Guqula TIFF ukuba PNG

Ewe. Zonke i-TIFF ne-PNG zixhasa isiqhagamshelanisi se-alpha, ngoko imimandla ebonisa ngaphaya neyokubonisa ngaphaya kwecala ihamba ngaphandle kotshintsho.

Ungaguqula i-PNG 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 PNG ayinaso isakhiwo sokuba zigcine. Gcina i TIFF njengemlawuli osebenza kakuhle kwaye uthathe i PNG 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-PNG yifomati yomfanekiso ophantsi: umfanekiso ogciniweyo njenge-PNG uhlala ukhulu ngee-5 ukuya kwi-10 amaxesha kunemifanekiso efanayo njenge-JPG okanye i-WebP.

Iguqulwe kwi sRGB, kuba PNG 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 PNG.

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-PNG isebenzisa uxinzelelo lwe-DEFLATE ngaphezulu kwamagqabantshintshi okuskena acociweyo, ngoko ke i-pixel nganye ihlala ngokuchanekileyo, kunye ne-8-bit epheleleyo ye-alpha channel.

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 PNG. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.

Iifayili ezilayishwe phezulu kunye ne-PNG 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.

PNG ivuliwe ngokusemthethweni kwi-browser nganye yakudala, kwi-viewer nganye yomfanekiso, kunye ne-app nganye yokulungisa iifoto. Akukho nkqubo efunekayo.
