Detailed Description

Fixed-cell bitmap font model and text metrics.

Provides a compact fixed-cell font representation and text measurement. Rendering lives in the Graphics Component component; bundled fonts are published as separate data packages (e.g. idfxx_font_spleen), each font in its own translation unit so fonts an application never references are dropped at link time. A BDF-to-C converter script for adding more fonts is included under scripts/.

Function Documentation

constexpr size_t idfxx::font::text_width ( const mono_font &  font, std::string_view  text, unsigned  scale = 1  )

constexprnoexcept

Returns the width in pixels of text rendered in font.

Sums the advance of every character in text; characters outside the font's glyph range advance like any other (rendered blank).

Parameters

font	The font.
text	The text to measure.
scale	Integer magnification factor (>= 1; 0 is treated as 1).

Returns

The rendered width in pixels.
