I’m using PdfRenderer.renderImageToDPI() and I’m trying to understand
exactly how the DPI is computed. From looking at the code, it seems
that 72 DPI is the default, meaning that it will have the same
resolution as the original document. Is this correct?
72dpi is like scale 1 with the methods that don't have "dpi" in it.
There is no such thing as "resolution as the original document". The
document could be pure vector graphics. There's only the target.
For thumbnails, a good strategy is to use 72dpi or above, then resize
the result image so it fits into target width / height.

I’m my application, I want to create a thumbnail image, but lower the
resolution so that the text is not really readable (even if you zoom
in), but one can still see the structure of the page. So I’m just
trying to understand the terminology
