What is a vector EPS or PDF image file?
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.

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. Instead of sectioning off a large region of computer memory and mapping that to the display device, vector display devices use a variable number of lines to create images—hence the term "vector graphics. There was a video game console that used vector graphics called Vectrex as well as various arcade games like Asteroids , Space Wars and many cinematronics titles such as Rip-Off , and Tail Gunner using vector monitors. Modern vector graphics displays can sometimes be found at laser light shows , where two fast-moving X-Y mirrors position the beam to rapidly draw shapes and text as straight and curved strokes on a screen. Vector graphics can be created in a form using a pen plotter , a special type of printer that uses a series of ballpoint and felt-tip pens on a servo-driven mount that moves horizontally across the paper, with the plotter moving the paper back and forth through its paper path for vertical movement.

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. It would be great if I could easily convert a PDF so that all of its vector images were rasterized.
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.
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 is important since the two file types are converted differently.
Raster vs vector graphics images
Often our clients will ask us to print some large-scale artwork, such as a flag, banner or a billboard. To ensure we can produce the best results, we'll need your logo in best format you have it in - the highest resolution available. That would be a scalable vector format usually an. A logo in vector format can be scaled infinitely and never lose quality. The example below shows the difference between a vector PDF image right and a Bitmap JPG image left when the graphic is zoomed or enlarged. Why is that? These coordinates are relative to other coordinates.
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?
Raster & vector
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.
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.
