Itai Kuti Mifananidzo Yenyu Ive Yakakura Nokurasikirwa Kwishoma Muhutano
Imwe yemibvunzo inowanzobvunzwa maererano nehuwandu hwemapuraneti ndeyekuti ungawedzera sei ukuru hwechifananidzo kunze kwekuti uwane blurring uye yakagadzirisa mitsetse. Vashandisi vatsva vanowanzoshamiswa pavanenge vachigarisa mufananidzo uye vanoona kuti hutano hwakanyanyisa. Vashandisi vane ruzivo vose vanozivawo dambudziko racho. Chikonzero chekunyadzisa ndekwokuti kukonzerwa , kana raster, mifananidzo yezvifananidzo inogadziriswa nekugadzirisa kwepikisiki yavo. Paunenge uchiedza kugadzirisa marudzi aya emifananidzo, software yako inofanira kuwedzera ukuru hwepikisi imwe neimwe - inogadzira mufananidzo wakajeka - kana kuti "kufungidzira" nenzira yakanakisisa yekuwedzera pixels kumufananidzo kuti uite .
Pasina nguva refu, kwakanga kusina zvakawanda zvingasarudzwa zvekuwedzera kusarudzwa kunze kwekushandisa yako kugadzirisa software yakagadzirwa-mukutsvaga nzira. Nhasi, tatarisana nemikana yakawanda kudarika kare. Zvechokwadi, nguva dzose zvinonakidza kutora sarudzo yaunoda kubva pakutanga. Kana iwe uine sarudzo yekutsvaga mufananidzo pane imwe sarudzo yakakwirira, nenzira dzose, iwe unofanira kuzviita usati watanga mapurogiramu e-software. Uye kana iwe uine mari yekuisa mukhamera inokwanisa kugadziriswa, iwe ungawana kuti mari inoshandiswa zviri nani kudarika kana iwe uchizoiisa mune imwe shanduro yekugadzira software. Kana uchitaura izvozvo, pane nguva dzakawanda apo iwe ungave usina imwe sarudzo kunze kwekushandisa kune software. Apo nguva iyoyo inouya, heinoi mashoko aunofanira kuziva.
Kudzorera vs. Kusarudzwa
Mazhinji software ine mutemo mumwechete wekuti zvose zvigadziriswe uye zvigadziriswe. Kuderedza mufananidzo kunosanganisira kuchinja mapepa ekudhinda pasina kushandura zviyero zvepikisi. Sezvo chisarudzo ichiwedzerwa, huwandu hwapamusoro hunove hudiki, uye pamwe chete. Paunowedzera chisarudzo usingashandisi pixel miviri, hapana kurasikirwa muhutano, asi iwe unofanirwa kupira ushizha hwekudhinda. Kudzokorora mufananidzo uchishandura tsvakurudzo, zvisinei, kunosanganisira kuchinja mapikisi ekuyera uye nguva dzose inotanga kurasikirwa muhutano. Ndiko kushandiswa kwekushandisa kunoshandisa chirongwa chinonzi interpolation pakuwedzera ukuru hwemufananidzo. Nzira yekushandura inofungidzira maitiro emapikiseli iyo software inofanira kusika zvichienderana nemapikiseli akange aripo mumufananidzo. Kudzokorora kuburikidza nemigumisiro yezvinyorwa mukumhanya kwakanyanyisa kwemufananidzo wakagadziriswa, kunyanya munzvimbo dzave nemiganhu yakakosha uye kuchinja kwakasiyana kwemuvara.
• Pamusoro peKushamba Kwemifananidzo & Kugadziriswa
Chimwe chinhu chekukonzera uku ndiko kukwira kwe smartphone uye tablet uye zvakatarisana zvakananga pane pixel yedhijisiti. . Aya majaira ane pixel maviri kana matatu munzvimbo imwechete inotorwa nepixel imwe pakombiyuta yako. Kufamba chifananidzo kubva kombiyuta yako kuenda kune imwe kambani kunoda iwe kuti uite mazana evhidhiyo yemufananidzo wakafanana (p. 1X, 2X uye 3X) kuti uone kuti vanoratidzira zvakanaka pane imwe kifaa. Izvo zvinowedzera hukuru hwechifananidzo kana kuwedzera nhamba yemapikseli.
Nzira Dzakasiyana-siyana dzekushandurudza
Mufananidzo wekugadzira software inowanzopa nzira shoma dzakasiyana-siyana dzekunyorwa kwekuverenga mapikisikisi matsva apo chifananidzo chatinopindurwa. Pano pane tsanangudzo dzemhando nhatu dzinowanikwa mu Photoshop.

- Bicubic ndiyo inononoka asi inounza kuongororwa kwakanakisisa kwepikisi itsva maonero.
- Bilinear inokurumidza kupfuura bicubic, asi inoita basa rakashata. Zvose bicubic uye bilinear interpolation zvinoguma nemufananidzo wakajeka, kunyanya kana upsampling.
- Muvakidzani ari pedyo haashandisi interpolation. Inongotora kukosha kwepikisera yepedyo uye inowedzera mapikiseti matsva pasina kuvanza. Iyi ndiyo apo iwe unowana jaggies kana stair-step effect.
Cherechedza kuti kune zvimwe zvinopfuura izvi zvitatu nzira yekushandura uye kunyange kushandisa nzira imwechete mumapurogiramu akasiyana-siyana inogona kubudisa mhinduro dzakasiyana. Muzviitiko zvangu, ndakaona kuti Photoshop inopa yakanakisisa bicubic interpolation yeimwe sangano randakafananidza.
