[poppler] pdftoppm vs. pdftocairo

[Denny Reeh]

Hello,

i'm using pdftoppm -png to convert a pdf to png for showing in web browsers.
now, with the poppler release 0.17.3 pdftocairo was introduced.

what are the differences between "pdftoppm -png" and "pdftocairo -png" ?

Thanks,

Regards Denny Reeh
