MSX Font Editor

  A MSX's font editor for PC and screens 0/1 mosaic creator.

  1. Introduction

  This project aims at developing a font editor for PC, where it is possible to read, edit and save MSX 8x8 fonts.

  In addiction, the editor is able to render PC fonts to export them in MSX format and generate character mosaics for screens 0 and 1.

  It is based on the old Alfabeto Plus project, using a modern programming environment like Java, improving the program, the interface and introducing the character mosaic tool.

  2. The Prototype
  The Alfabeto Plus was the prototype developed for reading, modifying and saving MSX 8x8 character fonts. Thus, it was able to render PC fonts and export them to MSX.


  How to use:

  Alfabeto Plus was quite simple to use:

  - Abrir: opens a MSX 8x8 file font.
  - Salvar: saves a MSX 8x8 file font.
  - Importar: imports a Windows font to editor.
  - Fonte a importar: select an intalled font from Windows to import to the editor.
  - b: applies the boldface to the imported font.
  - i: applied the italic style to the imported font.
  - Controle de posicionamento: manual positioning control to ajust the imported font.
  - <<: updates the edited letter to the font area.

  3. Current version: MSX Font Editor
  This program was coded in Java language and it is able to run in several platforms using the same binary file.


  The program interface is quite simple and intuitive to use, presenting buttons with icons and tooltips.

  Major news:

  • Now it is possible to open and edit several fonts at the same time without loosing the work. This is due to the fact of each font has it own buffer, where it is possible to undo or redo the last operation in both font and character areas.
  • The PC font rendering algorithm is now able to fit properly the characters on their spaces, without being necessary to make manual adjustments.
  • The new mosaic tool makes possible to generate images on screens 0 and 1.
  • From version 1.3, may 2020:
    • Possible of multiple character selection.
    • Mouse drag enabled to multiple selection.
    • Mouse drag enabled to fill/erase character's pixels.
    • Possible to copy and paste characters between fonts.
    • Possible to modify only selected characters.

  The great new feature is the mosaic tool, where it is possible to import monochromatic images from PC (black & white) and place them at ASCII table, making possible to generate image mosaics on screens 0 and 1.
