Kubara ubucucike
Ubucucike bwa pigiseli ni iki
Pixels kuri santimetero (PPI) ni igipimo cya pigiseli yubucucike (imiterere) yibikoresho mubice bitandukanye: mubisanzwe kwerekana mudasobwa, gusikana amashusho, hamwe na sensor ya kamera yerekana amashusho. PPI yerekana mudasobwa ifitanye isano nubunini bwerekana muri santimetero n'umubare rusange wa pigiseli mu cyerekezo gitambitse kandi gihagaritse.

Byinshi kuri pigiseli yuzuye
Niba ushaka kubara pigiseli yuzuye ya ecran yawe, ugomba kumenya: ibara rya horizontal na vertical pigiseli ibara hamwe nubunini bwa ecran ya diagonal. Noneho koresha iyi formula, cyangwa ukoreshe calculatrice;)
\(
d_p = \sqrt{w^2 + h^2}
\)
\(
PPI = \dfrac{d_p}{d_i} \ \
\)
where| \( w \) | ni ubugari bugaragara muri pigiseli |
| \( h \) | ni uburebure bwa pigiseli |
| \( d_p \) | ni diagonal ikemurwa muri pigiseli |
| \( d_i \) | ni ubunini bwa diagonal muri santimetero (iyi niyo mibare yamamajwe nkubunini bwerekana) |
Niba ushaka kumenya byinshi kurushaho, reba iyi videwo iteye ubwoba ya Linus.
