MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -For example, if we scale a raster image to enlarge it, without changing resolution, it will lose quality and look blurry or pixilated.

Detailed explanation-2: -Bitmap images In the image below, each pixel is represented as a single value that is different for each different colour. When you zoom in or enlarge a bitmap image, the pixels are stretched into larger blocks. That’s why bitmap images appear in poor quality when you enlarge them too much.

Detailed explanation-3: -Because bitmap images are made up of a set number of pixels that contain a set amount of information, when you enlarge the image, it doesn’t increase the number of pixels and looks stretched out and strange the larger it gets. This is the reason that when you try to enlarge a bitmap image, they become blurry.

Detailed explanation-4: -If you zoom in to a raster image you may start to see a lot of little tiny squares. Vector images are mathematical calculations from one point to another that form lines and shapes. If you zoom into a vector graphic it will always look the same. A raster image has a specific number of pixels.

Detailed explanation-5: -True vector graphics are comprised of line art, sometimes called wireframes, that are filled with color. Because vectors can be infinitely scaled without loss of quality, they’re excellent for logos, illustrations, engravings, etchings, product artwork, signage, and embroidery.
