Ma injini amagawana - mndandanda wazinthu zofanana, ogwira ntchito, ma limits amodzi. Zomwe PDF zimawonjezera ndikuwona kuti fayilo iyenera kukhala fayilo ya fayilo ndipo pamene ikuyenera kukhala chinthu china, chomwe ndi chisankho chomwe chimapanga zinthu zambiri. Amayambanso kuchokera ku chinthu chimodzi za mtundu womwe uwu ndi dzina la siteyi: PDF ndi graph ya chinthu, si chithunzi cha tsamba, kotero malemba amakhala osankhika komanso vector amakhala olimba ngakhale kuti zinthu za raster zimachitika m'masamba.
Kodi ndiyenera kukhala ndi akaunti, ndipo kodi zinthu zina zimasunga?
