In this instructable I have provided a wide collection of tutorial videos that show how to use two different free applications to create either raster or vector images. When it comes to photographs and certain shaded graphics however, raster images are the better option. Typically in graphic design vector images are more widely used. Even 3D printers read 3-dimensional vector images (.stl files). Common file formats for vector images are. Any image that is produced on a CNC machine like a mill, router, vinyl cutter, or laser engraver is a vector image. Vector images are used for countless applications because of their versatility. A company would make their logo in a vector format because they may want it to be printed small on a hat one day and huge on a billboard the next. When a vector image is enlarged a computer recalculates the image so no quality is lost as is with raster pixel images. Because of this, vector images are infinitely scalable. When a computer looks at a vector image it sees equations that make up the image's structure. When we look at a vector image we see a graphic or clipart. Vector Images are those made up of points, lines, and curves. When a raster image is enlarged the pixels are enlarged and the image will become blurry, blocky, or pixelated. The more pixels, the higher the resolution or quality. Because they are constructed of pixels the quality of raster images are defined by the number of pixels in an image. All images created using a camera are raster images, those being constructed of pixels. In industry raster images are used on documents, posters, advertisements, and magazines. Raster images are the more common form of graphics and ones that you are probably used to working with. Raster Images are those made up of a grid or dot matrix of color or pixels. Images, one of the more common forms of media, comes in two different types. Your results should be visually arresting, professional in appearance and entirely dictated by your own tastes.In today's world we are surrounded by media. ![]() Simply de-select the ‘Anti-Alias’ option and click ‘OK’ to complete the process.įor the Raster Effect method, select ‘Rasterize’ from the ‘Effects’ option on the toolbar, select your options as you would for the permanent option and make alterations using the ‘Appearance’ panel, before saving. You can then select Color Mode based on your Printer Preferences and resolution and background options. For the former, click ‘Options’ in the toolbar, followed by ‘Rasterize’. You will then be given the option to either permanently rasterize the image or simply give the appearance of a pixel-based image, known as a ‘Raster Effect’ option. For multiple images, click the ‘Control’ button as you select the images. While text can also be rasterized in order to store it in bitmap files, we’ll look here at how to rasterize images in Illustrator.Īccess the best video tips, design hacks, and deals straight to your inbox.įirst, open the Illustrator app and open the document containing the image you want to rasterize. While there are numerous ways to rasterize an image, the simplest and most straightforward method is by using the Illustrator tool on the Adobe program, Photoshop. This will give you an affordable way of experimenting with textures and graphics, whilst learning how to convert vector images to raster images. ![]() The image can be refined to the choice of the user and the rasterization process provides a speedy way of creating an image that can then be altered via shading, for example, on programs such as Photoshop.īefore attempting to rasterize a favorite photo or the like, it’s worth visiting sites such as Storyblocks, where you can download an unlimited number of royalty-free graphics and stock images via a subscription service. ![]() This makes the image suitable for output on a video display or printer, and is the most popular method of producing 3D graphics on a computer. The term refers to the task of converting an image constructed of vector graphics (shapes) into one based on pixels and dots. There are a few questions to address before we look at how to go about rasterizing an image, however, the first two being: what is rasterization and why is it useful? Take a look here for our tutorial on how to vectorize an image! People who ordinarily wouldn’t touch a keyboard and mouse would get a lot out of this task. It isn’t just graphic designers, artists, or those who work in front of a computer screen all day that can reap the benefits of image rasterization.
