Set BufferedImage to be a color in Java

Question

I need to create a rectangular BufferedImage with a specified background color, draw some pattern on the background and save it to file. I don\'t know how to cr

Answer 1

For who want also to save the created image to a file, I have used previous answers and added the file saving part:

import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.color.ColorSpace;
import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;

// Create the image
BufferedImage bi = new BufferedImage(80, 40, ColorSpace.TYPE_RGB);
Graphics2D graphics = bi.createGraphics();

// Fill the background with gray color
Color rgb = new Color(50, 50, 50);
graphics.setColor (rgb);
graphics.fillRect ( 0, 0, bi.getWidth(), bi.getHeight());

// Save the file in PNG format
File outFile = new File("output.png");
ImageIO.write(bi, "png", outFile);

You can also save the image in other formats like bmp, jpg, etc...
