What is a Bitmap Font?

A bitmap font stores each character (glyph) as a pre-rendered image in a texture atlas. This method ensures pixel-perfect rendering at a fixed size, which is highly efficient for performance-critical applications like games, embedded systems, and UIs where rendering speed and visual consistency are essential.
