Yini i-DPI i GIF ibonisa ngayo?

Okuzenzakalelayo yi-150 DPI (kulungile ukubukela isikrini kanye nokuphrinta okuningi). Izinketho ezithuthukisiwe zibonisa 72 (isithombe esincane se-web), 150 (okuzenzakalelayo), 300 (umgangatho wokuphrinta), kanye ne-600 (umgangatho ophezulu wokugcina). I-DPI ephezulu = icacile GIF kodwa amafayela amakhulu.

Ingabe ngizokhipha amakhasi athile kuphela we PDF njenge GIF?

Yebo — ikhasi-lokulinganisa lokukhethwa kukho lithatha izingeniso ezifana ne `1-5`, `1,3,5`, noma `zonke` ukukhetha ukuthi ziphi ikhasi le PDF ezibonisa ku GIF. Kuhle uma isigaba noma isiqephu se PDF eside kuphela esidingekayo.
