![]() Higher-quality images will render better but also take up far more storage space. jpg (Joint Photographics Expert Group)Īlthough the image files will all display pixels, the display settings will vary across file sizes. You can save raster files in the following formats: While raster images are effective for photography, it is not as effective for designing logos for example as the sizing capabilities are limited to your pixel count. Raster images work best for photography and imagery rather than design work because they cannot be scaled the way vector images can and often become distorted when blown up into massive dimensions. Raster images are most commonly found in photography and digital tools, and to make any edits or changes, you’ll need a raster-based program such as Adobe Photoshop. One advantage of raster images is their ability to show subtle color gradations and complex compositions. You’re able to clearly see each pixel resulting in low quality Lower pixel counts are obvious when zooming into the image. Raster images are commonly made from photo scans or digital camera captures and are best suited for non-line art images.Ī higher number of pixels means a higher quality image. Raster graphics or bitmap images are digital images consisting of tiny rectangular dots/pixels in a grid formation to represent an image. Now that we’ve established some key terms, we’ll look at what a Vector image is. Images on screens are essentially made up of small squares containing different color codes.īitmap: A bitmap is made up of pixels in a grid formation, and collectively makes up an image or picture. Pixel: A pixel is the smallest element of an image on a screen. You’ll often come across the terms ‘pixel’ and ‘bitmap’ in the design process. pdf.We’ll first look at some important terms you’ll need to remember throughout the process. Used when graphics are required in different scales, but always in the highest quality.Ĭommon file formats.Vector graphics are particularly suitable for displaying geometric designs and figures, logos, icons, pictograms, technical illustrations, product illustrations, fonts and the creation of layouts.The more extensive a vector graphic, the more time this process takes. To depict a vector graphic, the image must first be rendered.For high-quality results appropriate editing programs as well as special knowledge and skills are necessary.Detailed images can be difficult to display as vector graphics due to the many different shapes and colours.Converting a vector graphic into a raster image is much easier than the other way around.Changes such as size, colour, position are easily possible at any time. can be easily, flexible and precisely edited and adjusted. The characteristics of lines, curves, areas etc.Vector graphics can be upsized or downsized as desired, their high quality is maintained. The main advantage is the continuous and lossless scalability. ![]() These parameters define exactly the objects that make up an image or graphic. starting point, length, direction, colour etc. The shapes are described by certain parameters, e.g. Vector graphics consist of geometric shapes such as lines, curves, circles, and polygons. online monitors, digital cameras.Ĭommon file formats.
