Typical formats for vector image files include types you might not be that familiar with, such as SVG and EPS. It is important to note that although vector images do give you greater control over some kinds of designs, they cannot be used in any practical way for photographs or photo-realistic images, which are better suited for bitmaps. For instance, you may utilize a logo on a billboard or something as little as a business card due to the flexibility of this re-sizing. Because of this, vector images are said to be “resolution-independent”. The quality of the image won’t be affected by changing, editing, or resizing specific image elements (or paths). These types of images are made up solely of shapes like rectangles, circles, curves, and lines, and only vector design programs like Adobe Illustrator are used to create these lines and curves. Vectors are drawn, then filled or stroked with color to make a vector image. They are therefore perfect for logos, icons, and graphics. Utilizing this method designers can scale illustrations as simple as a form or as intricate as a full-fledged illustration while creating vector graphics. These calculations, also known as Bézier curves, provide directions on where to find each component needed to produce the desired part. Instead of using pixels to depict images, vector images use geometrical calculations (mathematical equations) based on paths. The end product of these photographs being uploaded online is a raster image. The image is saved as pixel data when you take a picture with a phone or camera. A greater file size and more data will be present in an illustration with a higher DPI (dots per inch) or PPI (pixels per inch), which might only be problematic if there are storage or upload size restrictions on images.ĭigital and photographic applications use raster images. One drawback for many users is that raster images can have enormous file sizes due to the high pixel density, but it’s of small concern when you are trying to get the best possible imaging. You are probably familiar with some of the types of bitmap files as they include JPEG, BMP, GIF, and PNG. Since the quality or sharpness of the image depends on the resolution, this type of process is frequently referred to as resolution-dependent. A bitmap image loses quality when you zoom closer because you can see the individual pixels. The color code and location of every pixel are mapped to one another to create a picture. Both have advantages and disadvantages, making one more appropriate for printing photographs and the other more appropriate for graphics or logos.īitmap, also known as raster images, which are made up of tiny color blocks called pixels arranged in rows and columns, are the most popular types of image files. Vectors are shapes and colors created using mathematical formulas, while bitmaps are blocks of colors arranged in a grid style. The way that bitmaps and vector objects are put together is the primary distinction between them. Both of these work very well across most design platforms, but in this piece we’ll go over the differences between them – and when you should be aware of the difference. As you start designing more, you’ll note the use of terms “Vector” and “Raster” (or “bitmap”). However, some of the processes, methods and formats are specific to certain uses. But with new methods come more options, and in the world of graphic design there are two main ways to go about getting your end result to page. With advanced in technology, one might assume this would make things easier. With almost any creative endeavor, there is often more than one accepted way to go about getting to an end result.
