When “Pixel Preview” was activated, older versions used to show the pixelated glyphs also down in the preview area, but not anymore. Bug or feature?
BTW ist there a way to make the Pixel Preview show aliased glyphs, following the simple font rendering rules (pixel center inside the outline = pixel is filled)?
Thanks for the report. I fixed it.
I’ll see into the aliased drawing. Can you give me a good use case?
I could use it for a grid-based font to quickly check how it would render at a specific pixel size without any hinting, or that the pixels don’t change when tweaking the outlines.
I have already hacked up a quick plugin for that, but I thought maybe it would be easy enough to add the smoothing on/off switch to the existing pixel preview.
What algorithm do you use to do the pixelation?
I’m using NSBezierPath.containsPoint: for each pixel center. I haven’t yet checked if the result is realistic enough 
I added Glyphs.defaults["PixelPreviewAntialias"] = False. But I would not bet my live on the result. It uses the antialiased image and applies a 50% threshold (with a custom core image kernel, very nerdy, even for me). Slight changes in gamma can result in pixels flipping.
