pdf to tif:poor resolution

[gabriello]

Hello:
I'm newbie with ImageMagick, I have a monochrome CAD draft printed to pdf, and I loke to convert it to a Tif picture, I tried:
convert toto.pdf -monochrome toto.tif
the result is a tif file with a very poor resolution, how can I improve quality??

Thank you

Specify a density (dpi) for the PDF before reading it.

Code: Select all

convert -density 300 toto.pdf -monochrome toto.tif

thank you for the tip, it works great.
But I noticed that straight lines are converted with too many notches, (which become smaller with increasing density)
can a straight line in pdf, be converted to a straight line in tif?

Thank you
