### Boima ba pixel ke eng

Li-pixels ka lisenthimithara (PPI) ke litekanyo tsa letsoalo la pixel (resolution) ea lisebelisoa maemong a fapaneng: hangata lipontšo tsa likhomphutha, li-scanner tsa litšoantšo le li-sensor tsa litšoantšo tsa kh'amera PPI ea pontšo ea komporo e amana le boholo ba pontšo ka lisenthimithara le palo ea lipikselse ka tsela e otlolohileng le e otlolohileng.

### Ho eketsehileng ka palo ea pixel

Haeba o batla ho bala palo ea pixel ea skrineng sa hau, o tla tlameha ho tseba: lipalo tsa pixel tse otlolohileng le tse emeng le boholo ba skrine ea hau e kopaneng. Ebe u sebelisa foromo ena, kapa u sebelise khalekhuleita ea rona

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

 $$w$$ qeto ea bophara ka lipikselse $$h$$ resolution ea bophahamo ka pixels $$d_p$$ ke qeto e kopaneng ka pixels $$d_i$$ e boholo ba diagonal ka lisenthimithara (ena ke palo e phatlalatsoang ka boholo ba pontšo)

Haeba u batla ho tseba le ho feta, sheba video e hlollang ea Malebela a Linus ka tlase.
