PNG Font Generator

Bitmap font generator with uniform character spacing.

Options:
  -f, --font TEXT                TTF font file  [required]
  -s, --size INTEGER             Font size
  -w, --cell-width INTEGER       Cell width
  -h, --cell-height INTEGER      Cell height
  --v-align [top|center|bottom]  Vertical alignment
  --h-align [left|center|right]  Horizontal alignment
  --color INTEGER RANGE...       Text color in RGBA format
  --background INTEGER RANGE...  Background color in RGBA format
  --debug                        Enables drawing grid line

Example

python pngfont.py input.txt out.png --font=IBMPlexMono-Medium.ttf --cell-width 16 --cell-height 24 --size 18

The contents of an input file is:

0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijlmnopqrstuvwyz().,?!-@#^&/
АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯ
