Arduino Function: TFT.PImage.height

Description

It returns the object's height.

Syntax

image.height();

Returns

 int : the image's height in pixels

Examples

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

void loop() {
// randomly draw the image on screen
int x = random(EsploraTFT.width() - logo.width());
int y = random(EsploraTFT.height() - logo.height());
EsploraTFT.image(logo, x, y);
delay(1500);
}
