Indlela Yokubala Isixazululo Sezithombe Zokushicilela
Nansi umbuzo kanye nempendulo evela kunenkinga yomhlaba wangempela we-reader yokubhekana nokulungiswa kwesithombe. Lokhu kuhle kakhulu ukuthi yikuphi abantu abaningi okufanele babhekane nabo lapho becelwa isithombe esisebenzisayo ekushicileleni ...
"Omunye ufuna ukuthenga isithombe kimi. Budinga ukuthi kube ngu-300 DPI, ama-intshi angu-5x8. Isithombe enginakho singama-702K, 1538 x 2048 jpeg. Ngifaka ukuthi kufanele ibe mkhulu ngokwanele! Kodwa ngitshela kanjani? Uhlelo lwesithombe kuphela enginalo i-Paint.NET, futhi angiqiniseki ukuthi ungitshela ukuthi yini engifuna ukuyazi. Uma ngingangcolisi nayo, ingitshela ukuthi isinqumo sami singamaphikseli angu-180 / intshi, ngobukhulu cishe 8 x 11. Uma ngenza amaphikseli angu-300 / intshi (ingabe ifana no-DPI?) ngingathola usayizi wokuphrinta osebenzayo, cishe u-5 x 8, futhi uguqula ububanzi bephikelel kuya ku-1686 x 2248. Yilokho okwenzayo Ngifanele ngiyenze ??? Akubonakali njengokushintsha okukhulu emehlweni esintu. "
Kuningi kwalokhu kudideka ngoba abantu abaningi abasebenzisi igama elifanele. Bathi i- DPI uma kufanele bathi PPI (amaphikseli ngamasentimitha). Isithombe sakho siyi-1538 x 2048 futhi udinga usayizi wokuphrinta wama-intshi angu-5x8 ... izibalo ozidingayo yi:
amaphikseli / intshi = PPI
1538/5 = 307
2048/8 = 256
Lokhu kusho ukuthi 256 yi-PPI esiphezulu ongayithola kulo mfanekiso ukuphrinta uhlangothi olude kunama-intshi angu-8 ngaphandle kokuvumela isofthiwe yakho ingeza amaphikseli amasha. Uma isofthiwe yakho kufanele ingeze noma isuse ama-pixel, ibizwa ngokuthi i- resampling , futhi iholela ekulahlekelweni kwekhwalithi. Ukushintsha okukhulu kakhulu, ngokusobala ukulahlekelwa kwekhwalithi kuyoba. Esikhathini sakho, akusikho okuningi, ngakho ukulahlekelwa ngeke kubonakale kakhulu ... njengoba usubonile. Endabeni yale ncane yenguquko, ngivame ukukhetha ukuphrinta isithombe esincane se-PPI. Ngokuvame ukushintsha kahle . Kodwa njengoba uthumela lokhu kumuntu othile, kuzodingeka ukuthi wamukele ukusampula ukuze wenze i-300 PPI.
• Okuningi ekuPhakamweni
Lokho okwenzile ku-Paint.NET kuhle uma nje wazi futhi uqonde ukuthi isofthiwe izobe isampula isithombe. Noma kunini uma ubukhulu bephikseli buguqulwa, lokhu kuhlaziywa. Kukhona ama-algorithm amaningi ahlukene wokuphenya, futhi isofthiwe ehlukene isebenzisa izindlela ezahlukene. Isofthiwe ethile inikeza ngisho nokukhethwa kwezinhlelo ezihlukile. Ezinye izindlela zisebenza kangcono ekunciphiseni usayizi wesithombe (ukusika phansi) futhi abanye basebenza kangcono ekwandiseni usayizi wesithombe (ukuphakanyiswa) njengokuthanda ukukwenza. "Ikhwalithi engcono kakhulu" ku-Paint.NET kufanele ifanele lokho okudingeka ukwenze.
• Okuningi kuZindlela zokuPhakamisa
Ukuguqulwa kwesenzo sami sokuguqula umzimba kungasiza ukwenza konke lokhu kucace kuwe. Kubhaliwe njengengxenye yenkambo yami ye-Photoshop CS2, kodwa ibhokisi lebhokisi lebhokisi lengxoxo kwenye isofthiwe lingalingana ngokwanele ukuthi ungakwazi ukulandela.
• Ukuvuselela Ukuzivocavoca
Futhi ubone: Ngishintsha kanjani usayizi wokuphrinta wesithombe se-digital?
Enye inkinga onayo ukuthi ubukhulu bakho buyingxenye ehlukile yesici kusuka kusayizi lokuphrinta eliceliwe. Lokhu kusho ukuthi uzodinga ukutshala isithombe sakho uma ufuna ukulawula lokho okuboniswa ekuphrintiweni kokugcina.
• Ukulinganisa kokulinganisa nokunyuka ekulinganisweni okuPrinta okufanele
Nansi ukucaciswa okulandelayo okulandelayo:
"Ngesikhathi ngizama ukwenza isithombe sibe i-PPI ephakeme, ngangilindele ukuthi izinombolo zamaphikseli zinciphise kunokuba zandise. Ngicabanga ukuthi ngicabanga ukuthi uma kungekho amaphikseli anele ukuze uthole usayizi engiwufunayo ngesinqumo engiyifunayo, ukusabalalisa 'ngandlela-thile, unganginikezi ngaphezulu. Manje njengoba ngifunde incazelo yakho yokuhlunga kabusha , ngiyaqonda ukuthi kungani kunephikseli engaphezulu, hhayi ngaphansi. "
Okushiwo ngokusabalalisa amaphikseli ngokuyinhloko kwenzekani uma uthumela ifayela eliyisisombululo esincane kuphrinta. Ngezinqumo eziphansi, amaphikseli athola kabanzi futhi alahlekelwa imininingwane; ema-pixel aphezulu ekuxazululeni ahlangene ndawonye, enza imininingwane eminingi. Ukunyathelisa kudala isofthiwe yakho ukudala amaphikseli amasha, kodwa ingenza ukuqagela kuphela ngokuqondene nalokho okunambile - ayikwazi ukudala noma iyiphi imininingwane ngaphezu kwalokho okwakukhona ekuqaleni.
