Arduino Function: TFT.image

Description

Draws an image from the SD card in the screen at a specified location.

Syntax

screen.image(image, xPos, yPos);

Parameters

  • image : a named instance of PImage.
  • xPos : int, location on the x-axis to start drawing
  • yPos : int, location on the y-axis to start drawing

Examples

// this example looks for a file named "logo.bmp"
// on the SD card, and renders it to the screen
#include <Esplora.h>
#include <SPI.h>
#include <SD.h>
#include <TFT.h> // Arduino TFT library

#define SD_CS 8 // Chip select line for SD card in Esplora

PImage logo;

void setup() {
// initialize the screen
EsploraTFT.begin();
// initialize the SD card
SD.begin(SD_CS);
// set the background the black
EsploraTFT.background(0, 0, 0);

// load the image into the named instance of PImage
logo = EsploraTFT.loadImage("arduino.bmp");

// if it is a valid image file, turn the Esplora's LED green
if (logo.isValid()) {
Esplora.writeGreen(255);
}
else{
// if it is not valid, turn the LED red
Esplora.writeRed(255);
}

// draw the image on the screen starting at the top left corner
EsploraTFT.image(logo, 0, 0);

}

void loop() {
