Have you wondered why some pictures show jaggies on the edges when they are resized larger. Or why some pictures don’t show jaggies when enlarged? Those jaggies have more to do with the type of graphics you’re resizing, and broadly speaking, there are two types of computer graphics: bitmaps and vector graphics. If you use graphics often, understanding these two formats, their differences, and how they are created is essential. To put in a nutshell, bitmap graphics get the jaggies when they are resized. And vector graphics can be resized to any extent without the pixelated jaggies.
