Oh, I think I see what's going on. Inkscape has a defined "canvas
area", as indicated by the document outline thingee. Anything
overlapping or extending beyond that box is clipped when you export.
In your screenshot it's clear you can see there is portions of the
document extending beyond this boundary; it looks like inside the
boundary everything is identical for both images.
This is weird! When looking at the images with Firefox they indeed
appear to be (virtually) identical (apart from the border of course, I
just clipped a bit rough), but when I look at images with IrfanView (or
Corel PhotoPaint, I didn't try any other programs) they seem to be
different... (In fact, to make sure I wasn't going crazy I checked the
histograms, after cropping properly naturally, the mean value is off by
about 10.) Any gamma values or something similar being written to the
PNG file?
I'm using a color profile for my monitor btw, but I don't think that
should matter in this case (should affect both images in the same way
when displaying them and shouldn't be affecting the RGB values reported
for the image).
