Functions
void	dog_draw_rectangle (uint8_t x1, uint8_t y1, uint8_t x2, uint8_t y2, uint8_t size, char mode)

Detailed Description

This file contains the prototype for the dog_draw_rectangle() function, which is used to set or clear an unfilled rectangle.

Function Documentation

void dog_draw_rectangle	(	uint8_t	x1,
		uint8_t	y1,
		uint8_t	x2,
		uint8_t	y2,
		uint8_t	size,
		char	mode
	)

This function is used set or clear an unfilled rectangle of thickness 0 or 1.

Parameters

• x1 = X coordinate of the top-left corner of the rectangle.[0,127]
• t1 = Y coordinate of the top-left corner of the rectangle.[0,63]
• x2 = X coordinate of the bottom-right corner of the rectangle.[0,127]
• y2 = Y coordinate of the bottom-right corner of the rectangle.[0,63]
• size = The thickness of the point to place (0 or 1)
• mode = 's' for set, 'c' for clear

Algorithm

• Simply calls the fast line drawing functions dog_draw_v_line() and dog_draw_h_line() twice each to draw each side of the rectangle.

Assumptions

• None
