Hi, TypeDrawers. First post here.
I'm creating a pixel typeface. After looking at the many available open license fonts (a requirement for the project I'm working on) and not finding what I wanted, I decided to make something myself. I wasn't sure how to convert the pixel dimensions, but after reading
this tutorial from Glyphs, it seemed relatively simple. Party.
I made my grid spacing 100 and my UPM 1000. All of my sidebearings and character widths are multiples of 100. That should make it display on pixel at 10pt, right? This is how the exported font renders at 10pt @ 72 dpi in Photoshop.
But when I make it 20 pt (or 10pt @ 144 dpi), using 4 pixels per pixel:
Am I making some silly mistake?
In case it's helpful, I set my vertical metrics like this:

(Screenshots of your outlines might help.)
So, let this be a good lesson for anyone searching for a solution: don't autohint your pixel font?
Also, what could be a problem is where the corners of your outlines meet, e.g., in your c or s. They can confuse some renderers because technically, they constitute an overlap. This was a known problem with Flash, for instance, and counters (e.g., in the e or o) would be displayed filled. Inserting small outline bridges on such corners can fix this. There is a script called Flashify Pixels in my scripts repository on GitHub that does exactly that.
