Q: A user opens a file containing an image of size 640 × 640; the color of each pixel is coded on 32 bits. It is assumed that this file is stored on disk in binary format "raw" uncompressed (no header, no end character line or end of file). The user edits the image as follows:
• User reduces its size to 286 × 286,
• User makes an image in 256 gray levels (coded 2 byte)
• User "overwrites" the original image by saving the edited picture with the same name.
a. What is the Original File Size?
b. What is the Compressed File Size?
c. What is the total number of blocks that were released?
