When creating a new font from Art Nouveau images I arrived at this character which was verrrry slow to open (Edit). When it finally displayed some time later, I could see why – Scroll down!
Those gray areas were thousands of tiny shapes. I don’t believe those images are supposed to be faces, but I’ll never find out…
I’ve given up trying to work very large glyphs – more than 32k points since FontLab blue screens when trying to read them. My other font friends get mad if I send them one of these.
