stroke()
Description
Called before drawing an object on screen, it sets the color of lines and borders around shapes.
stroke() expects 8-bit values for each of the red, green, and blue channels, but the screen does not display with this fidelity. The red and blue values are scaled to 5-bit color (32 discrete steps), and the green is 6-bit color (64 discrete steps).
Syntax
screen.stroke(red, green, blue);
Parameters
red: int 0-255
green: int 0-255
blue: int 0-255
Returns
none
Example
#include <SPI.h>
#include <TFT.h>
#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 box with a white outline in the middle of the screen
screen.rect(screen.width()/2+10,screen.height()/2+10,screen.width()/2-10,screen.height()/2-10);
}
void loop() {
}
