## fill

#### Description

Called before drawing an object on screen, it sets the fill color of shapes and text.

fill() 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.fill(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> // 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.fill(255,255,255);
// draw a white box in the screen center
screen.rect(screen.width()/2+10,screen.height()/2+10,screen.width()/2-10,screen.height()/2-10);
}
void loop() {
}
