![]() ![]() Unlike vector images, raster files don’t maintain their resolution when resized. The disadvantages of raster files include: Raster files can open in a wide range of programmes and web browsers, making it easy to view, edit and share your images. This lets you enhance and tailor the image to your own needs. You have the power to individually alter each pixel when editing a raster graphic or photograph. The more pixels a file contains, the stronger the image quality. When displayed in the right dimensions, raster files can show off all the intricate details and colours found in high-resolution photos. If you’re thinking about using a raster file in your next project, make you sure you know the upsides and downsides before you start: That’s why illustrations or logos that need to be used across a variety of sizes often come in vector form.Īdvantages and disadvantages of raster files. ![]() Increasing the size of an image with too few pixels can cause pixelation, which isn’t usually desirable. However, each raster image is limited to its individual dimensions and number of pixels, which affects its size and resolution. With software like Adobe Photoshop, you can edit individual pixels within a raster file to change the appearance of a photograph. Most photos come in the raster file format, whether they’re print or digital. Raw photo files, which contain uncompressed image data taken directly from a camera’s sensors, are generally converted to raster files once edited.Īlso known as bitmap, raster files work best when you need to store and display high-quality photographs. This means that, compared to pixels, vectors don’t lose their resolution when resized. That’s why vector images are more commonly used for illustrations and logos - vectors are made up of mathematical formulas that can scale up or down infinitely. However, because their pixel number is fixed, raster images can become distorted or blurry when resized to fill a bigger or smaller space. Popular types of raster files include JPEG, PNG and GIF images. Digital photos and detailed graphics both come in raster form. There are two main types of digital image file - raster and vector. ![]()
