# I-pixal density calculator

### Yini ubukhulu be-pixel

Amaphikseli nge-intshi ngayinye (i-PPI) isilinganiso samandla we-pixel (isixazululo) samadivayisi ezimeni ezahlukahlukene: imiboniso ekhonjiswa ngamakhompiyutha, izikena zesithombe, nezinzwa zesithombe zekhamera yedijithali. I-PPI yesibonisi sekhompyutha ihlobene nosayizi wesibonisi ngamasentimitha kanye nenani eliphelele lamaphikseli kuzikhombisi-ndlela eziqondile nezime mpo.

### Okuningi ku-pixel density

Uma ufuna ukubala ukuminyana kwephikseli kwesikrini sakho, kuzofanele wazi: ukubala kwe-pixel okuvundlile nokumile nosayizi wesikrini sakho ohlukanisiwe. Ngemuva kwalokho sebenzisa le fomula, noma sebenzisa umshini wokubala wethu;)

$$d_p = \sqrt{w^2 + h^2}$$ $$PPI = \dfrac{d_p}{d_i} \ \$$ where

 $$w$$ ukulungiswa kobubanzi ngamaphikseli $$h$$ isixazululo sokuphakama ngamaphikseli $$d_p$$ ukulungiswa kwe-diagonal ngamaphikseli $$d_i$$ ngosayizi ohlangene ngamasentimitha (le yinombolo ekhangisiwe njengosayizi wesibonisi)

Uma ufuna ukwazi okuningi, hlola le vidiyo ye-Linus Tips engezansi.

### Ukuthuthuka okungokomlando kwe-PPI (uhlu lwamadivayisi)
