I did some testing with the command line side and the magick.net isn't far off. I ended up getting 1.06MB with the command line instead of 1.38MB with Magick.NET.
The starting pngs for the cli generated pdf were 199KB and 86.7KB which is about a third of the final pdf. I might try using one bit images instead of grayscale to see what I can squeeze out. I just got a little freaked out when the 6 page D size drawing comparisons were getting close to 11MB.
Thanks for the reality check. Wish there was a way to have the PDF be just twice the size of the pngs. Makes me think the pngs are uncompressed when they're stored in the pdf.
