How to convert PDF to PNG and cut each page to half?

[rondesta]

Hi,

I'm trying to convert a PDF file. The file is a presentation that each page contains 2 slides.
I want to convert it in way that I'll get PNG for every slide (not page).

I tried:

Code: Select all

convert file.pdf file.png

but it creates a PNG for every page.
I assume that I need to use one of the functions to cut each page to half (relatively to the height) but I don't know which one.

Thanks,

Ron.

I figured it out:

Code: Select all

convert -crop widthXheight file.pdf file.png

Try -crop 2x1@ instead That will not need you to pre-calculate the size, but divide the image in two as equally as possible.

There are also options to add some overlap to the two halves
