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. Therefore, it is important that you save raster files at precisely the dimensions needed to eliminate possible complications. Vector images , alternatively, allow for more flexibility. Your company logo and brand graphics should be created as a vector and saved as a master file so you can use it with smaller items such as your business card and letterhead, but also on larger surfaces, such as your corporate jet.
Just be sure to save the new raster file in the exact dimensions needed. However, depending how a PDF is originally created, it can be either a vector or a raster file.
Whether you opt to flatten the layers of your file or choose to retain each one will determine the image type. To determine whether your raster images are a suitable resolution for a specific application, you need to check their pixel density. Units of measurement such as dots per inch DPI or pixels per inch PPI refer to the number of pixels in one inch of the image.
These measurements become important when you attempt to use raster images in specific places, such as on the web or in print publications. The web, historically, displays 72dpi 72 dots or pixels per inch — a relatively low pixel density however most modern displays are now much higher. Boxy SVG. Platforms: Web. Platforms: Web, Windows, Linux. LibreOffice Draw. An eps file is the gold standard for your logo files. It is a vector-based image, when exported from Adobe Illustrator, and is meant for print usage.
This means an eps file can be sized up or down without deteriorating the image quality. Vector files are much more flexible and rely on mathematical equations that generate files upon rescaling in order to allow a flawless image quality.
Vector files are most commonly used with graphic designers. Most commonly with the software from Adobe Illustrator, which specialises in vector work.
Vector graphics are made up by points or coordinates on a screen that are connected through lines and curves called paths. Vector graphics are widely used for creating logos, line art, 3D-like renderings, and animations, among other examples.
As DA01 pointed out, eps is merely a file wrapper. Simply saving as an eps does not mean something is vector. A sharp looking in-browser Illustrator alternative for stylish designs.
