MediaTracker was a solution for the hard to understand Image Observers. MediaTracker can check the status of a number of images in parallel. It uses image Ids to keep track of images, and the same id can be used for multiple images. MemoryImageSource class is a class that constructs a new image from an array of data. The MemoryImageSource object is constructed out of an array of integers specified by pixels in default RGB color mode.
Pixels have an alpha, red, green, and blue element, where alpha is the transparency level.
It allows a user to remove sections of an image, thus shrinking the size of the image. Explain the functionality of the ImageFilterDemo. It uses buttons associated with each filter along with an image to demonstrate the effects of each filter. The output pixel has the difference of the center pixel and the average added to it thus enhancing the appearance of the image.
