BMP Uguqulelo lwe FAQ

Yintoni ifayili BMP?

I-BMP (Ifayile yomfanekiso we-Bitmap) ibhekisa kwifomati ye-raster graphic esetyenziswa ukugcinwa kwemifanekiso ye-bitmap yedijithali.

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 imifanekiso yekhusi iphuma njenge BMP?

Kuba iscreenshot ngumfanekiso omnye ohlobo olulo olufomati lungcono kakhulu. Oku kukwikhusi kumbala othambileyo, umbhalo kunye namazantsi aqinileyo - ngokuchanekileyo imixholo yoxinzelelo olungalahliyo iphatha kakuhle kwaye ikhowudi yomfanekiso ikhutshwa - kwaye inkqubo yokusebenza iyazi, ngoko ayikuboneleli ngenketho. Ukutshintsha iscreenshot kwifomati yomfanekiso ngokuqhelekileyo yenza kube mkhulu kwaye ophuculekileyo. I-BMP ayifuni i-decoder library, ngoko ihlala ikhuselekile kwifomati yotshintshiselwano lweenkqubo ezifakelweyo kunye nezixhobo zeWindows ezihlala zikhona.

Kutheni le nto i BMP yam ikhulu kakhulu kunefoto efanayo njenge-JPG?

Kuba igcina ipixel nganye, kwaye kwifoto akukho ifoto ezimbini ezifanayo. Uxinzelelo olungalahliyo lusebenza ngokufumanisa ukuphindaphinda, kwaye ingqolowa, intshukumo kunye nethambeka linika okuncinci kakhulu, ngoko ifayile ihlala ifutshane nobungakanani bayo obungenakugqitywa. Kwiscreenshot, ilogo okanye umzobo womgca uxinzelelo olufanayo luhle. Olu hlobo - oluhle kumbala othambileyo, olulahlayo kwimifanekiso - luyinto yonke yembali yexesha apho le fomati ilungile. I-BMP inamandla amakhulu — umfanekiso we-12-megapixel ujikeleze i-36 MB — kwaye akukho mkhangeli zincwadi uyamphatha njengefomati yewebhu esebenzayo.

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.

Ingaba i-BMP yifomati efanelekileyo yemifanekiso engumbhalo nemifanekiso engumzobo?

Ewe, ngenxa yesizathu esicacileyo esiyingxaki elungileyo yemifanekiso. Ujongano lwe chrome, umbhalo kunye nemifanekiso eqingqiweyo eqinileyo yezona ndawo zikhulu zombala ofanayo kunye nemida eqaqambileyo, eyenza uxinzelelo olungalahliyo lusebenze kakuhle kwaye uxinzelelo olulahlayo lugweme - ukubonisa kukukhanya okumnyama okuvela phezulu koonobumba xa umfanekiso wekhusi udlula kwikhowudi yomfanekiso. Gcina imifanekiso yekhusi apha kwaye uyiguqule kuphela xa into ephantsi kwendlela i insists.

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. I-BMP yi-Windows Bitmap, ifomati ye-raster egqityiweyo eyenziwe kwi-Windows ukusukela ngo-1985.

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 solawulo 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.

Ndingayinika kwakhona igama elipheleleyo lesiqendu endaweni yokuguqula i BMP?

Akukho nanye, kwaye ifanele ukuqonda kutheni: unikezelo luphawu, ngelixa i bytes ngaphakathi zidityaniswe kwifomati ekhethekileyo. Ukuphinda ubize ifayile ivelisa ifayile igama layo lithembisa into imixholo yayo ayinikezeli, kwaye nantoni na evula ifayile okanye ilahlekile ifayile okanye ifunda ngokungachanekanga. Ukuphela kwendlela efutshane kuhlobo olubini oluyinyani ibhokisi efanayo phantsi kwegama elahlukileyo - kwaye nalapho ukuphinda ubhale ngokuchanekileyo kukhuselekile kunegama elahlukileyo.

Ndingaguqula isiqulathi seefayili esipheleleyo se BMP iifayili ngenye indlela?

Nge akhawunti, ewe - shiya ngaphaya kunye kwaye zifolwa njengemisebenzi enye endaweni yokuphathwa enye ngexesha, ngemimiselo efanayo esetyenziswa kwiqela kunye neziphumo ezibuyiselweyo kunye. Uguqulelo oluzenzekelayo luqhuba ifayile enye ngexesha (izixhobo zokudibanisa zithatha ezimbini); inkqubo ehlawulweyo ivula uqhubekeko lweqela kunye nobukhulu befayile nganye umda, owenza uguqulelo lwefayile yonke yovimba isebenziseke.
