Momwe Mungayankhire Kusinthidwa kwa Zithunzi Zosindikizira
Pano pali funso ndi yankho kuchokera ku vuto lenileni la wowerenga lomwe likukhudzana ndi kuthetsa chifaniziro. Izi ndizokongola kwambiri zomwe anthu ambiri akuyenera kuthana nazo pamene akufunsidwa kuti fano yogwiritsidwe ntchito pofalitsa ...
"Munthu wina akufuna kugula chithunzi kuchokera kwa ine. Amafunika kuti ikhale 300 DPI, 5,58 mainchesi Chithunzi chomwe ndili nacho ndi 702K, 1538 x 2048 Jpeg Ndimawona kuti ziyenera kukhala zazikulu zokwanira! Ndondomeko ya chithunzi chokha chomwe ndili nacho ndi Paint.NET, ndipo sindikutsimikiza zomwe ndikufuna kudziwa. Ngati sindikusokoneza, zimandiuza kuti chiganizo changa ndi ma pixel 180 / inch, kukula kwake pafupifupi 8 x 11. Ngati ndipanga ma pixelisi 300 / inchi (ndi chimodzimodzi ndi DPI?) Ndikhoza kupeza kukula kwa kusindikiza komwe kumagwira ntchito, pafupifupi 5 x 8, ndipo kumasintha kukula kwa pixel kufika 1686 x 2248. Ine ndikuyenera kuti ndizichita ??? Izo sizikuwoneka ngati kusintha kwakukulu kwa diso la umunthu. "
Zambiri zachisokonezo ichi ndi chifukwa chakuti anthu ambiri samagwiritsa ntchito mawu omveka bwino. Amati DPI akakhala akunena PPI (pixels per inch). Chithunzi chanu ndi 1538 x 2048 ndipo mukusowa kukula kwa masentimita 5x8 ... masamu omwe mukufunikira ndi:
mapilosi / inchi = PPI
1538/5 = 307
2048/8 = 256
Izi zikutanthauza kuti 256 ndipamwamba kwambiri PPI yomwe mungapeze kuchokera ku chithunzi ichi kuti musindikize mbali yayitali kuposa masentimita asanu popanda kulola mapulogalamu anu kuwonjezera pixels atsopano. Pamene pulogalamu yanu iyenera kuwonjezera kapena kuchotsa ma pixel, imatchedwa kuyambanso , ndipo imabweretsa kuwonongeka kwa khalidwe. Kusintha kwakukulu kwambiri, kumveka bwino kuti imfa yapamwamba idzakhala. Mu chitsanzo chanu, sizinthu zambiri, kotero kutayika sikudzaonekeratu ... monga momwe mwaonera. Pankhani ya kusintha kwakung'ono, ndimakonda kusindikiza chithunzi cha PPI chapansi. Nthawi zambiri zimapanga zabwino . Koma popeza mutumiza izi kwa munthu wina, mumangoyenera kulandira zitsanzo kuti muzipanga 300 PPI.
• Zambiri pa Kutsitsa
Zomwe munachita pa Paint.NET ndi zabwino malinga ngati mukudziwa ndikumvetsa kuti pulogalamuyo imakhala chitsanzo cha fano. Nthawi iliyonse miyeso ya pixel imasinthidwa, izi ndizomwe zimapangidwira. Pali njira zambiri zothandizira kukonzanso, ndipo mapulogalamu osiyanasiyana amagwiritsa ntchito njira zosiyanasiyana. Mapulogalamu ena amakupatseni mwayi wosankha njira zosiyanasiyana. Njira zina zimagwira ntchito pochepetsera kukula kwajambula (zowonongeka) ndipo ena amagwira ntchito bwino pakuwonjezera kukula kwa fano (upsampling) monga mukufuna kuchita. "Quality Quality" mu Paint.NET ayenera kukhala zabwino zomwe muyenera kuchita.
• Zambiri pa Njira Zopangidwira
Kusintha kwanga kuchita masewero olimbitsa thupi kungakuthandizeni kukumbukira zonsezi. Zalembedwa ngati gawo langa la Photoshop CS2, koma bokosi loti likhale logwiritsa ntchito mapulogalamu ena lingakhale lofanana kuti mutha kutsatira.
• Kupititsa patsogolo Kuchita Zochita
Onaninso: Ndingasinthe bwanji kukula kwa chithunzi cha digito?
Vuto lina lomwe muli nalo ndilo kuti miyeso yanu ndi yosiyana yofanana ndi kukula kwa kusindikiza komwe kwapempha. Izi zikutanthauza kuti mukuyenera kujambula chithunzicho ngati mukufuna kulamulira pa zomwe zikuwonetsedwera kutsiriza.
• Kuwoneka kwa maonekedwe ndi kudula ku Miyeso Yoyenera
Pano pali kufotokozera kwina kwowonjezera:
"Pamene ndimayesa kupanga chithunzichi kukhala PPI wapamwamba, ndinkayembekezera kuti ma pixel nambala zichepe kusiyana ndi kuwonjezeka. Ndikuganiza kuti ndimaganiza kuti ngati palibe pixelisi yokwanira kuti ndifike kukula komwe ndikukufuna pamapeto omwe ndikufuna, kuwatulutsa 'mwinamwake, osandipatsa zambiri. Tsopano popeza ndawerenga ndondomeko yanu, ndikudziwa chifukwa chake pali pixelsi zambiri, osachepera. "
Zimene munanena ponena za kufalitsa ma pixelisi ndizochitika makamaka pamene mutumiza fayilo yosinthira pansi pa printer. Paziganizo zochepa, ma pixel amayamba kufalikira ndipo mumataya tsatanetsatane; pa mapikseli apamwamba kwambiri amasungunuka pamodzi, kupanga zambiri. Kupangidwanso kumayambitsa mapulogalamu anu kupanga mapikisilosi atsopanowo, koma kungangopanga zoganiza zenizeni - sizingapangitse tsatanetsatane kusiyana ndi zomwe zinalipo poyamba.
