number of pixels * 1.1
|
|
|
number of pixels wide * number of pixels high * number of bytes per pixel * 1.1
|
|
|
None of these is correct
|
Explanation:
Detailed explanation-1: -FILE SIZE is calculated by multiplying the surface area of a document (height x width) to be scanned by the bit depth and the dpi2. Because image file size is represented in bytes, which are made up of 8 bits, divide this figure by 8.
Detailed explanation-2: -The pixel dimensions may be determined by multiplying both the width and the height by the dpi. A digital camera will also have pixel dimensions, expressed as the number of pixels horizontally and vertically that define its resolution (e.g., 2, 048 by 3, 072).
Detailed explanation-3: -Column pixels (width ) X row pixels ( height ) / 1 Million. The size of an image can be defined by its pixel resolution.
