![]() Now Vectors (CAD Software) : Vectors are a result of mathematical calculations, lines and curves hat are generated on the screen from one point to another and because of this vector will never get distort after an stretch/zoom operation, Because vector graphics are not made of pixels, the images can be scaled to be very large without losing quality. Like a gradient/transition from one colour to the other. That happened because the computer will try to FILL the gap between the 2 pixels with other pixels that may be are in the same tone of colours If you stretch the image the image will distort Why? Supouse there is to pixels 1 red the other blue, before you stretch the image they are one close to the other, after you stretch the image you will notice that between the 2 pixels now are 5 pixels (depending on the new size of the image of course), and that is the origin of the distortion of any image. Lets analyse something: Lets say you scan a picture of the size (in inches) 5x7 in you put inside photoshop with a canvas 8x11 inches big. ![]() ![]() There 2 fundamental definitions when you work images and CAD software: The first thing is that images are a result of a computational process that, as a result, get every single bit of information that comprises the image get to store as small dots, pixels. ![]()
