Overlapping The Images


This example will help you to understand the concept of Graphics2D better. Just go through the example provided next and see the result. I believe example itself is self-explanatory.

As usual if you have any doubts,clarifications etc you can ask me.

Program :-

package client;

import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class OverlappingImage {
    public static void main(String args[]) {
   
        BufferedImage image1 = null;
BufferedImage image2 = null;
try {
image1 = ImageIO.read(new File("C:/temp/Winter.jpg"));
image2 = ImageIO.read(new File("C:/temp/Sunset.jpg"));
} catch (IOException e) {
e.printStackTrace();
}

Graphics2D g = image1.createGraphics();
        g.drawImage(image1, 0, 0, null);
        g.drawImage(image2, 100, 10, null);
       
        File file = new File("C:/temp/overLayedImage.jpg");
            try {
ImageIO.write(image1, "JPG", file);
} catch (IOException e) {
e.printStackTrace();
}
            System.out.println("Check the new overlapped image");
    }
}

Screenshot of output is given below.

Mini Project for Image Processing Beginners

A short project for Engineering graduates. Take an MRI Scanned image or a X-Ray image of healthy person as well as a patient and compare the pixel values, edges etc. This will help you understand the general values of a healthy body. Using that as mean or median, try to create an diagnoses software using these images as input. I will add the sample code or algorithm for your reference. So keep checking the blog for more.

Program to convert image byte array to PDF

Simple sample program to convert image byte array to PDF         //input path. path where byte array is saved         String pathOfByteArrayFile = "/home/inputByteArray.txt";         //output path. path where rendered you need to save . Output PDF should render properly         String outputPDFPath = "/home/output.pdf";         try         {             File file = new File(pathOfByteArrayFile);             FileOutputStream fout = new FileOutputStream(outputPDFPath);             byte[] bArray = Base64.decode(FileUtils.readFileToByteArray(file));             fout.write(bArray);             fout.close();             assertFalse(false);         }   ...

Program to convert base64 to Image and vice versa

Code snippet: This method decodes the base64 string into the bytes and converts it into an image .      * Note: this method expects input to be an encoded Image in base64 format. It can't work with other other files encoded in base64 format ByteArrayInputStream bis = new ByteArrayInputStream(Base64.getDecoder().decode(base64data)); BufferedImage img = ImageIO.read(bis); bis.close(); This method encodes the PNG image to base64 format ByteArrayOutputStream output = new ByteArrayOutputStream(); ImageIO.write(image, "PNG", output); String encodedString = Base64.getEncoder().encodeToString(output.toByteArray()); output.close();
