3/19/2023 0 Comments Raster images![]() ![]() For high-accuracy, scalable drawings, vectors are the obvious choice, but for complex, textured images or simple website inserts, raster images are the better choice. When choosing between vectors and rasters, you need to decide what you are looking to create. Learn more about importing and exporting files in BricsCAD → Which is better? However, BricsCAD also gives you the option to export to other formats, both raster and vector! Plus, the Communicator for BricsCAD, offers even more import and export options. This is the default file type for all drawings in BricsCAD. Less options for colors, textures and shading Bottom right: zoomed-in to same detail on the raster screenshot.

Overall, as compared to vector graphics, raster graphics are less economical, slower to display and print, less versatile and more unwieldy to work with. Vector images are more "specialist" and are better for technical drawings, images that need to be scaled, high accuracy plans, logo design, exporting to machines such as CNC, etc. Raster images are more "typical" and are used primarily for graphical work: photography, print, website images, digital artwork, etc. Vectors are scalable and rasters are not - is the short answer. In reality, the two different file formats tend to serve different purposes. What is the difference between raster and vector? That means any image will be around ¼ the size when printed. The best resolution for screen/digital images is typically 72dpi the best resolution for print is typically 300, although sometimes 150 is "acceptable". The resolution of a raster image is defined by dpi (dot per inch). Here the BricsCAD logo has been scaled in raster form, notice that the image quality is greatly reduced. This is exactly how a raster image works, but with much smaller squares. Think about old school video game graphics. That's because it is essentially made from a set of colored squares. If you make a raster larger, it will become "pixelated" and lose quality. Most computer images are stored in raster graphics formats or compressed variations, including GIF, JPEG, and PNG, which are popular on the World Wide Web. Vector file types:Ī raster image is a specific size. Here the BricsCAD logo has been scaled in vector form, notice that the image quality stays the same. You are simply telling the computer to draw a line between different points. If you draw a square of 1cm by 1cm and you scale it by 100 you will have a box that is 100cm by 100cm and it will look exactly the same. That means you can change the size to as large or small as you want and the image will remain the same quality. Overall the individual pixels together create the picture you see as an image on your screen. These are created one-for-one from the sensor photositeson the image sensor of a camera or scanner. What is a vector image? What is a raster image and what's the difference between raster and vector? Keep reading to find out!Ī vector image is scaleable. Raster images Raster images are formed from an array of pixels. ![]()
