Use FontForge to load up .OTF file (in the weight of choice). 25 | 1. Force encoding through `Encoding > Force Encoding > ISO 8859-1` 26 | 1. Generate bitmaps through `Element > Bitmap Strikes Available` 27 | 1. Generate font through `File > Generate Fonts...` after selecting BDF output 28 | 29 | _(Don't worry too much about the other options, as a hand-edit in Part II will take care of things.)_ 30 | 31 | ### Part II—Fix generated BDF files [BDF font format](https://en.wikipedia.org/wiki/Glyph_Bitmap_Distribution_Format) 32 | 33 | Now the BDF will have a couple of things that will trip up vtfontcvt-ng: 34 | 35 | 1. The dreaded `font spacing "C" (character cell) required` error. 36 | 1. `bitmap with unsupported DWIDTH`. 37 | 1. Even after you fix this you might/will get `PIO_FONT: Invalid argument`. 38 | 39 | A couple of edits in the BDF will solve this: 40 | 41 | 1. `FONTBOUNDINGBOX ` has to match all the `DWIDTH ` lines below (or x2 according to source, but we'll put that aside). This will require some hand-tuning because if you change fbbw to match dwidth the characters will be scrunched; and if you change dwidth to match fbbw, then your characters will be spaced too far apart. Anyway the important thing is that they match. 42 | 1. The other edit was to delete all characters after 255. The `STARTCHAR` might be descriptive or not (IBMPlexMono has it as _ydieresis_), but just delete all of the remaining chars while leaving the final `ENDFONT` line in place. In the case of IBMPlexMono, I simply searched for `ENCODING 256`; selected from the previous `STARTCHAR` line to the penultimate line; and then deleted that selected block, leaving the `ENDFONT` line intact. 43 | 1. In `FONT` line ensure that `SPACING` as per X- logical font description is 'C' for _Character Cell_ \(See: [X logical font description](https://en.wikipedia.org/wiki/X_logical_font_description)\). And also ensure that the line that explicitly states `SPACING` matches with a corresponding 'C'. 44 | 45 | ## Part III—Install FNT files 46 | With these changes go ahead and run the usual commands to install: 47 | 48 | ``` 49 | $ vtfontcvt-ng IBMPlexMono/IBMPlexMono-Light-14.bdf fnt/IBMPlexMono-Light-14.fnt 50 | $ sudo cp fnt/*.fnt /usr/share/vt/fonts 51 | $ sudo vidcontrol -f /usr/share/vt/fonts/IBMPlexMono-Light-14.fnt # While in vt, and not in X- 52 | ``` 53 | 54 | That should give you a path to a font of choice. Of course, this doesn't ensure that the generated font will be at all aesthetically pleasing, and certainly won't be as nice as a handcrafted bitmap font. But it did allow me to get a decent approximation of IBMPlexMono under vt. 55 | 56 | Regards. 57 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Creative Commons Legal Code 2 | 3 | CC0 1.0 Universal 4 | 5 | CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE 6 | LEGAL SERVICES.
