![]() ![]() For more information on vectors and rasters images, see our blog post, The difference between vector and raster images. However, you cannot use raster programs for logo contests. Vector files, made up of points and lines to create paths, can be scaled up. Vector images are mathematical calculations from one point to another that form lines and shapes. What is the difference between vector and raster files for graphics Vector files. If you zoom in to a raster image you may start to see a lot of little tiny squares. Note: you can use vector programs for any contest on 99designs. A pixel is a single point or the smallest single element in a display device. The preserved data is the result of a clip. To clip data, you need points, lines, or polygons as input and a polygon as the clipping extent. And carving out vectors and rasters is one of the most common operations in GIS. Vectors prioritize crisp, mathematically precise lines which can make it difficult to replicate an imperfect, hand-drawn look. If you can picture a cookie cutter, this is like using the clip tool. This can result in a more flat, cartoonish style. Vectors do not display complex color gradients, textures or shading. You can use raster programs when designing a website, app, icon, banner ad, or any other design intended for electronic use. If youve been using Photoshop, Illustrator or InDesign for any length of time youll, no doubt, have heard the terms vectors and rasters (or pixels). Vectors tend to have smaller file sizes than rasters. Raster programs include Adobe Photoshop and GIMP. We will add a custom color, making the plot grey. ![]() If the image becomes blurred or pixelated, it’s most likely a raster file. A hillshade is a raster that maps the shadows and texture that you would see from above when viewing terrain. An easy way to tell if an image is raster or vector is to increase its size. 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. We can layer a raster on top of a hillshade raster for the same area, and use a transparency factor to create a 3-dimensional shaded effect. Unlike a vector image, raster images are resolution dependent. Raster images are made up of a set grid of dots called pixels, where each pixel is assigned a color value. 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. Vector images are made up of points, lines, and curves that can be infinitely scaled without any loss in image quality.
