Vector or contour (from English. speech outlining) is usually referred to as the formats are building an image only by line segments (vectors). Recently, however, the term “vector” applies to all formats, operating with geometrical figures, in contrast to raster formats that describe the image on the points.

Vector Graphics (another name – Geometric Modeling) – is the use of geometrical primitives such as points, lines, splines and polygons to represent images in computer graphics. The term is used as opposed to raster graphics, which represents an image as a matrix of pixels (dots).

Initially, the human eye perceives the image like a bitmap image. The image is projected onto the retina, consisting of separate cells respond to light. Next, the system of eye-brain recognizes the image individual objects, geometric shapes, which was easier to handle and store.

You’ve probably already noticed that every file has a special extension that indicates ownership of the file to a specific format and program that works with this format. Extension is appended to the file name and separate points, for example Imya_fayla.rasshirenie. The Windows operating system standard extensions are hidden from the eyes of novice computer users. Understand about the file format can be on its icon (icon), it is not always the best solution, but you can toggle the display of file extensions manually. To do this, go to My Computer and click Tools – Folder Options – View and Uncheck Hide extensions for known file types. Keep in mind that if you do not have a menu or setting is not saved – your computer may be infected with a virus, which prohibits the display of hidden files and extensions (such is common virus Autorun). So, what we can tell you these few letters, called extension, and which one belongs to which format?

We will not consider in this paper a list of all graphics formats, as it will take quite a lot of time. We will tell you about the most common of them will show the differences between image formats, and explain what format for which you want to use.

All existing image formats can be divided into vector and raster. What is a bitmap graphics, and that such a vector?

Bitmap image, digital image – is a data file or structure representing a rectangular grid of pixels or dots of colors on a computer monitor, paper and other mapping devices and materials. That is, raster graphics – is an image format that contains information about the location, quantity and color pixels.

The main advantage of raster graphics is the creation (reproduction) of almost any image, regardless of complexity, in contrast to, for example, from a vector, which is impossible to accurately convey the effect of transition from one color to another (in theory, of course, possible, but the file size 1 MB in BMP format will have 200 MB in vector format).

Vector Graphics (another name – Geometric Modeling) – is the use of geometrical primitives such as points, lines, splines and polygons to represent images in computer graphics. The term is used as opposed to raster graphics, which represents an image as a matrix of pixels (dots).

Initially, the human eye perceives the image like a bitmap image. The image is projected onto the retina, consisting of individual, reacting to the light cells. Next, the system of eye-brain recognizes the image individual objects, geometric shapes, which was easier to handle and store.
