Malunga BMP

Iifayili ze-BMP zigcina imifanekiso kwifomati ye-bitmap engacinezelwanga, ebangela ubungakanani befayili bube bukhulu kodwa bube bulungele isiqhelo.

BMP Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni i-BMP?

I-BMP yifomati yomfanekiso we-raster engenakulahleka egcina yonke i-pixel ngaphandle koxinzelelo lwezinto ezibonakalayo. I-BMP ilungele kakhulu imifanekiso eqingqiweyo yekhusi, umzobo womgca, imifanekiso engumzobo enemiphetho eqinileyo nanoma yiphi na imifanekiso elandelayo eza kugcinwa. I-BMP ayifuni i-decoder library, ngoko ihlala ikhuselekile kwifomati yotshintshiselwano lweenkqubo ezifakelweyo kunye nezixhobo zeWindows ezihlala zikhona.

Ingaba kukho into elahlekile xa i BMP iguqulwa ibe yifomati enye engalahlekiyo?

Akukho data ye-pixel. BMP igcina umfanekiso ngokuchanekileyo kunokuba ilinganise, ngoko uguqulelo phakathi kwefomati ezimbini ezingalahlekiyo luyabuyiselwa kwaye luyaphinda kungekho xesha lide ngaphandle kokulahleka. Okunokuphelelwa yinto yonke ejikeleze ii-pixels - iiprofayili zombala, ukuqaqamba, udweliso, i-metadata efakwe ngaphakathi - kuba inkxaso yazo itshintsha kakhulu phakathi kwefomati kunendawo yokugcina i-pixel. I-BMP igcina imiqolo ye-pixel engacinezelwanga ngokupheleleyo enesihloko esincinci, oko kukuthi, yintoni eyenza kube lula ukuchaza ngeenkcukacha.

Kutheni i-screen recorder yam igcina i-BMP?

Kuba yifomati ekhowudiweyo yenkqubo yoshicilelo, ngoko ukuqokelelwa kubiza ngaphezu kokungasebenzisi uqhubekeko- magama ngelixa isixhobo sixakekile sisenza enye into. Kukhetho olunolwazi ngelixa kushicilelo kwaye kunzima emva koko - ifayile ifuna ukuguqulwa phambi kokuba ikwazi ukunikezelwa, ukuhlela okanye ukufakelwa naphi na ngaphandle kwendlela eyenzayo. I-BMP yi-Windows Bitmap, ifomati ye-raster egqityiweyo eyenziwe kwi-Windows ukusukela ngo-1985.

Kutheni le nto isiqalo sam esicacileyo sitshintshe simhlophe kwi BMP?

Kuba BMP ayinasiqhagamshelanisi se-alpha sokugcina kuyo. I-pixel nganye kufuneka ibe nombala oqinileyo, ngoko ukubonakala okucacileyo kudityaniswa nokungasemva - omnyama ngokumiselweyo - kwixesha apho ifayili ibhalwa khona. Akukho nto ibuyiselwa emva koko. Ukuba umfanekiso ufuna ukuba uhlale kwiphepha elimnyama okanye ngaphezulu komfanekiso, guqula kwifomati egcina ukubonakala okucacileyo endaweni yoko. I-BMP inamandla amakhulu — umfanekiso we-12-megapixel ujikeleze i-36 MB — kwaye akukho mkhangeli zincwadi uyamphatha njengefomati yewebhu esebenzayo.

Ingaba ndimele ndigcine iifayile ezintsha njenge BMP?

Ukuba into ephantsi kwendlela ifuna oku. Ifomati iyaqhubeka ivula, kwaye akukho mcimbi wokuguqula uvimba ongazibangela iingxaki, kodwa ayikwazi ukuqhubeka apho isixhobo okanye usebenziso luya khona. Kwanoma iyiphi into entsha, ifomati yangoku ayihlawuli nto engaphezulu kwaye ikhusela umjikelo olandelayo wombuzo kwiminyaka emininzi ezayo.

Ingaba kubaluleke na ukuba u BMP uneminyaka engaphezu kweeminyaka ezimashumi amathathu ubudala?

Ubudala ngokwalo alukuyingxaki - iifomati ezininzi ezivela kulo nyaka zihlala zilungile, ngokucacileyo ngenxa yokuba konke kwakuba neminyaka emininzi yokuzisebenzisa. Okubalulekileyo kulapho ixesha licinga khona: iifayile ezincinci, abaqhubi abancinci, akukho msebenzi womnatha, kunye neempawu ezingafunekiyo. apho ezi zinto zicinga khona, ifomati ilungile. apho azisebenzi, le yisizathu sokuguqula.

Ingaba BMP yifomati yeMicrosoft endifunayo isoftware yeMicrosoft?

Ivela kwi Microsoft, kwaye apho uxhulumaniso luphela khona. Akukho sicelo esiqalayo esilahlekileyo kwaye akukho layisensi yokuyigcina: ubeko lwapapashwa, lumalunga nolula njengefomati yefayile ifumana, kwaye yonke indlela yokusebenza nesixhobo sesixhobo sifunde kwaye sibhale iminyaka emininzi. Oku uguqula kuyo kubungakanani kunye nomsebenzi, musa ukufikelela.

Kutheni le nto i-BMP ayibonisi kwi-browser yam?

Kuba iiseva zisebenzisa uluhlu olufutshane lweefomati zomfanekiso kwaye BMP ingaphandle kwayo - ibhekisa kuvavanyo, ushicilelo okanye uqhubekeko-msebenzi lweenkqubo eziguqula inkqubo yekhompyutha kunokuba ikwi-web. Ifayile ayilahleki; ayinakho ukucofa ikhowudi kwiphepha. Ukutshintsha kwifomati yomfanekiso we-web-esemthethweni kugqibo lwenyathelo elinye kwaye ngokuqhelekileyo yenza ifayile ibe ncinci kakhulu.

Ndimele ndiguqule njani i-BMP ibe yifomati enye?

Guqula i-BMP ibe yi-JPG okanye i-WebP xa umxholo omiselweyo uvula i-web okanye i-imeyile, apho ubungakanani befayili obuncinci bubalulekile ngakumbi kune-pixel nganye.

Ingaba ukujika i-BMP kuya kunyusa ubunjani bomfanekiso?

Xa uguqula i-BMP ibe yifomati engalahlekiyo, ii-pixels zigcinwa ngokuchanekileyo. Xa uguqula i-BMP ibe yifomati engalahlekiyo njenge-JPG, i-encoder isenza umgangatho-vs-ubungakanani be-trade-offs olawula ngazo nge-output quality setting.
