Museum PDF 8 bit alignment

And the confirmations keep on piling up. Love it… If you know how to properly use Illustrator, it is not such a bad tool after all. But it never hurts double checking so I extracted the cm matrices and did the calculations using a simple spreadsheet and compared them with Illustrator. Oh and for Hermitian’s sake, you have to set the origin at the bottom left corner. Otherwise you will have to do a simple subtraction.

The museum PDF

(x0, y0) = (-3.36, -0.48) If you set the origin in Illustrator at the left bottom corner, the columns e-x0 and -(d+f-y0) match up.

And since waiting for Hermitian to figure out how to do this with his Illustrator tool, here are some examples
