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. Note: you can use vector programs for any contest on 99designs. This is because vector graphics are easily manipulated and can be sized and resized limitlessly, without a loss in quality. You can use raster programs when designing a website, app, icon, banner ad, or any other design intended for electronic use. When to use vector graphics: Vector graphics are the preferred file formats for logo design, typesetting for print, cut designs, large format printing and screen printing T-shirts, for instance. 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. Scalable Vector Graphics, or SVG, is a vector graphics format that is comprised of shapes, lines, curves, colors, and text. Raster images are made up of a set grid of dots called pixels, where each pixel is assigned a color value. Given that all display mediums (screen, print) only show images as. In contrast to pixel graphics, the display size of vector graphics has no effect on memory requirements. Raster graphics store visual information as a two-dimensional map of pixels, also known as a bitmap. By comparison, a circle depicted through a pixel graphic will display ‘jaggies’ (stair-like lines where there should be smooth curves instead) or an aliasing effect. The biggest advantage of raster images is their richness in details and colour gradations and therefore high quality. How Do Raster Graphics Work The file storage method is one of the main differences between raster and vector images. 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. There are several differences between raster and vector formats, from storing data within the files to ideal use cases. If the square is vector-based, it’s made of just four points. If that square is raster-based, it’s made of thousands of pixels. In reality, the two file formats tend to serve different purposes. The easiest way to think of it is to picture a square. Vectors are scalable, and rasters are not - is the short answer. Vector programs include Adobe Illustrator, CorelDRAW, and Inkscape. The main difference between vector graphics and raster graphics is that raster graphics are made up of pixels. Vector images are made up of points, lines, and curves that can be infinitely scaled without any loss in image quality.
