import from multi-page png, and automating pdf-> png

[Dr. Hawkins]

As I’m trying to get a temporary workaround for the engine pixel-rendering a pdf widget rather than including the pdf, I have a two part question:

1) is there a straightforward way to batch convert pdf to png of specified density?
2) for a multipage png, is there a “decent” way to use import to get a chunk of a specified page, or do I need to know the pixel height of the page and do the math?
