For more information on vectors and rasters images, see our blog post, The difference between vector and raster images. Vector images are mathematical calculations from one point to another that form lines and shapes.

However, you cannot use raster programs for logo contests. At a certain point, when the raster image is enlarged enough, the edges become ragged, and it appears pixelated - i.e., when the pixels become visible. Raster graphics are made up of a fixed number of pixels, which makes them less scalable than vector graphics. Note: you can use vector programs for any contest on 99designs. Unlike raster images, vector images are made up mathematically defined geometric shapes like lines, shapes and curves, with additional attributes like color and. A raster graphics image maps bits directly to a display space, also called a bitmap. You can use raster programs when designing a website, app, icon, banner ad, or any other design intended for electronic use. Raster programs include Adobe Photoshop and GIMP.

When you change the size of a raster image, you shrink or stretch the pixels themselves, which can result in a significant loss of clarity and produce very blurry images. Unlike a vector image, raster images are resolution dependent. A raster image is simpler to understand, but takes up much more memory to work with. Raster images are made up of a set grid of dots called pixels, where each pixel is assigned a color value. Raster and vector graphics are two ways of representing an image of some sort using the native language of 1s and 0s employed by computers. You must use a vector program when designing a logo, and we suggest that you use vector programs for any other print design contest as well. Vector programs include Adobe Illustrator, CorelDRAW, and Inkscape. A raster is a string of numbers (brightness data) which have a one to one correspondence to a 2-d grid. It is metaphorically similar to a musical score. Vector images are made up of points, lines, and curves that can be infinitely scaled without any loss in image quality. A vector is a descriptive language that allows a person or computer to recreate the image by following a set of steps.
