Guqula TIFF ukuba BMP

BMP ayixhasi ukuboniswa ngokucacileyo. Iindawo eziboniswa ngokucacileyo kwi-TIFF ziya kutywinwa phantsi kokungasemva okuqinileyo - omnyama ngokumiselweyo. Ukuba ufuna ukugcina ukuboniswa ngokucacileyo, guqula kwi-PNG, WebP, okanye TIFF endaweni yoko.

Ungaguqula i-BMP kwakhona kwi-TIFF kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Izicwangciso ezimiselweyo zijolise kwi-broadcast / umgangatho we-web - ngokubonakalayo ifana nomcebo kubabukeli abaninzi. Ukusetyenziswa kovimba, khetha ukhetho oluphezulu lomgangatho kwimimiselo yoguquli.

Ziqhotyoshelweyo, ngokusisigxina, kumfanekiso omnye odityanisiweyo. Iinkqubo zokudibanisa, iziqhoboshi, amanqanaba olungiso kunye nombhalo ohlelayo zonke zigqibezela kwipixels yokugqibela kuba BMP ayinaso isakhiwo sokuba zigcine. Gcina i TIFF njengemlawuli osebenza kakuhle kwaye uthathe i BMP ngokungqongqo njenge-export. I-TIFF iphatha i CMYK, ubunzulu be-16-bit, i-ICC efakwe ngaphakathi kunye namaxwebhu ephepha elininzi, eli linyaniso le shicilelo kunye nomsebenzi wokuhamba kovimba ofunayo. I-BMP inamandla amakhulu — umfanekiso we-12-megapixel ujikeleze i-36 MB — kwaye akukho mkhangeli zincwadi uyamphatha njengefomati yewebhu esebenzayo.

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.

Iguqulwe kwi sRGB, kuba BMP ayinayo i CMYK indlela. Ukusetyenziswa kwesikrini oku kulungile. Ushicilelo lweshishini akusebenzi - utshintsho lwegama lokutshintsha indlela imibala ethambileyo ephindayo kwiqhosha, ngoko thumela umshicileli okuqala TIFF endaweni ye BMP.

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-TIFF yifomati yefayili yomfanekiso ophawulwe ukusukela ngo-1986, kwaye yifomati yokukhangela, yoshicilelo kunye nokugcina iinjineli ezimiselwe.

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. I-TIFF yindawo yokugcina engaphezulu kwe-codec: inokuphatha i-data engacinezelwanga, i-LZW, i-ZIP okanye nakwi-JPEG, ukuya kuthi ga kwi-32 bits kwisiqhagamshelanisi ngasinye, ngeephepha ezininzi kwifayili enye. I-BMP igcina imiqolo ye-pixel engacinezelwanga ngokupheleleyo enesihloko esincinci, oko kukuthi, yintoni eyenza kube lula ukuchaza ngeenkcukacha.

Ulayisho phezulu olungaziwayo luphelelwe lixesha ngokumiselweyo; i-akhawunti ebhalisiweyo ekhululekileyo ifumana umda ophezulu, kwaye i-akhawunti ye-Pro ayinalo umda wefayili nganye. Inkumbulo yesikhangeli sihlala siyimfuneko yothintelo ixesha elide phambi kokuba umda wethu we-server-side uqale.

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze TIFF kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze BMP. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.

Iifayili ezilayishwe phezulu kunye ne-BMP iimveliso zicinywa ngokuzenzekelayo emva kwefestile efutshane yokugcina. Asiyi kujonga, sizonwabele, okanye siqeqeshe kwiifayili zomsebenzisi. Ikhonkco lokulayisha ezantsi ngokuthe ngqo limiselwe ixesha kwaye lidityaniswe kwintlanganiso yakho.
