##### Aspect ratio (Ratio width and height):

:

DPI is an abbreviation for “Dots Per Inch” and stands for the number of dots (pixels) per inch (image resolution).

The measure of the resolution of a monitor, printer, scanner, and other devices is determined by the number of DPI dots per inch. Such a measure is used to know the resolution of flat media

The smallest part of a digital image, a pixel, is a square or non-square image element, like a piece of a puzzle. A megapixel (MP) contains 1,000,000 pixels, and the number of megapixels offered by a camera system is the amount of information it can transfer into a digital photo or video.
