In this tutorial we are going to see how to read an image from a file. This is very useful when you want to store image files in your system and you want to use them to enrich the graphics of your application.

In order to read image from a file:

• You have to open a newFile in the image file.
• UseImageIO.read(file) to get an Image object.

 
 
 
Let’s see the code snippet that follows:

package com.javacodegeeks.snippets.desktop;import java.awt.Image;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;public class ReadImageFromFile {public static void main(String[] args) throws IOException {// input image fileFile file = new File("myimage.jpg");Image image = ImageIO.read(file);int width = image.getWidth(null);int height = image.getHeight(null);}}

 
This was an example on how to read image from a file.
