Render at 300 DPI

Hi,

I am not sure if this is possible, but is there a way I create a big texture (8.5’x11’ = 2550 x 3300px)  so I can create in it object like text, rect, circle and then save the result as a file ? With or without transparent background.

Pretty much, the ability to create an arbitrary texture size and save it to disk ?

thank you

Nick
