There is a very simple way to save a pdf presentation to individual jpeg images of the slides using convert.
convert -density 300 presentation.pdf presentation_page_%04d.jpg
where:
– density 300 specifies the DPI used to read the pdf.
– presentation_page_%04d.jpg is a name pattern for the saved images
As a result if presentation has 20 slides we get image slides like:
presentation_page_0000.jpg
…
presentation_page_0019.jpg
