What is a vectorized image?
In principle, there are two ways of representing visual data on the computer: through dots and geometry. The method using dots in which each pixel is said to where to go is sometimes known as bitmap imaging and more often known as raster graphics . The method using geometric formulas is known as vector or vectorized graphics
Historically vectorized images were often used because they required much less memory than raster images. Most of the oldest graphics used graphics that were characterized by long arches, circles and other simple geometric shapes, because only a few lines of mathematics could be represented than a detailed description where each pixel had to appear. Once computers are progressing and memory has become a less problem, vectorized images have become less commonly used in most applications where they were replaced by raster images. However, vectorized graphics still remainHe sees something like a revival of popularity, for many reasons. If you want to see how beneficial it can be, imagine a simple shape like a circle. In the raster picture, a circle, which is 100 pixels wide, will have to store where each of the pixels in this area is 1,000 pixels. If someone should approach this picture, it would begin to see pixelization because only the 1,000 pixels were described.
On the other hand, in a vectorized image, a simple mathematical formula would describe the radius of the circle and the fact that it is a right circle, and the processor could calculate the rest. Not only is this much less information that we have to deal with, but if someone should approach the picture, it will continue to have a smooth line, because the processor would only continue to calculate the arc of the circle. This allows vectorized images much easier to handle - grown or reduced, twisted and bent- without any distortion or quality loss. This also means that higher resolution monitors show vectorized images as higher -resolution graphics, while raster graphics have the maximum resolution set to perceive, after which no point is visible.
Vectorized images are commonly used in design with assisted computer, in many rendered images for special movie effects and increasingly for computer animation. The popular flash format uses vector images, allowing much higher resolution in much smaller files than traditional raster graphics, making images ideal for Internet applications and movies.
The constantly developing field of computer intelligence is automated raster to convert vector. Many programs try to automate the process of raster graphics transformation - such as painting or photography - into a vectorized version, which can then be easier to handle and in many cases can be much smaller in SO sizepermission. Many vector image programs, such as Freehant, include the Trace tool that automates this process, and there are a number of specialized applications, each with its own pros and disadvantages.
