Some application domains, such as geographic information systems (GIS) and graphic design, use both vector and raster graphics at times, depending on purpose. Thus, it is the preferred model for domains such as engineering, architecture, surveying, 3D rendering, and typography, but is entirely inappropriate for applications such as photography and remote sensing, where raster is more effective and efficient. While vector hardware has largely disappeared in favor of raster-based monitors and printers, vector data and software continues to be widely used, especially when a high degree of geometric precision is required, and when complex information can be decomposed into simple geometric primitives. Vector graphics is an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations. The associated mechanisms may include vector display and printing hardware, vector data models and file formats, as well as the software based on these data models (especially graphic design software, computer-aided design, and geographic information systems). Vector graphics is a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. Example showing comparison of vector graphics and raster graphics upon magnification For other uses, see Vector graphics (disambiguation). It just takes a little bit of practice.This article is about computer illustration. Microsoft may have gotten rid of clip art for PowerPoint, but there’s no reason why you can’t edit free vector images and get what you need for your presentations and elearning courses. I also add a few extra production tips.Ĭlick here to watch the video tutorial at YouTube. Here’s a video tutorial that shows how to edit free vector images in PowerPoint. You’ll notice that the original colors were softer and the lines a bit thinner. Compare the before and after images below. In that case it’s probably not worth messing with it.Īlso, some of the colors and shapes may change, too. The image below shows the before and after of an ungrouped file in PowerPoint. Ungrouping that image creates about 8500 individual shapes. However, it does break down if the shapes are made of gradients and not solid colors. Potential Issues If You Edit Free Vector Imagesįor the most part, ungrouping. I also save the PowerPoint file in case I want to make additional changes down the road. Right-click and select “Save As Picture.” I usually save as.
