It was created with the latex source below and pdflatex. I then opened it with epdfview, found its window id with xwininfo -children, took a screenshot of it with ImageMagick's import -window id euler.png, cropped the resulting euler.png with the GIMP, and here we are! (A kludge, yes, but I couldn't figure out how to get a high resolution image with convert euler.pdf euler.png).
Here's the latex source:
