Member Function Documentation

fill()

template<template< size_t, size_t, bool, bool > class T, size_t W, size_t H, bool GRAYSCALE, bool USE_SPAN>

rect & constixel::shapes::rect< T, W, H, GRAYSCALE, USE_SPAN >::fill ( uint8_t col )

inlineconstexpr

Fill the rectangle with a solid color.

Parameters

col	Color value

Returns

Reference to this rectangle for chaining

fill_shader()

template<template< size_t, size_t, bool, bool > class T, size_t W, size_t H, bool GRAYSCALE, bool USE_SPAN>

template<typename shader_func>
requires std::is_invocable_r_v<std::array<float, 4>, shader_func, float, float, int32_t, int32_t>

auto constixel::shapes::rect< T, W, H, GRAYSCALE, USE_SPAN >::fill_shader ( const shader_func & shader ) -> rect &

inlineconstexpr

inlineconstexpr

Draw the rectangle outline.

Parameters

col	Color value
stroke_width	Width of the stroke (default: 1)

Returns

Reference to this rectangle for chaining
