Good morning everybody,

I'm trying to calculate scale factors and it is a little bit confusing. So what 
is the unit of the sizes
returned by pageSize and pageSizeF? Is it dots?

And what is the unit of the parameters renderToImage(xres, yres)? Are those 
resolutions in dots/inch?

May be it's worth to improve the documentation at those to functions, because 
units are not
mentioned here. Or for pageSize and pageSizeF, I do not understand "i.e. 1/72th 
on an inch".

I'm asking that, because I want to be able to render a PDF page into an image 
with known height and width
in pixel.

Please add me to the cc, because I'm not a list subscribor.

I'm appreciate for any help!

Kind Regards,

Joachim
