yes..I'm talking about rasterized pdf; otherwise, I'll use sopdf instead.
Nook actually use Adobe ADE reader to display pdf. If the pdf is text, then changing font size to bigger ones will start to reflow the text.
I would confirm that my file is a rasterized one; and I was really surprised when I saw my cropped pdf displayed full page as if it were not cropped, when I set Nook font size to smaller, medium, bigger, or biggest.
In Nook, setting font size to small will display pdf in its original form, in other words, in what you intend your pdf file to be displayed (in this case, display only the cropped area). Setting font size to others, ie, smaller, medium, bigger, or biggest will display quite unpredictable result (in this case, display its before-cropped pages).
