Kalkuletar girman hoton da za a buga
Yaya girman hotona zai kasance idan an buga shi da PPI da na zaɓa?
Ƙididdige faɗi, tsayi da fili na zahiri daga ma'aunin piksel ba tare da ƙara ko cire piksel ba.
Piksel na hoto da cunkoson da ka zaɓa
Yi amfani da ma'aunin piksel na fayil ɗin hoton. Zaɓi PPI mai kyau da kanka; cunkoso iri ɗaya yake a kwance da a tsaye.
Yadda ake samun kimantawa
Raba kowane ma'aunin piksel da piksel a kowace inci da ka zaɓa don samun inci. Ninka inci da 2.54 don santimita. Fili yana amfani da adadin piksel biyu na asali da PPI murabba'i. Ninka adadin piksel biyu don samun jimilla.
W = w ÷ PPI · in
H = h ÷ PPI · in
cm = in × 2.54
A = w × h ÷ PPI² × 2.54² · cm²
pixels = w × hLissafin siffa kawai, da PPI iri ɗaya a hanyoyin biyu da adadin piksel marasa canji. Ba a yanke hoto, sake samfurin piksel, ƙara firam, ƙarin gefen yankewa ko tazarar gefen firinta ba. Ba ya ba da shawarar PPI, ba ya tantance kaifin hoto, kuma ba ya lissafa ɗigon firinta a inci, girman fayil ko allo. Sikelin bugu na iya sauya girman zahiri; ba a tabbatar da girma ko ingancin sakamako ba.
