coordToU8()

template<typename T>

fl::u8 fl::gfx::coordToU8 ( T alpha )

inline

sqrt is provided by fl::sqrt overloads in math.h for:

• All floating-point types (float, double)
• All fixed-point types (s8x8, s12x4, s16x16, s24x8, u8x8, u12x4, u16x16, u24x8)
• Integer types (via cast to float) Using: using fl::sqrt; (in drawStrokeLine template to find overloads via ADL) Convert a normalized [0,1] Coord value to u8 (0-255) for nscale8. Uses integer arithmetic for fixed-point types; float for float/double. Generic: for fixed-point types (those with .to_int())
