The term ‘Graphic design’ describes the planning and thought process necessary to create effective visual communication. There are several issues to consider when compiling a screen design and the following subsections consider the various elements of the design. It should be noted that there are no hard and fast rules associated with screen design. All that can be provided is a serious of guidelines which assist the designer to construct ways and means of communicating visual metaphors. Many initial aspects of screen design can be done most effectively with scissors and paper. The brief is the description of the subject matter of concept. However you choose to address it, the brief needs conscious planning. Each image must have a meaning, as should each use pf type, color, line, space, plane, shape, scale, balance and texture. All these combine to create a visual language which communicates the concept to the viewer. Layout once the concept has been decided upon, the next step is to determine a layout which will communicate the intention of each screen. An effective layout can make complex information easier to understand. When planning a layout, keep in mind that, in the /English-speaking world, we are culturally conditioned to read a page from top left to bottom right. This makes the top left corner the primary focal point or the place where the eye will initially look when presented with a page of screen. Design decisions can be made to allow for this tendency by placing the dominant element in this position. Alternatively, emphasis can be placed on other areas of the screen by implementing other design strategies. For example, the eye will generally travel from the largest screen element to the smallest. Careful consideration of color can have the same effect; the eye being led to the strongest of darkest color first. The standard layouts shown in are examples of well-balanced alternative ways of leading the eye to different parts of the screen. Whichever one is chosen will be determined by the types of individual screen elements which are involved and their relative importance. It is a good idea to work within the framework of the final screen size to enable more precise positioning of each element. Paper cut-outs can be used to represent text and graphics and can then be moved around to achieve the best results of the shapes and sizes require can just be penciled in roughly. Many computer hours will be saved by working out a rough sketch beforehand. This will also allow other members of the design team to proceed with their tasks.
What is Bit-Map?
A representation for the graphic/image data in the same manner as they are stored in video memory.
There are two types of graphics – a) Bitmap/Raster Graphics and b) Vector Graphics
What is Bitmap / Raster Graphics?
Bitmap graphics also called raster graphics. Use a grid of small squares known as pixels to represent graphics.
Each pixel in a bitmap image has a specific location and color value assigned to it. While working in bitmap images you edit pixels rather than objects of shapes. Bitmap images are resolution dependent, that is they represent a fix number of pixels as a result they can appear jagged and large detail if they are scale on screen of if they are printed at higher resolution then they were created form.
Software example of raster graphics – Adobe Photoshop, MS-paint etc,.
What is Vector Graphics?
It describes graphics according to their geometrics characteristics. You can move, resize of change the color of the image without losing the quality of a graphics.
A vector graphics is not resolution dependent that is you can scale it to any size and print on any output device at any resolution without loosing clarity.
Software example of Vector graphics – Corel Draw, Adobe Illustrator, Macromedia Freehand etc,.
What is resolution?
No or pixels in a digital image (higher resolution always yields better quality).
What is pixel?
Picture elements in digital images or a unit of digital image.
