Get Image from Pixels using Java

We will see how we can read an image using Java. We know there are several kinds of image formats such as JPEG, GIF, PNG, BMP, TIFF etc. Java has built-in Image I/O API in javax.imageio package and it can be used to load external image formats into its BufferedImage formats. By default, Image I/O supports image formats such as JPEG, PNG, GIF, BMP, WBMP. It can also be extensible to support additional image formats for TIFF and JPEG 2000.

Image I/O recognizes the contents of the file as a JPEG format image, and decodes it into a BufferedImage which can be directly used by Java 2D.

Image can be load or read using following code snippets, where imagePath is the full path with image name from where the image can be read.
