Ingabe ngithola isithombe esisodwa ngamakhasi?

Yebo - ikhasi ngalinye libonisa njengehele layo PNG futhi iset ifika njenge ZIP. Ikhasi-lokulinganisa ukhetho linciphisa lapho ufuna nje isigqoko noma isiqephu esisodwa, futhi limisa kukhasi elilodwa libuyisela ifayela elilodwa endaweni yokugcina.

Yini i-DPI i PNG ibonisa ngayo?
