![]() Image formats like jpeg and gif are common compressed image formats. We use algorithms that compress images to help reduce these file sizes. As an example, a 640 x 480 image requires information to be stored for 307,200 pixels, while a 3072 x 2048 image (from a 6.3 Megapixel digital camera) needs to store information for a whopping 6,291,456 pixels. The larger the image, the more disk space the image file will take up. This means a large file needs a large bitmap. Raster images use bit maps to store information. Because the mathematical formula recalibrates to any size, you can scale a vector image up or down without affecting its quality.Ī bit technical, right? So, let’s look at that in a bit more detail and with an example or two. A vector file’s mathematical formulas capture shape, border, and fill colour to build an image. Vector files use mathematical equations, lines and curves with fixed points on a grid to produce an image. The file size an image also depends on the file type and compression used (for example, JPEG, GIF, or PNG). ![]() The more pixels an image has, the higher quality it will be, and vice versa. Raster files are images built from pixels - tiny colour squares that, in great quantity, can form highly detailed images such as photographs. So, what is the difference and why does it matter?Ī great explanation of the difference between Vector and Raster images can be seen on the Adobe website (See our Reading & Resources section at the end for the web link). There are two popular ways of creating an image file on a computer one is the very common Raster method, also known as a bitmap the other is a Vector file. Probably the first thing that we would need to know is the two different ways images are put together and what that means for laser cutters. This month, we will be working with popular laser cutter software LightBurn creating a simple Tangram project learning about some of the Functions available in LightBurn and starting to set up our project ready for actual cutting on the Laser. How to use LightBurn laser cutter software, and use a laser cutter to create a simple Tangram project.
