The silkscreen has been generated by taking a picture of the front of the Audi e-tron, converting it to gray scale and afterwards to black and white.

After this, I've let it pass by my edge detection algorithm and played with the filter to have the right amount of details of the e-tron.

After running the new picture in the bitmap converter tool from KiCAD, I had my Silkscreen that I could import on the PCB.
