The vector images are defined mathematically, based mostly on their geometric characteristics. To be precise, a vector image is described by a set of geometric primitives that describe factors, lines, curves, and polygons to which we can attribute colors and shades. They are radically completely different from raster images, which are described as a grid of properly colored pixels.
1. In most cases, vector images would require lesser disk house than a bitmap. They are principally fashioned by flat colors or easy gradients because of which they don’t require a whole lot of disk space. Lesser the information to create the image, smaller is the file size. Thus, they are given more preference in comparison to different images.
2. Vector images do not lose quality when they’re scaled. In precept, a vector image can be scaled indefinitely. In the case of matrix images, some extent is reached the place it is obvious that the image consists of pixels. Thus, the quality of vector images is superior to other forms of images.
3. They can be simply saved and modified within the future. The very best part is that, the process of modification is quite easy as well. All kinds of changes will be simply managed without any difficulty. Even if a file is modified, the resultant file does not occupy numerous space. This is one other reason why they are used throughout industries.
4. The process of making them is quite easy as well. Actually, utilizing easy drawings we are able to get advanced vector images without a number of difficulty. Simple and person-friendly programs reminiscent of Macromedia Freehand, Corel Draw and Adobe Illustrator can be used for creating easy drawings, which will be transformed to vector images.
1. They are usually not suitable for encoding pictures or movies taken within the “real world” (for instance – pictures of nature), though some codecs help a mixed composition. Virtually all digital cameras store images in bitmap.
2. The data used to explain them have to be processed by a powerful machine, i.e. the computer must be highly effective enough to carry out the mandatory calculations for forming the final image. If the data quantity is high it could gradual down the rendering of the image on screen, even when working with small files.
3. Another disadvantage is that, even small drawing errors are often seen, when the images are enlarged to certain extent. Such an incident can have an effect on the quality of the images, particularly when they’re used within the field of animation.
Despite the fact that vector images have a couple of disadvantages, they have a wide range of applications and are implemented in the fields of computer graphics, architecture and engineering etc.
