Warning: obscure technical questions ahead!
Hey, Lazyweb, here's one for ya! I've got a 153-page PDF, made up mostly of high-rez raster images (8.5×11, 300DPI) with some vector text (page numbers a few blocks of text) here and there. I want to turn this into a .cbr file by bursting the PDF into individual PNGs or JPEGs and then RARing them, using Ubuntu and free tools. That's where you all come in: use the comments below to kibbitz — I've been playing with ImageMagick's "convert" tool all day (using lines like "convert -geometry 4414×3123 -density 300×300 -quality 100 pdf:original.pdf[1-153] converted.png") with no success. Either it churns for hours and nothing happens (is there a verbose mode for "convert"?) or the output is really low-rez and crummy.
