Funda indlela i-Pixel Size kunye nePolitiki ngayo
Xa ukwandisa ubukhulu bomfanekiso wedijithali, enye indlela yokudibanisa eyenzekayo kwaye inokuchaphazela kakhulu umgangatho wefoto. Kubalulekile ukuba abathwebuli beefoto baqonde ukuba yiyiphi intetho kunye nendlela yokuphucula iziphumo zayo.
Yintoni i-Interpolation?
I-polpolation yithuba elisetyenziswe ukuchaza indlela yokwandisa ubukhulu beepikseli ngaphakathi komfanekiso . Ngokuqhelekileyo kusetyenziselwa ukwandisa ubukhulu bomfanekiso.
Ukwandisa ubungakanani bomfanekiso ngokuqhelekileyo akukwaziswa ngokuba ikhompyutha idinga ukusebenzisa intsebenziswano yokongeza ulwazi olungengowokuqala. Imiphumo yale nto ingahluka ngokusetyenzwa kwindlela yokusetyenziswa kwamagama kodwa, ngokuqhelekileyo, akulungile.
Njengoko ikhomputha izama ukutshilwa yintoni ulwazi olutsha kufuneka longezwe, umfanekiso ungabonakala okanye ube neenkalo ezincinci zombala okanye ithoni ebonakala ingekho ndawo.
Ezinye iikhamera zedijithali (iindawo ezininzi kunye nokudubula iikhamera kunye neefowuni) sebenzisa ukudibanisa ukudala i- 'zoom zoom '. Oku kuthetha ukuba ikhamera inokusondeza ngaphaya kobubanzi obukhulu obuvunyelwe yilenki yekhamera (ebizwa ngokuba yi-zoom zoom). Ukuba usebenzisa enye yeekhamera, ngokuqhelekileyo kukulungele ukuba usondele ngakumbi kwisifundo kunokuba usebenzisa i-zoom zoom.
I-interpolation isetyenziswe rhoqo kwi-software yekhamera ye-imaging kwaye yilapho i-photographer ifuna ukuqonda iintlobo ezahlukeneyo zokudibanisa.
Ulwalamano olusondeleyo lwabahlali
Ukudibanisa ummelwane oqhelekileyo kudla ngokusetyenziswa kwi-khamera xa uhlaziya kwaye ukwandisa imifanekiso ukujonga iinkcukacha. Yenza ukuba iipixelli zikhudlwana, kwaye umbala wepikelli entsha ufana nepiksile yangaphambili.
Ukungalungi: Akufanelekanga ukukhulisa imifanekiso yokuprinta njengoko ingavelisa i-jaggies .
Billyar Interpolation
I-Bilinear interpolation ithatha ulwazi kwi-pixel yasekuqaleni, kunye nee-pixel ezine ezithintelayo, ukugqiba umbala wepikelli entsha. Ivelisa iziphumo ezintle, kodwa iyanciphisa umgangatho kakhulu.
Ukungalungi: Izithombe zingaba zibukhali.
Bicubic Interpolation
I-bicubic interpolation yinkqonkqo kakhulu yoluhlu, njengoko ithatha ulwazi kwi-pixel yangaphambili kunye neepikseli ezili-16 ezijikelezayo ukudala umbala wepikelli entsha.
Ubalo bicubic luphambili kakhulu kunezinye iindlela ezimbini, kwaye liyakwazi ukuvelisa imifanekiso ephezulu yokuprinta. I-bicubic interpolation inikezela ngezimilo ezimbini ze "Smoother" kunye ne "Sharper" kwiziphumo ezicwangcisiweyo.
Ukungalungi: Nangona enye yeyona ndlela enokukhetha, enkulu kakhulu yokungena kwisayizi inokunciphisa izinga lomfanekiso.
I-Interpolation yeFractal
Eyona nto isetyenziselwa iimpapasho ezinkulu, ama-sampuli angamaqhinga okubhaliweyo ukusuka kumaphikiseli angaphezu kwe-bicubic interpolation. Ivelisa imiphetho ebanzi kwaye idibanisa ngaphantsi kodwa idinga isofthiwe ecacileyo kakhulu ukuyisebenzisa. Abashicileli bezakhono bahlala besetyenziselwa ukudibanisa.
Iingxaki: Uninzi lwesofthiwe yekhompyutha ayinalo olu khetho.
