwifomati yotshintshiselwano lweenkqubo ezifakelweyo kunye nezixhobo zeWindows ezihlala zikhona.

Ingaba iifayile zam GIF zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu GIF ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asizukufunda, sigcine, okanye sisebenzise i-pixel data. Ifestile yokugcina epheleleyo ibhalwe kwi /privacy/.
