line
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
Returns
none
Example
#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);
}
void loop() {
}
