Oct 14 reflection

  • How many bits (or bytes) are required to encode an image that is 25 pixels wide and 50 pixels tall, if you encode it with 24 bits per pixel?
    • 3753 Bytes or 30,024 bits
  • Imagine that you have an image that is too dark or too bright. Describe how you would alter the RGB settings to brighten or darken it. Give an example.
    • Change the RGB code from something like (200, 188, 210) to the same ratio but half the numbers to make it darker (100, 144, 110).
  • If you had to send your favicon using the sending bits widget, it would probably take a long time. Could you compress your image? How? Describe in broad strokes the kinds of things you could do.
  • Yes I could make a character represent each color pixel and send all the blue pixels as one character and such. Then send the dictionary also. This works better if you use one color multiple times.
