FZX Font Editor


FZX Editor has been initiated by Andrew Owen, who worked with Einar Saukas and some others on a font driver system for the ZX-Spectrum that supports proportional text simply with PRINT # commands.

FZX editor edits usual CHR fonts (768 bytes) and the FZX file fonts directly. You have several tools like drawing lines, ellipses, rectangles, flipping, and rolling tools.

Fully supported file types (reading and writing):

  • FZX files
  • CHR files (768 bytes)

Partially supported file types (saving as only):

  • ASM files

Working features:

  • Edit all chars of your font with a scaleable grid. 
  • Use line, ellipse, rectangle tools for drawing
  • Use the copy tool to copy a rectangular range into the Windows clipboard
  • Use the paste tool to paste any image from Windows clipboard into the grid
  • Flipping and rolling tools
  • Text preview with customizeable text
  • Big undo/redo buffer
