![]() Raster images are used for photographs and high colored images in web and print, as they are capable of displaying various different colors in a single image and allow for color editing in the image. Hence, the logo will look the same on a business card as it will on a billboard. Vector images are often used for logos, letterheads, texts, and other designs, as it always the image to be resized without effecting its quality. A raster image, on the other hand, is visibly pixilated when enhanced. This is mainly due to the mathematical formulas, which allow the image to hold its form, as the formula dictates how the image is rendered. The advantage that vector images have over raster images is that vector images can be resized without any visible negative impacts. A vector image is limited, as an image has to be looped and closed off before it can be filled with color. Raster images are mainly used for high density images, or images with many different colors, as each pixel can have a different color, which can be overlapped for different colors and shapes. The data file for a vector image contains the points where the paths start and end, how much the paths curve, and the colors that either border or fill the paths. A vector image is made up of paths, each with a mathematical formula, also known as a vector, which tells the path how the each part of the image is shaped and what color it is bordered with or filled by. Examples of raster images include gif or jpeg. Raster images are more commonly called bitmap images. Vector images are typically generated using drawing or illustration programs, such as Adobe Illustrator.Ī raster images uses different colored pixels, which are arranged in a manner to display an image. Raster images are produced by digital image capture devices, such as digital scanners or digital cameras, or by pixel editing programs, i.e. The basic difference between raster and vector is that a raster image is made up of pixels, whereas a vector image is made up of paths. Raster and vector are two different ways to draw up computer graphics. An example of a vector-based design is the business card you give your clients whenever an opportunity arises.Key difference: A raster images uses different colored pixels, which are arranged in a manner to display an image. This would be impossible with a rasterized format. For instance, depending on the use, a business logo needs to be resized now and then. This is because such projects are less detailed and are often subject to regular changes. Vector images are a more common sight in line-art applications such as logo designs. Other than, you also need not worry about extra space because even when enlarged, a vector-image uses relatively less space. It simply means that your image will retain its quality regardless of how you enlarge it. Nonetheless, worry not as this does not mean you'll be dealing with calculus during editing. That is why you'll sometimes hear someone refer to the lines, shapes, and curves of a vector-based graphic as vertices and paths. The resolution of vector images is often dictated by mathematical equations. Vector-based data is often made up of various lines, shapes, and curves. This explains why they are a preferred option when it comes to web applications. While on the one hand, it's a downside, on the other hand, the pixel-based structure of a rasterized image is also an advantage as it can be scaled down to fit applications that require small-detailed images. Thus, if space is an issue for you, it would be wise to downsize. You will, nonetheless, need a bigger disk as more pixels in an image mean that it'll use more disk space. Therefore, to ensure your raster-based images are of the best quality possible, use more pixels. Thus, the more pixels present per inch(PPI), the better the resolution and vice versa. The resolution of a raster image is however dictated by the number of pixels in every inch. When you zoom in or enlarge, you're practically forcing your device to create non-existent pixels, hence the pixelation. While raster graphics are popular, it's vital to note that due to their pixel-based structure, they tend to be grainy or blurry when resized or enlarged. Some of the most common raster formats include: In most cases, these pixels are square-shaped, regularly spaced, and each one carries a specific shade, which contributes to the vivid and detailed appearance of the image. Also known as a bitmap, a raster image is a graphic made up of thousands or even millions of colored dots known as pixels. If you use the internet every day, then you encounter raster graphics daily.
