MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -1 Pixel Coordinates. A digital image is made up of rows and columns of pixels. A pixel in such an image can be specified by saying which column and which row contains it. In terms of coordinates, a pixel can be identified by a pair of integers giving the column number and the row number.

Detailed explanation-2: -Pixels are arranged in a 2-dimensional grid, represented using squares. Each pixel is a sample of an original image, where more samples typically provide more-accurate representations of the original.

Detailed explanation-3: -That means there are 1680 pixels on each row and there are 1050 rows of pixels. On any given monitor, changing screen resolution changes the number and size of pixels used to display objects such as icons, text, buttons, and images.

Detailed explanation-4: -Each pixel is represented by a number of bits and programs can specify where each pixel is placed on the screen and what colour it is going to be. An image represented this way is called a Bitmap . The following 1-bit image shows how pixels are made up of binary code.

Detailed explanation-5: -A raster image is a two-dimensional grid of pixels arranged into rows and columns. As such, it has a natural coordinate system in which each pixel corresponds to a pair of integers giving the number of the row and the number of the column that contain the pixel.
