After you import your bitmap, go into the "Document Properties..." dialog and select "Fit Page to Selection".
After you annotate your image, you can export to PNG and it will be the same size as your original image.

I would like to use Inkscape as a screenshot illustrator (image editor). I have a bitmap, a software interface capture for example, and would like to draw some vector objects over it. However I can't find the proper zoom level to display the bitmap properly (at 100% or 200% it randomly works, it depends of the screenshot size) and more important, export it so the result is not "jagged". The zoom level, even at 100% (1:1) is never correct as Inkscape doesn't consider the canvas as a bitmap, as The GIMP does for example, but as vector. The only solution I found is to set the exported bitmap dimensions to 90 ppp but I'm not sure it works in all cases. I don't even know why 90 works, I suppose it balances the bitmap/vector ratio.
I guess I'm looking for some sort of hybrid mode between bitmap and vector image editing.
