The five most common vector formats are AI, EPS, PDF, and SVG. Because vector images are composed of geometric shapes, they can be edited and manipulated to change their appearance without becoming "blocky" or "pixelated." Additionally, because vector images are composed of mathematical formulas rather than pixels, they can be enlarged or reduced in size without losing any quality. Vector files are often used in graphic design for illustrations and logos, as well as in other applications where a high-resolution image is not needed. The five most common raster formats are JPEG, PNG, GIF, BMP, and TIFF.Ī vector image is a digital image that is composed of geometric shapes, such as points, lines, and curves. Because of the way they are stored, raster images can sometimes appear "blocky" or "pixelated" when they are enlarged. Raster images are often used in digital photography, as well as in web design and other applications where a high-resolution image is needed. Pixels are the smallest individual unit of a raster image, and each pixel contains colour information that is used to generate the final image. Frequently asked questions about raster filesĪ raster image is a digital image that is composed of an array of pixels.An introduction to resolution and compression for raster images.Benefits and downsides of raster images.The difference between a raster image and a vector image.We'll start with the basics and move on to more advanced concepts, so whether you're a beginner or an experienced user, there's something for everyone. In this guide, we will explore everything you need to know about these important graphics files. Raster images are made up of these coloured pixels arranged in a grid, and when viewed from afar, they create the image that you see. When you zoom in on a raster image, you’ll see the individual pixels that make up the image. Pixels are the smallest individual element of a raster image, and each one can be assigned a colour. Rasters are a type of image that is stored in a computer as an array of tiny squares, or pixels. If you’re reading this, there’s a good chance you work with digital images in some way – and if that’s the case, then you need to know about raster images.
