Print dimension too large
Posted: Fri May 20, 2011 11:38 am
Hi,
I need to print one or more pdf of technical drawings created by autocad. The customer saves them as pdf . I load them with GdPictureImaging , render as image, add some text and print it. The print is in A3 and i need to mantain ratio, because they are scale drawings for technical reason. we set dpi = 300 to maintain a good printing quality. Everything is right but print weight is around 48Mb from a 200-300kb pdf, and for it uses about 3 minutes to print a drawing (the printer not the print process). I can't find a way to reduce the weight of image without resizing or changing dpi in loadfromfile method ( the customer usually prints them at 600 dpi). Could you help? Maybe im wrong with something in printing theory or image processing.
