ITPEC FE Morning April 2023 Question 23
ITPEC FE Morning April 2023 — Question 23 of 80
Outline Fonts vs Bitmap Fonts — when to use vector-based (outline) fonts over pixel-based (bitmap) fonts.
Outline fonts store characters as mathematical curves (vectors), while bitmap fonts store them as fixed pixel grids.
Key difference:
- Outline fonts → scalable without quality loss → suitable for enlarging characters by a scale factor
- Bitmap fonts → fixed resolution → faster rendering but pixelated when scaled
Why not others:
- (a) Display quickly — bitmap fonts render faster (no curve calculation needed)
- (b) Monospace — fixed-width spacing is unrelated to font storage format
- (c) Single-byte and double-byte — character encoding issue, not a font format issue
Key rule: If the question involves scaling, resizing, or enlarging text → outline fonts. If it involves speed or fixed-size display → bitmap fonts.
