// (1)
constexpr auto setPoint(const std::size_t point_) noexcept;

// (2)
constexpr auto setPoint(const std::size_t point_x_, const std::size_t point_y_) noexcept;

Overview

Set the drawing start point coordinates (X, Y).

Return Value

The return type is a reference value of this class.

Exception

Don't throw exception.

Computational Complexity

Constant time.

Example

#include <DTL.hpp>
#include <iostream>
#include <cstddef>
#include <cstdint>

int main() {

	using shape_t = std::uint_fast8_t;
	constexpr std::size_t width{ 16 };
	constexpr std::size_t height{ 8 };

	shape_t matrix[height * width]{};

	dtl::shape::Border<shape_t> border(1);

	border.setPoint(5, 3).drawArray(matrix, width, height);

	std::cout << "PointX:" << border.getPointX() << '\n';
	std::cout << "PointY:" << border.getPointY() << '\n';

	dtl::console::OutputNumber<shape_t>(",").drawArray(matrix, width, height);
	dtl::console::OutputString<shape_t>("//", "##").drawArray(matrix, width, height);

	return 0;
}
