I’m using msdfgen-atlasmsdfgen-atlas to generate the textures used by the renderer, and I wanted to experiment with to generate the textures used by the renderer, and I wanted to experiment with msdfgenmsdfgen’s parameters. Instead of generating new font data and then reloading the browser, I decided to try “headless” rendering controlled by a shell script.’s parameters.

The shadows of each letter overlap the previous letter. That’s because I’m drawing one letter at a time. So for example in the fl, I draw the f’s letter, outline, and shadow, , and I noticed another issue. The shadows of each letter overlap the previous letter.

Last timeLast time I was looking at letter spacing with my renderer to see how it compared to Google Chrome on Mac. But while doing that I noticed that their antialiasing looked nicer than mine. So I tweaked parameters, including antialias edge width, gamma, and threshold bias. I was looking at letter spacing with my renderer to see how it compared to Google Chrome on Mac.

In the previous postprevious post I described how I created outlines, and how I had a bug in the rendering. While looking closely at text to fix that bug, I noticed in one of my tests that the k and s seemed too close together. The h and e seemed a little too far...
