A vector line, for example, is made up of information that details the line’s attributes such as length, color, thickness, and angle. Vector files are composed of mathematical equations as opposed to colored pixels that are then taken by the computer and converted into visible graphical objects. One sure way to find out if an image is a raster type is to zoom in and see if there’s any pixelation that occurs. Typically, any PDF file that was produced from scanning a hard copy of a document, photo, or illustration will have a raster file in it. You probably know some of the more common raster file formats such as. Raster files, otherwise known as bitmap files, contain images that are made of clustered, colored, pixels. As for CAD formats, the best one for your needs depends on what you’re planning to use the output vector file for. There are a plethora of PDF file types, but our main focus will be the types of PDF files that can have raster objects, vector objects, and a mixture of both. The first step to figuring out what program to use is to look at two things – the type of PDF file we’re dealing with and the type of output we want to produce.
