Yintoni isiGqibo soMfanekiso?
La Isisombululo somfanekiso ibhekisa kubungakanani benkcukacha onokuqulatha umfanekiso wedijithali. Ilinganiswa nge 'iipixels nge-intshi nganye' (PPI) okanye kwi 'amachaphaza nge-intshi nganye' (DPI) kwimeko yemifanekiso eprintiweyo. Umfanekiso wesisombululo esiphezulu uya kuba neepikseli ezininzi, eziguqulela kwiinkcukacha ezininzi kunye nomgangatho womfanekiso ophezulu.
Isisombululo somfanekiso sibaluleke kakhulu xa kuziwa ekushicileleni okanye ekubukeni kwizikrini ezinkulu. Kwezi meko, isisombululo esiphezulu sinokwenza umahluko phakathi komfanekiso obukhali, ocacileyo kunye nomfanekiso owenziwe ngepikselite kunye nongasebenziyo.
Ukuqonda iiPixels
I-pixel, esisifinyezo "sento yomfanekiso", yinxalenye esisiseko yomfanekiso wedijithali. Iphikseli nganye inamacandelo amathathu - obomvu, eluhlaza kunye noluhlaza okwesibhakabhaka - ukuba kunye inokuvelisa nawuphi na umbala ngento ebizwa ngokuba ngumxube wokudibanisa.
- Umfanekiso osezantsi: Ukuba umfanekiso unesisombululo esisezantsi (o.k. pixels ezimbalwa), iinkcukacha zomfanekiso ziyalahleka, okukhokelela kumfanekiso omfiliba okanye owenziwe ngepixelated.
- Umfanekiso ophakamileyo: Umfanekiso onesisombululo esiphezulu (eneepikseli ezininzi) unokubonisa iinkcukacha ezininzi, okukhokelela kumfanekiso ocacileyo, obukhali.
ISigqibo siwuchaphazela njani umgangatho womfanekiso?
Inani leepixels eziqulethwe ngumfanekiso limisela isisombululo sawo kwaye, ke ngoko, umgangatho obonwayo womfanekiso. Xa umfanekiso okwisigqibo esisezantsi wandiswa (umzekelo, oza kuprintwa okanye uboniswe kwiscreen esikhulu), iipixels 'zoluliwe', nto leyo enokukhokelela kwinkangeleko enepixelated okanye eluzizi.
Kubalulekile ukukhumbula ukuba nangona unokunciphisa ubungakanani bomfanekiso ophezulu ngaphandle kokuchaphazela kakubi umgangatho walo, inkqubo yokubuyisela umva ayinakwenzeka. Oko kukuthi, awukwazi ukwandisa isisombululo somfanekiso osezantsi ngaphandle kokuthoba umgangatho womfanekiso.
Isisombululo soMfanekiso kunye neLizwe leDijithali
Kwilizwe ledijithali, ukusonjululwa kwemifanekiso kubalulekile kwiindawo ezahlukeneyo: uyilo lwegraphic, ukufota ngedijithali, kunye newebhu. Kuyilo lwegraphic kunye nokufota kwedijithali, isisombululo esiphezulu sivumela ukuhlelwa kwemifanekiso echanekileyo kunye neenkcukacha.
Ngokwewebhu, isisombululo esaneleyo siqinisekisa umboniso ogqibeleleyo womfanekiso kwizixhobo ezahlukeneyo. Nantsi ingcamango ye "imifanekiso ephendulayo", ebhekiselele kwimifanekiso ehambelana nobukhulu kunye nesisombululo sesixhobo sokubonisa.
Ukulungiselela iMifanekiso yeWebhu
Injongo yokulungiswa komfanekiso wewebhu kukugcina ibhalansi phakathi kwesisombululo esiphezulu somgangatho ophezulu womfanekiso kunye nobukhulu befayile encinci ukuvumela ukulayishwa kwekhasi ngokukhawuleza.
- Ukunciphisa ubungakanani befayile: Izixhobo zokucinezela umfanekiso zinokunceda ukunciphisa ubungakanani befayile ngaphandle kokuthoba umgangatho womfanekiso obonakalayo.
- Uhlengahlengiso lomfanekiso: Ukubuyisela ubungakanani bomfanekiso kubukhulu obuchanekileyo obuya kufuneka kwiwebhusayithi kwakhona kunokunceda ukugcina ubungakanani befayile encinci kunye nexesha lokulayisha ngokukhawuleza.
Ngale ndlela, ukuqonda isisombululo somfanekiso kuluncedo kakhulu zombini ukuqinisekisa amava alungileyo omsebenzisi xa ubrawuza iphepha kunye nokutsala iindwendwe ezininzi ngokubeka umgangatho ongcono kwiinjini zokukhangela.
Ngaloo ndlela, siye sangena kwiingcamango ezisisiseko zokulungiswa kwemifanekiso kwindawo yedijithali, siqwalasela izixhobo kunye nemigaqo eluncedo kunyango kunye nokulungiswa kwemifanekiso yedijithali.
