We strongly recommend to refer below post as a prerequisite of this.
- Image Processing in Java | Set 1 (Read and Write)
- Image Processing In Java | Set 2 (Get and set Pixels)
In this set we will be creating a random pixel image. For creating a random pixel image, we don’t need any input image We can create an image file and set its pixel values generated randomly.
- Set the dimension of new image file.
- Create a BufferedImage object to hold the image [ import java.awt.image.BufferedImage; ]. This object is used to store an image in RAM.
- Generate random number values for alpha, red, green and blue components.
- Set the randomly generated ARGB (Alpha, Red, Green and Blue) values.
- Repeat the steps 3 and 4 for each pixels of the image.
Implementation of the above algorithm:
Note : Code will not run on online ide since it writes image in drive.
