The blockSize parameter specifies how big the mosaic block is (e.g. blockSize = 4 would mean the mosaic block size is 4 pixels by 4 pixels). The mosaic method should replace each block of pixels in the image (e.g. if blockSize = 4, each block of 4 by 4 pixels) with the average color value of the pixels in that bl k L k h Pi lMifiliPh hf lfhhiblock. Look at the Pixelate->Mosaic filter in Photoshop for an example of what this image operation does. Demonstrate your new class by drawing an image with several different block sizes. Include your example images with your submission.A3-02: Write a small app that demonstrates kinetic text. Your app should allow the user to type something and the text moves around in some way while they type. For example, the user might type text on a line, but slowly the words or letters start drifting apart or perhaps the line starts bending or the words and letters flutter
