FontForge (formerly called PfaEdit) is a PostScript font editor which can create and modify outline fonts in Type 1, CID-Keyed, TrueType, OpenType format. It can generate bitmaps and save in BDF format or embedded bitmaps in TrueType/OpenType fonts. It can generate Type3 and SVG fonts if built with multilayer feature. If you feel the shortage of memory, rebuilding multilayer-disabled FontForge with FONTFORGE_NO_MULTILAYER defined will save some memory. If you have installed AutoTrace or Potrace, you can generate outlines from imported bitmap images. WWW: https://fontforge.org/
