3 Easy Ways to Spot the Difference Between Vector and Raster PDF
Vector vs. Which one is best? It has a lot to do with how the image will be used. When creating high-resolution graphics, you do want the best files for your project. Use this simple guide to help you choose the right files to send. Have a question? Ask us here.
When starting off a project, one of the first things we request from the client is a vector file of their logo. As a marketer, understanding the importance and role of different image file types is essential to ensuring your brand is properly represented and to better communicate with designers, developers and printers. We can start making sense of the issue by clarifying the difference between the two major image types — raster and vector. Raster images use many colored pixels or individual building blocks to form a complete image. Almost all of the photos found on the web and in print catalogs are raster images. This is why altered photos may appear pixilated or low resolution.
How to determine whether your PDF is raster- or vector-based, and how this affects the ability to snap to an object or select text. Some PDFs contain more information than others, even though they seem indistinguishable at first. The page may appear to contain lines and characters, but the underlying elements that represent them in the PDF may not be vector lines and text elements, which are needed to snap to content and search and select text. A raster image is created from a series of square dots called pixels. One example of a raster PDF is a file created from scanning a paper. This means that a scanned or raster PDF only contains a grid of dots that represent lines and text; it does not actually contain lines or text that a computer can recognize.
Each color pixel contributes to the overall image. Raster images might be compared to pointillist paintings, which are composed with a series of individually-colored dots of paint. Each paint dot in a pointillist painting might represent a single pixel in a raster image. The pixels in a raster image work in the same manner, which provides for rich details and pixel-by-pixel editing. Raster images are capable of rendering complex, multi-colored visuals, including soft color gradients. Digital cameras create raster images, and all the photographs you see in print and online are raster images.
Computer graphics can be created as either raster or vector images. Raster graphics are bitmaps. A bitmap is a grid of individual pixels that collectively compose an image. Raster graphics render images as a collection of countless tiny squares. Each square, or pixel, is coded in a specific hue or shade. Individually, these pixels are worthless. Raster graphics are best used for non-line art images; specifically digitized photographs, scanned artwork or detailed graphics.
different image file formats for Raster graphics and Vector graphics which will original artwork is a vector file, the PDF will be vector art; if the original artwork is.
Vector graphics are computer graphics images that are defined in terms of points on a Cartesian plane , which are connected by lines and curves to form polygons and other shapes. Vector graphics have the unique advantage over raster graphics in that the points, lines, and curves may be scaled up or down to any resolution with no aliasing. The points determine the direction of the vector path ; each path may have various properties including values for stroke color, shape, curve, thickness, and fill.
Today we are going to explain the differences between raster graphics and vector graphics for our general public. Raster graphics images or bitmaps are based on the elementary concept of the pixel. Raster images are made of pixels ordered in arrays or matrices , each pixel having its own coordinates and color, similar to how a mosaic is made out of small pieces of colored glass. Hence, the greater the quality resolution , the bigger the file size. Vector graphics , on the other hand, do not store image information as pixels.

In other words, I want to generate a PDF with the exact same un-rasterized text but with each vector image replaced with a rasterized version. However, while raster images seem to make it through the conversion process fine, vector images get horribly mangled.
Often our clients will ask us to print some large-scale artwork, such as a flag, banner or a billboard.
