The image in the main README showcases a screenshot of a retina display with a figure displayed inline in iTerm2. How to do this? All my attempts result in pixelated images.

I'm not quite sure what you are asking, could you supply a screenshot of the problem?

Go ahead and pixel peep at it at 1:1 scaling. Text is nice and smooth, using full retina abilities, whereas the image is pixelated, due to retina not being scaled. The exact same happens with itermplot figures: they are not retina. You somehow were able to make them retina, as is shown in the screenshot in the main README.

Currently, itermplot defaults to generating PDF images for transfer to iTerm2 and there seems to be a bug in iTerm2 around retina rendering that is now fixed in the beta and nightly builds. See here.

Alternatively, you can set export ITERMPLOT_PLOTFILE="plot.png" to use the PNG backend. This should help achieve what you want and then you can also tweak the DPI settings. See here.
