Introduction:
I have decided to compare Raster (bitmap) and Vector graphics & their uses in modern digital multimedia.
I will begin by defining what both mean. Then take a brief look into how they were first utilised.
Give examples of their pros and cons, their uses now & express my opinion as to which one I believe to be better option and why.
Raster (bitmap) graphics definition:
“A raster graphic is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds to an individual pixel on a display. In a standard bitmap image, each dot can be assigned a different colour. Together, these dots can be used to represent any type of rectangular picture.
There are several different bitmap file formats. The standard, uncompressed bitmap format is also known as the "BMP" format or the device independent bitmap (DIB) format. It includes a header, which defines the size of the image and the number of colours the image may contain, and a list of pixels with their corresponding colours. This simple, universal image format can be recognized on nearly all platforms, but is not very efficient, especially for large images.” (techterms, 2014)
Text Box: Figure1To reduce file size other bitmap image formats ie. GIF, PNG, and JPEG incorporate compressed algorithms. The type of compression used differs with each format, but they all represent an image as a grid of pixels. Uncompressed BMP files are significantly larger than compressed bitmaps so take longer to download. Which is why the majority of images seen on the web are compressed bitmaps. Regardless of the file format, your image will look blurry when zoomed in on because each dot will take up more than one pixel.
Common raster formats Include: BMP ...

SVGT (SVG Tiny version) is the mobile phone version of SVG. Not only can these images exploit anti-aliasing they can count links and be displayed as wallpaper.
Conclusion:
In conclusion, designers have to choose how they express their creativity by either using vector or raster graphics. By understanding the differences between the graphic types own particular strengths and their limitations the best results can be achieved.
Ultimately it depends on what graphic/image you wish to create and what you intend to use it for that will determine which type you will choose.
For photo-realistic images, then raster is the solution. If you need to resize and manipulate the graphics & download speeds are important to you, then you should consider vector-based format. Luckily we can have both!
If you gamers have ever played the Nintendo Entertainment System or the Super Nintendo Entertainment System, then you know that games used to be 8-bit and 16-bit. This means that games used to be very poor in graphics. They didn’t have the capacity for many detailed designs.

The first sets of the visual analysis are on drunk driving and drug use. All of these pictures relate to drunk driving and drug use and why it is bad for us to drive under the influence of alcohol or drugs. In the first visual set, there are drunk driving and drug use advertisement pictures that are more effective than the others.
Many do not consider where images they see daily come from. A person can see thousands of different designs in their daily lives; these designs vary on where they are placed. A design on a shirt, an image on a billboard, or even the cover of a magazine all share something in common with one another. These items all had once been on the computer screen or on a piece of paper, designed by an artist known as a graphic designer. Graphic design is a steadily growing occupation in this day as the media has a need for original and creative designs on things like packaging or the covers of magazines. This occupation has grown over the years but still shares the basic components it once started with. Despite these tremendous amounts of growth,
Illustrator, which allows me to create my own unique designs, creates vector graphics and vector text. Illustrator invites me to explore more expressive ways to design.To help you b etter understand the terms Vector Graphics and Vector Text, I will give you the definition of both. Vector Graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way. Vector Text is a text that uses a font created only with line segments. It is very useful to be scaled and very fast. Vector Images take up less storage space and can also be downloaded faster. Vector Images can also be scaled to any size without losing quality. Illustrator can be used online, print, in video, and even on my cell phone. However, I can not apply filter to vector images. The illustrator software is user friendly tutorials to help me use illustrator better are all over the Internet. Whatever I need to learn about adobe illustrator, there’s a tutorial for that.

Graphic design is a type of art that has been around almost since the beginning of time. Its main purpose has always been to communicate something to the viewer, and this communication is being done through visuals and in some cases typography as well. An era of graphic design that revolutionized design into what we now know it as today is the Swiss design era. Specifically, work done by Armin Hofmann. His work is what kick started modern graphic design. His designs have a clean, minimal feel, which is popular even in today’s graphic design. Hofmann as well as other Swiss graphic designers in the modern art movement really set the bar for designers who came after them. The post-modern

As a part of under graduating course I presented my major project on JPEG Encoding and Decoding using MATLAB technology, which included going from a basic grayscale bitmap image all the way to a fully encoded file readable by standard image readers.
As I have been using some of the graphics software program such as Adobe Illustrator and Photoshop CS6 their lots of innovation and creation to play around and I have used...
Infographics are so popular because audiences can absorb the information quickly and conveniently. It today’s hectic, fast-paced world, anything that is quick and convenient is seen as desirable.
Pictures, images or graphics are a very useful way of brightening up a document and making it more appealing and interesting for the end user. Graphics can be added to Word in a variety of ways, including inserting; Pictures, Clip Art, Shapes and SmartArt. When images are added to a document it is important to consider the graphic formatting options available, such as cropping, wrapping, styles, effects and position (graphics will be discussed in detail in LO2).
