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. Bitmap Font 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.
