What is Pixel? How it helps representing shapes on screen?
The pixel, as previously stated, is the smallest addressable unit of an image. It is also referred as as pel or image element. Because real-world objects are continuous in nature, they have an endless number of samples. Only finite samples are taken into account when they are transformed into a picture and presented on the monitor screen. At the end of the day, the item on the computer screen is a collection of pixels. The monitor screen, like the digital image, is organized into a grid with n rows and m columns. Each cell on this grid is also known as a pixel. Each grey/black cell in represents one pixel.We can obtain a better idea of the pixel by zooming in on the image. In Figure each square represents one pixel. The pixel value for a grayscale image ranges from 0 to 255, where 0 represents black and 255 represents white. The grey colours with varied intensities are represented by the in-between range. Each pixel in a color image is a triplet of color (R, G, B) consisting of a proportion of red, green, and blue color. The final color of the pixel on the monitor screen is determined by the combination of these three components. Each component’s value ranges from 0 to 255, resulting in 255 x 255 x 255 = about 17 million distinct color tones.
pixels are smallest unit of any Image. combination of multiple pixels on screen makes a big image or shape.
