Advantages And Disadvantages of Vector Images
The vector images are defined mathematically, primarily based on their geometric characteristics. To be exact, a vector image is described by a set of geometric primitives that describe factors, lines, curves, and polygons to which we can attribute colours and shades. They are radically totally different from raster images, which are described as a grid of properly colored pixels.
1. In most cases, vector images will require lesser disk area than a bitmap. They're principally shaped by flat colours or simple gradients because of which they don't require a number of disk space. Lesser the information to create the image, smaller is the file size. Thus, they're given more choice in comparison to other images.
2. Vector images don't lose quality when they're scaled. In precept, a vector image might be scaled indefinitely. In the case of matrix images, some extent is reached where it is clear that the image consists of pixels. Thus, the quality of vector images is superior to other forms of images.
3. They are often easily saved and modified within the future. One of the best part is that, the process of modification is quite simple as well. All kinds of changes can be simply managed without any difficulty. Even if a file is modified, the resultant file does not occupy loads of space. This is one other reason why they're used throughout industries.
4. The process of creating them is quite easy as well. In actual fact, using simple drawings we will get advanced vector images without a variety of difficulty. Simple and consumer-friendly programs comparable to Macromedia Freehand, Corel Draw and Adobe Illustrator can be used for creating simple drawings, which can be converted to vector images.
1. They are generally not suitable for encoding pictures or movies taken within the "real world" (for instance - images of nature), although some codecs support a mixed composition. Virtually all digital cameras store images in bitmap.
2. The data used to describe them should be processed by a strong machine, i.e. the computer must be powerful sufficient to carry out the mandatory calculations for forming the ultimate image. If the data quantity is high it might sluggish 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 visible, 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 in the discipline of animation.
Despite the truth that vector images have a couple of disadvantages, they've a wide range of applications and are applied within the fields of laptop graphics, architecture and engineering etc.
