I hope when you do add downsampling it will be optional. It is useful
when making a PDF for screen display to be able to include a high
resolution image that one can zoom into.

Don's right. Many places use PDF as the submission format for printing and the
publications department where I work uses it for archival. My thought would
be to have a check box "Maximum DPI" that had a text input ghosted unless
checked. Then the user could specify the max dpi that images would be down
sampled to.

Hmmm.... actually it needs more than that: it should have a drop down to
select the downsample method (e.g., none, linear and cubic). And it might
help folks to have a default for the dpi setting. Perhaps this could be
defaulted to the windowing system's DPI?
