Description

Draws a line between two points. Use stroke() to change the color of something drawn with line().

Syntax

screen.line(xStart, yStart, xEnd, yEnd);

Parameters

  • xStart : int, the horizontal position where the line starts
  • yStart : int, the vertical position where the line starts
  • xEnd : int, the horizontal position where the line ends
  • yEnd : int, the vertical position where the line ends

Examples

#include <SPI.h>
#include <TFT.h> // Arduino TFT library

#define cs 10
#define dc 9
#define rst 8

TFT screen = TFT(cs, dc, rst);

void setup() {
// initialize the screen
screen.begin();

// make the background black
screen.background(0,0,0);

// set the stroke color to white
screen.stroke(255,255,255);

// draw a diagonal line across the screen's center
screen.line(0, 0, 160, 124);
}
