What pixel dimensions do you want for your Tiff and what dpi?

With vector images, the larger you set the density before reading the 
pdf, the larger will be the pixel dimensions of your converted tiff.

For high quality, set the density before reading larger than you 
want, then resize to the pixel size you want (thus doing 
supersampling) and then set the density afterwards to what density 
you want.


convert -density X input.pdf -resize ... -density Y result.tiff
