Re: How to automatically figuring out the optimal resolution for a pdf file?

And how would acrobat do that!  That is the question!

PDF's (or postscript) are not supposed to have a 'ideal density' or
resolution. But if they contain raster images, those raster images may
have a ideal resoltuion.  However a PFD could easily have multiple
rasters each with different ideal resolution. 

So how any program can pick an ideal resolution is beyond me!

Hi,

I'm trying to converting a pdf without explicitly specify the density
as Acrobat can automatically figure out the best resolution. But it
seems that convert can not do so correctly, it use a far too low
resolution. I'm wondering if there is a way to automatically determine
the best resolution. (Let is assume the pdf was created by converting
from a tif file. the optimal resolution is just the resolution of the
original tif file.)

convert image.pdf +adjoin image_%02d.tif
