We say vector graphics have “infinite” resolution because they never lose their quality, even if you zoom in on them indefinitely. Vector graphics have a very specific set of advantages that make them unique and powerful.

This, in a nutshell, is how vector software renders drawings. Remember those connect-the-dots drawings from our childhood? Vector graphics work like connect-the-dots drawings If we know the position of at least two points on a plane, we are able to draw a line between those two points. Well, vector graphics are basically coordinates on a plane. Just upload your PDF, adjust the look and then simply download.The mathematical grounds for vector graphics date back to at least the 1800s with Euclidean vectors, which are able to describe two points on a plane by determining their location and direction.

So, let’s start converting PDF colors to grayscale or black and white. This way the integrity of data is kept largely intact… unless you want to print on the side of a building! One trick to see if the resolution is significant is to zoom in close on an element and see if the quality is sufficient for your use case. To keep those lines and images sharp, SuperTool processes in high resolution and creates large files. They read and process in a combination of raster and vector, but most often output in raster format. The PDF applications at SuperTool can work with both raster and vector PDFs. If graphics contain only text and simple graphics like bar charts and solid blocks of color, vector formats have not just the advantage of smaller file size, but also can be scaled up to larger sizes well. This will come at a “cost” of image size, but is usually well worth it. For complicated color images, which includes most real photos, a raster graphic will more accurately represent the colors. The two graphics could look similar, but would have the color data stored separately. Vector graphics have the color data stored in “meta-data.” Imagine a graphic that fades from red to green. Raster graphics embed the color within each pixel.
The same file containing “Great” as a vector could be just a few kilobytes of even less. It would be possible to represent “Great” in raster format inside a PDF that would look clean and sharp, but this file would likely be very large (e.g., many hundreds of megabytes). This depends, of course, on the quality and resolution of the printer, but the same thing could be said for a very large computer screen.īut if you tried to do the same thing with a (normal quality) PDF with a raster image then the edges of the lines in the letters would look ragged, torn, or blurry if they were printed on the side of a building. For example, let’s say you have a PDF that contains one word: “Great.” If that PDF contains the text as a vector format, you could print it out filling the side of the Empire State building and it could look clean and sharp. The major difference from the standpoint of PDF users is that a PDF containing vector-based components can be scaled nearly infinitely and maintain graphic integrity.
Indeed, a PDF that has both formats side by side can be nearly indistinguishable both on a computer screen and even when printed out on paper. You can’t always spot the difference quickly. So a PDF is never really “raster” or “vector” but rather is a container file type that could contain one or more forms for representing items visually.įrom the perspective of your eyes, two images that look almost exactly the same can be vector and raster. Often they include images and text, both of which can either be in raster or vector formats. PDFs are digital files that contain various sorts of data.
