Much of the code to do this is given at the bottom of the page (Imp.java). Please do this in Java.

Below is the Imp.java to be used to write the code:

  Start Download Imp. java and create a new project with the stubbed code About the Software Imp is the shell of a image processing application. It will allow you to open an image, jp or (I think, but don't really remember) .gif file g Once an image is open it breaks downeach pixel of the image into first a single dimensional amay, and then converts that into a 2D array of pixels Each pixel in the 2D array, which is callcd "pixels in the array is an integer valuc, a large intcgcr valuc that is of no usc to you as just an int. Embedded into each integer value is a one byte value for red, green, blue and a alpha channel (transparency). In order to get the values of a pixel at some random location, let's say X 100, Y 200, you would request an int from the array: int currentPixcl picture[YIDX]: Mnotice Y is first, Y is the height of the image, X is the width. Then in order to breakdown that pixel to it's red, green, blue, alpha channel you need to set up an amay and send that int to getPixelArray method like this int rgbArrayn new intl4 rgbo Amay getPixelArray (currentPixel) Now the rgbArray has the value for Red in rgbArray[1, Green in rgbArray[2], and Blue in rgbAmay 121. rgbAmayIOI is transparency, don't mess with this for now. it should always come back as 255. If you switch it o 0 your pixel becomes transparent Here is how the integer gets broken down to 4 bytes, it's bit twiddling private int O getPixelArray (int pixel) int templ new int 4] templ0] (pixel, 24) & 0xff. pixel 16) & 0xff emp temp12] (pixel 8) & 0xff; empl3 (pixel & 0xff. return temp Then you get a rgbArray back from this method, do tests, manipulate based on values, and when you're ready to put it back to an int you can put back into an array that can be drawn to the screen you call this method private int getPixels (int rgbu) int alpha 0. 24 (rgbli
