Hello,

I have an interesting question: I draw a square on a canvas using a
specific pixel size, lets say 400 x 200 px, width and height. I then
use the the Snip tool to take a screenshot of it and save it as a png
image. The png image ends up quite smaller in width and height, as
reported by the file properties dialog.

I was not expecting this difference. This is all on the same pc and
monitor so monitor pixel density/resolution should not matter.

Is there a way to make sure they are identical?

APL hackers do it in the quad.
