Checklist for Writing
Bitmap Fonts (1970s-1980s)
- Document bitmap font storage formats (BDF, PCF, custom binary)
- Explain glyph structure data organization and positioning metrics
- Detail 1-bit vs 8-bit storage efficiency and memory calculations
- Describe boolean matrix operations (get/set bit, bitmap conversion)
- Create rendering pipeline from bitmap to screen
- Explain texture atlas creation and optimization
- Analyze performance benefits (CPU vs GPU, cache efficiency)
- Document historical context (early terminals to modern usage)
- Write code examples (C structures, rendering functions)
- Compare advantages vs disadvantages with use cases
- Include technical terms (glyph, baseline, advance, kerning, hinting)
- Add mathematical formulas for storage calculations
Bitmap
Bitmap was introduced in 1970s.
The idea is to fill colors in a grid of pixels to show the letter.
A boolean matrix can be used where the background color represents true or 1
and the text color represents false or 0.
In here the letters are made on a pixel grid of 16 X 20.
Where the black colored cells are 1 and the non-black colored cells are 0.
