Bitmap And Vector By Jordan Gilliland

What is bitmap �A representation in which each item corresponds to one or more bits of information, especially the information used to control the display of a computer screen.

What is a vector �a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.

Bitmap and Vector �A vector image uses geometrical formulas to represent images. The other way of representing graphical images is through bitmaps in which the image is made up of a pattern of dots (note that bit-maps are often referred to as raster graphics).

Apple � The purpose for the apple is to show what kind of product it is. � Apple is known to have very good graphics and that Is for people to enjoy. � The point for graphics and this product is so that people can chat and have fun with good graphics so they see the apps and other stuff on the phone very clearly.

Amazon � The amazon market is very good the tick on the amazon is to show that the market is world-wide and that when you buy something on amazon the thing that you bought is going to be good quality. � And when you go on the website everything you see is very organised and easy to see!.

Tesco � The Tesco (every little helps) is to show that when you go to Tesco it is going to be cheap and also for advertisement. � The website is also very organised like the amazon website, the Tesco is very white and is very clear with hardly many colour but that does not matter if you can see the screen clearly and make your order!.

�A Advantages of Bitmap bitmap is an image which is made up of tiny squares of colour. The arrangement of these tiny coloured squares produce the effect of an image. This is a good method of reproducing 'continuous tone' images, such as photographs. � The amount of detail that can be seen in a picture depends on the resolution of the image; how many times per inch these squares or pixels occur. 300 times per inch is what is needed for good quality reproduction on a commercial printing press, and 72 pixels per inch for monitor display.

Dis-Advantages of Bitmap � Bitmaps have two disadvantages. In terms of the amount of digital storage, bitmaps are memory intensive, and the higher the resolution, the larger the file size. � The other disadvantage with bitmaps is when an image is enlarged, the individual coloured squares become visible and the illusion of a smooth image is lost to the viewer. This 'pixelation' makes the image look coarse.

Advantages of vector � Scalable vector graphics are very different from bitmaps. Vectors describe the shape of an object as a series of points connected by curved or straight lines, represented as a mathematical formula. � The advantages of using vector graphics are; a small file size and the ability to scale the image to any size without loss of quality; see the image above. They are ideal for logo designs, as they can be printed very small on business cards or printed large on a billboard poster.

Dis-Advantages � Vector graphics, however, cannot reproduce 'continuous tone' photographic images like bitmaps. � Vectors describe the shape of an object as a series of points connected by curved or straight lines, represented as a mathematical formula. These lines may have a thickness or stroke assigned to them, and the object they create can be filled with colour.
