8/10/2023 0 Comments Raster vs bitmapThe Difference between Bitmaps and vectors This is because the mathematical formulae dictating how they are drawn are what is stored, not the colour information of the shapes that make up the image. The shapes that you see on the above menu are vectors. The Shapes dialogue in Microsoft Word shows a plethora of vector images that you can draw. Vector images, on the other hand, store mathematical formulae that draw lines and curves. An easy example of a vector image is the Shapes that you find in Microsoft Word: Bitmap images store the colour information of every individual pixel that makes up the above image. Those little tiny squares are what we refer to as pixels. Now, if we zoom really, really far in on the picture, we can see all the little tiny squares that make up the image: Let me show you a picture to better illustrate what I mean. What’s a pixel, you say? A pixel is a little tiny square that is filled with a colour. It stores the colour of each and every individual pixel that makes it up. So let’s talk about bitmaps and vectors.īitmap images, also known as raster images, store colour information. What we didn’t go into last week is what those two words beneath Types mean. In the last post, we looked at using sprites in Scratch. We looked at how to import pre-made sprites into your project from the in-built sprite library, and we very briefly acknowledged the fact that they were sorted into Categories, Themes and Types: What sets them apart is the way in which they store their information. Bitmaps and vectors are two different types of two-dimensional graphics.
