I’ve been doing some experimenting with bitmap SVG colour fonts. My experiments led me to seeing what Fontself could do as it streamlines the image importing part of the process.
However I need to be able to further adjust things and tweak vertical metrics and opentype etc, this can’t be done in fontself. So I then open the .otf (24.7mb) generated by fontself and convert it to a glyphs file.
Once I’ve edited and renamed and remade things in glyphs I then export the .otf from glyphs but now i’m getting a much larger file size (Almost double 42.7mb)
I’m not adding any extra glyphs so I’m wondering why theres such a big variation in file size with glyphs adding so much data?
My process in converting the fontself .otf to a glyphs file means I open it and delete all the SVG layers and instead use the custom parameter ‘SBIX to SVG’ I then add some opentype, adjust some verticle metrics and fiddle with the naming a little. Nothing that should be adding a lot of data.
The thing I’ve noticed that could be linked to the file size is when I save the converted glyphs file the corresponding Image folder contains .tiff images that seem large, especially compared to the much smaller .svg images that are in the fontself .otf file.
Any ideas why glyphs exports much larger bitmap svg fonts?
Any help much appreciated.
