(a) Describe how a black and white image could be represented in binary. [3] Using the numbers 0 and 1 (b) How many bits per pixel would be required for an image with a palette of 256 possible colours? [1] 8 State two factors that affect the file size of a bitmap image. [2] Calculate the file size of each of the following images. [2] (a) A 256 colour icon with dimensions of 50 x 50 pixels. (b) A 16 colour icon with dimensions of 100 x 100 pixels. Additional metadata data is stored alongside the binary colour values for each pixel. Give two examples of metadata. [2]
