Raster to Vector Conversion
Raster image is a dot matrix data structure. It is a shape of rectangular grid of pixels or points of color. Again, a bitmap image assembles bit -for-bit with an image on a screen. On the contrary, a vector image is the use of polygons. It is based on vectors which lead through locations called control points or nodes. However, both image formats are so much important in the fields where images play the key role. Raster images are used in the purpose which demands low quality whereas the vector images are used for high quality works.
Comparison between Raster and Vector
There are two categories of every digital image. One is raster and the other is vector. There are some basic difference between these two images files and those individual features have made one is superior to another.
First of all, the raster images consist of small dots which are called pixels which can be viewed by zooming at a large scale. Being pixel based, during zooming, the image file gets distortion. The image types like Jpeg, Gif, Png are the raster images found almost every printing catalogs and on the web. A vector image consists of lines which has shapes mathematically defined such as curves, lines, filled areas etc. Because of its mathematical equation, it can be enlarge at any scale. Eps, Ai, Pdf are the vector image file types. The images for logo, banner, billboard etc. are generally created in vector files considering the flexibility of making any sizes. A vector file can be changed into raster files where as the vice-versa is nearly impossible.
Now a question may arise in mind that which one is better, raster or vector? Actually, the answer of this question is totally depends upon the uses of the images of both format. For a realistic image, raster image is better because it is a combination of thousands of pixel which help the image to be presented as it is. Again, the vector images are not as realistic as the raster but it is fully scalable as a result these images can use in the bigger project like billboard, banner and so on. Again, most of the logos of the companies are created as vector files because the logos can be used at any scale.
Why vector image
Vector images can fulfill the demand of pixilated free zooming facility at any scale. If the designer is asked an image which will be scalable that means vector image is wanted by the clients.
