Graphics is a Drawing or Sketch which represents meaningful information. Computer Graphics is used to Create or set the Images in the form of pixels and is drawn on computer screen. Computer graphics can also be used for Gaming, Entertainment, Photography and all other technology platform. It is basically used in Computer Graphics, Animation, UI Design, Geometric Objects etc.
There are 2 types of computer Graphics:
By considering the graphics field as a rectangle shape and separating the rectangle into some kind of two-dimensional array of small pixels, a raster represents an image.
An image generated by a high-resolution digital camera may also contain horizontal and vertical measurements of 4128 pixels and 3096 pixels, enabling the overall image to be 4128 x 3096 = 12,780,288 pixels. Each pixel describes standard pixel values for the picture at that level. (raster graphics typically require significant numbers of pixels, but devices are very adept at handling a large number of objects!).
Here, we have an image to represent the bitmap graphics.
If you enlarge the above image, you can see each pixel of the image. You can now see the borders of the pixels here and measure them to ensure that the picture is actually 16×16 pixels (involving the white pixels at the vertices). The enlarged picture actually looks unconscionably messy, but as the picture will usually not be displayed at this zoom stage, it is decent enough to be used as an icon.
It is simple to construct raster files through existing pixel information stored in a sequence in memory space.
It is also possible to retrieve pixel information stored in a raster file while using a collection of coordinates that enables the information to be characterized in the grid form.
If available, pixel values can be changed separately or as huge sets by changing a gradient.
Raster graphics can transform well to external devices like CRTs and printers in spot-format
Vector graphics use mathematical equations to draw out your designs. These mathematical equations are translated into points that are connected by either lines or curves, also known as vector paths, and they make up all the different shapes you see in a vector graphic.
This allows vector graphics to be scaled to any size without sacrificing image quality as well as maintain a small file size. Common vector file formats are .svg, .cgm, .odg, .eps, and .xml.
Vector files are thin in size since they have less information than bitmap image files.
Vector images are more versatile than bitmap graphics because the graphical fidelity can be increased up and down quickly without any loss.
Vector image files have sharper lines compared to rectangular, pixel-based bitmap graphics, so they are stronger than raster images with straight lines and flowing curves.
When a vector image has minor defects, these are shown when the vector image is greatly expanded.
A static color or gradient is usually loaded with vector images. Comprehensive picture (photo) attributes cannot be viewed as bitmap graphics.
Computer Graphics has the Ability to store complex drawing and display whenever we need.
The use of sound cards to make computers produce sound effect led to other uses the graphics.
It is more flexible and have options as compared to other methods in design. One can make changes and undo them without changing the while design.
Models can he presented in 3D pictures which can be used to identify the weakness in the structures and designing.
This is used in Advertisements for more attractive adverts and billboards.
It require a lot of skills and resources to create which make this costly.
It takes lots of time and efforts to create computer Graphics.
Majority of complex graphical system applications require training before use.
It has lack of intelligence of understanding the real world.
