Facts on Vector Images
A known fact is that vector images are made up of many individual, scalable objects that are defined by mathematical equations rather than pixels thus they always render the best quality because they are not dependent on devices. Such objects may consist of curves, line and shapes that have editable qualities like fill, colour and outline and altering the attributes of a vector object dies nit affect the object itself thus the person can freely change any number of objects qualities without destroying the core object. It is good to note that an object can not only be adjusted not only using the attributes but also by shaping and transforming it using nodes and control handles. Because vector-based images are scalable they are resolution independent and the person can increase or decrease the vector size to any degree and the lines will still remain sharp and crisp both in print and on screen and an example of a vector object is fonts.
The other advantage of vector icons images is that they are not restricted to a rectangular shape like bitmaps and they can be placed over other objects and the objects below the vector object will still show through and an example is in a logo where a vector circle and the bitmap circle appear to be the same as when seen on a white background.
Vector images have a myriad merits but the primary advantage is that they are not suitable for producing photo-realistic imagery and vector images are usually made up for creating photo-realistic imagery. Vector images are generally made up of solid areas of colour or gradients but they cannot depict the continuous subtle tones seen in a photograph and this explains why most of the vector images people see seem to have a cartoon-like feel and even though vector images are frequently becoming more advanced and the possibilities of vector drawings have increased over the last decade.
Vector icon free images originate from software and vector images can be easily converted to bitmap images by a process called rasterizing and after conversion of a vector image to a bitmap format the person can specify the output resolution of the final bitmap image to whatever size they need. It is pertinent to save a copy of the original vector artwork in its original format before converting it to a bitmap because once the image has been converted to a bitmap the image loses all the great qualities it had in its vector state. If one converts the vector to a bitmap at the size of 100 by 100 pixels and then they decide that they need to enlarge the image they will need to go back to the original vector file and export it again.
