Detect DPI information for a PNG image to determine if it's retina quality or not. This can be done by reading optional physical pixel dimensions chunk which both macOS and Windows attach to the image data.
import extract from "png-chunks-extract";
/**
* Detect if PNG image is in retina resolution.

I absolutely HATE the new Kippt. It sucks. It's 1,000 times harder to view my links. It makes me more inefficient, which is the opposite of what I hoped Kippt could do for me. Also, moving the search feature to the left side of the screen is plain idiotic. Most sites have inadvertently trained users to look for this feature in the upper right corner of the screen, so that's what users do. But you guys place yours in the least-popular place to set a search feature, so that it literally is the last place one will look when seeking it. I left delicious because I liked your (now old) design, but the only thing I liked about Kippt is long gone. This new design may have inspired high-fives from all the geeks that created it, but for the common user, this is an absolute FAIL. It is not intuitive and it certainly does not simplify my workflow. If it does not change back by next week, my account will be inactive and I'll find another site to use. Last thing, fire all the morons that had a say in approving this shit sa
