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?
Wait a second... it looks like there's transparency involved in the
object the gradient is applied to and the canvas is most likely
transparent as well... is this possibly the issue with the PNG export?
In Inkscape it will render on the white (transparent) background, but,
the PNG would just have transparency w/o that "artificial" white. I
guess the quick test is to make the background opaque in the document
properties and test exporting to PNG again.
