Font

Struct

Source: Font.h

Description

Descriptor for a bitmap font using 1bpp sprites.

A Font contains an array of Sprite structures, one for each character in the font's character set. Each glyph is rendered as a 1bpp sprite, allowing consistent rendering across platforms.

The font uses fixed-width glyphs for simplicity and performance. All glyphs share the same width and height, with spacing between characters controlled by the spacing field.

Font data should be stored in flash memory (const/constexpr) to minimize RAM usage on embedded systems. Include "Renderer.h" when using Font in implementation files to get the full Sprite definition.

Properties

Name	Type	Description
Sprite	const	Array of sprites, one per character (indexed by character code - firstChar)
firstChar	uint8_t	First character code in the font (e.g., 32 for space ' ')
lastChar	uint8_t	Last character code in the font (e.g., 126 for '~')
glyphWidth	uint8_t	Fixed width of each glyph in pixels
glyphHeight	uint8_t	Fixed height of each glyph in pixels
spacing	uint8_t	Horizontal spacing between characters in pixels
lineHeight	uint8_t	Total line height including vertical spacing (glyphHeight + vertical spacing)
