Introduction

I extracted the top left (x,y) coordinates using Hermitian’s favorite tool: Illustrator and converted them to pixels in a 300 DPI environment. This is done by dividing the numbers by 72 and multiplying them by 300. I then added to this the offset of the top left corner, which falls outside the mediabox. The resulting numbers ‘magically’ divide by 8 without any remainder.

I have a pretty good idea as to the why and how, but speculations like that are at this moment less relevant than getting the information to our poor friend Hermitian.

There is a (-6,-5) pixel offset in a 300 PPI system. The final two columns show the coordinates divided by 8. All of them are whole number and 3 of them do not align with a 16×16 grid. I erroneously had 45 for the 80 value…

Top left corner -1.44 -1.2 or  -6 pixels    -5 pixels in 300 ppi
