Useful Information About Vector Images
One of the techniques used for describing images in computer-based graphics is called vector graphics.
A picture or an image described with the help of vector graphics is known as a vector image.
This unique technique utilizes various sets of geometric primitives for defining points, curves, polygons and lines for attributing different colors and shades to them.
Thus, it helps in distinguishing every aspect of an image with the help of colors.
It is very different from another imaging technique known as raster graphics that describes images with the help of grids (colored) of pixels.
Advantages The main advantages of this technique are as follows: · The ability to express data in the form that is easily comprehensible to human beings (e.
g.
standard SVGs ); · The ability to express data in the format that uses very little space; · The ability to enlarge images in an arbitrary fashion, without distorting their resolution.
This technique of image description offers better data compression because vector images occupy lesser space in comparison to raster images.
They are also easier to edit and manage.
This is why, vector imaging technique is very useful in handling projects that require a lot of images of high definition.
They can not only help in saving a lot of time, effort and space, but they can also save a lot of money.
These days, many business organizations and professionals also opt for converting their regular images to vector images for saving space.
Image Quality When a vector image is displayed on any device that has a higher resolution, it will not lose its definition.
If a regular image is enlarged, the quality of the image will not be high and the pixels constituting each section of the image will be visible.
If the same image was stored with the help of vector graphics, the lines constituting the image would be stored as equations that start from a certain point, and are identified with well defined initial and final coordinates.
When images described with vector graphics are enlarged, their view is not distorted and they do not appear pixilated.
Instead, they appear very clear and take full advantage of the display potential of the device.
The vector images are of very high quality and are available in the formats: DXF, DGN, DWG, HPGL, SVG, PDF, EMF and WMF.
They are widely used in the fields of computer graphics, publishing, architecture, engineering and all other fields that require high definition images.
