Yenza Izithombe Zakho Zibe Nkulu Ngokulahlekelwa Okunciphile Kwekhwalithi
Enye yemibuzo evame ukubuzwa ngokuphathelene nesofthiwe yehluzo yindlela yokwandisa usayizi wesithombe ngaphandle kokuthola imiphetho emibi neyigcwele. Abasebenzisi abasha bavame ukumangala lapho beshintsha isithombe bese bethola ukuthi ikhwalithi idlwengulwe kakhulu. Abasebenzisi abanolwazi bajwayele inkinga. Isizathu sokukhohlakala kungenxa yokuthi izinhlobo ze- bitmapped , noma i-raster, zithombe zilinganiselwe ngesinqumo se-pixel yabo. Uma uzama ukushintsha lezi zithombe, isofthiwe yakho kufanele ikhulise usayizi wepikelli ngayinye - okuholela ekufanekisweni kwesithombe - noma kufanele "ukuqagela" ngendlela engcono kakhulu yokwengeza amaphikseli esithombeni ukuze ukwenze kube mkhulu .
Kungekudala, azikho izinketho eziningi zokwandisa isinqumo ngaphandle kokusebenzisa izindlela zakho zokuhlunga ezakhelwe ngaphakathi kwesoftware. Namuhla, sibhekene namathuba amaningi kunanini ngaphambili. Yiqiniso, kungcono kakhulu ukuthatha isinqumo osidingayo kusukela ekuqaleni. Uma unenketho yokucwaninga isithombe ngesinqumo esiphezulu, nakanjani, kufanele wenze lokho ngaphambi kokusebenzisa izixazululo zesofthiwe. Futhi uma unayo imali yokufaka ikhamera enezinqumo eziphakeme, ungase uthole ukuthi imali isetshenziswe kangcono kunokuba ungayifaka kwisixazululo se-software. Uma usho lokho, zivame izikhathi lapho ungenakho okunye ukhetho kunokuba usebenzise isofthiwe. Uma leso sikhathi sifika, nansi ulwazi olufanele ukwazi.
Ukuvuselela ngokumelana nokuPhakamisa
Isofthiwe enkulu inomyalo owodwa kokubili ukuguqula nokusetha kabusha. Ukuvuselela isithombe kuhilela ukushintsha ubukhulu bokuphrinta ngaphandle kokushintsha ubukhulu bephikelel. Njengoba isinqumo senyuliwe, usayizi wokuphrinta uba mncane, futhi ngokuphambene nalokho. Uma ukwandisa isixazululo ngaphandle kokushintsha ubukhulu bamaphikseli, akukho ukulahlekelwa kwekhwalithi, kodwa kufanele unikeze usayizi wokuphrinta. Ukuvuselela isithombe usebenzisa ukuhlunga, noma kunjalo, kuhilela ukuguqula ubukhulu bephikelel futhi kuzohlala kuveza ukulahlekelwa ngekhwalithi. Kungenxa yokuthi ukuphinda kusetshenziswe kusetshenziswa inqubo ebizwa ngokuthi ukubhalwa kwamagama ngokukhulisa usayizi wesithombe. Inqubo yokubamba iqhaza ilinganisa amanani ama-pixel isofthiwe idinga ukudala ngokusekelwe kuma-pixel akhona esithombeni. Ukumisa kabusha ngemiphumela yokubamba iqhaza ekugqaseni okukhulu kwesithombe esishintshiwe, ikakhulukazi ezindaweni lapho kukhona imigqa ebukhali nezinguquko ezihlukile embala.

Esinye isici salolu daba ukuphakama kwe-smartphone kanye ne-tablet kanye nokugxila okuhambisanayo kumaphikseli wedivayisi. . Lawa madivayisi aqukethe amaphikseli amabili kuya kwamathathu esikhaleni esifanayo esiphethwe i-pixel eyodwa esikrinini sakho sekhompyutheni. Ukuhambisa isithombe kusuka kwikhompyutha yakho kuya kudivayisi kudinga ukuthi udale izinguqulo eziningi zesithombe esifanayo (isib. 1X, 2X no-3X) ukuqinisekisa ukuthi zibonisa kahle kudivayisi. Ingabe omunye ukwandisa ubukhulu besithombe noma ukwandisa inani lamaphikseli.
Izindlela Zokuxhumana Zomphakathi Ezivamile
Isofthiwe yokuhlela isithombe ngokuvamile inikeza izindlela ezimbalwa zokubhaliwe zokubala zokubala amaphikseli amasha uma isithombe sisithwetshiwe. Nazi izincazelo zezindlela ezintathu ezitholakalayo ku-Photoshop. Uma ungasebenzisi i-Photoshop, isofthiwe yakho mhlawumbe inikeza izinketho ezifanayo nakuba zingasebenzisa i-terminology ehlukile.
- I-bicubic ihamba kancane kodwa ikhiqiza ukulinganisa okungcono kwamanani we-pixel amasha.
- I-Bilinear iyashesha kunokuba ibicubic, kodwa yenza umsebenzi ompofu. Kokubili ukubhalwa kwe-bicubic ne-bilinear kubangelwa isithombe esicacile, ikakhulukazi uma uphromotha.
- Umakhelwane oseduzane akasebenzisi i-interpolation. Ivele ithatha ukubaluleka kwamaphikseli angomakhelwane futhi ineza amaphikseli amasha ngaphandle kokubala. Yilokho lapho uthola khona i-jaggies noma isitezi-isinyathelo-sinyathelo.
Qaphela ukuthi kunezingcingo ezingaphezu kwalezi zindlela ezintathu zokubhaliwe futhi ngisho nokusebenzisa indlela efanayo kufthiwe ehlukile kungaveza imiphumela ehlukile. Esihlangenweni sami, ngitholile ukuthi i-Photoshop inikeza ukubhalwa kwe-bicubic engcono kunoma iyiphi enye isofthiwe engiyiqhathanise nayo.
