You could do something along the lines of http://www.imagemagick.org/Usage/windows/#calc_fx, i.e. first Identify the dimensions of the PDF (using a standard resolution), then calculate the adequate resolution based on the result of this and than hand over this result to Convert.
The above link leeds to a Windows example, but the approach is similar (and probably even easier) under other operation systems. Wolfgang Hugemann _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
