HotPDF iscrtava vektorsku grafiku tako da izgrađuje putanju na trenutnoj stranici (current page), a zatim nalaže njezino ocrtavanje (painted). Između se ne događa izrada bitmape (bitmap step). Crta koju nacrtate funkcijama MoveTo i LineTo, u toku sadržaja na kraju biva upisana pomoću PDF operatora za putanju, ostajući vjerna pravom vektoru: nadasve je britka na razini uvećanja 50%, a istovremeno jednako besprijekorno oštra sa uvećanjem koje doseže 1600%, dok veličinom iznosi sićušni i znatno manji udio naprama rasteriziranoj varijanti koja bi zauzela više.
