Digital Graphics Software

Vector graphics and applications

Vector graphics use mathematics to draw pictures and images. You make the images to be precise and they define objects as coordinates and measurements.
Vector applications are programs such as Visio which are basic flow diagrams to computer aided design applications which are very complex and three dimensional. The other application used is called Inscape which is a free Open Source vector graphics application allows you to create images by drawing geometrical shapes like rectangles, lines and curves with your computer mouse.

Bitmap Graphics and software

Bitmap graphics are made from lots of pixels, each pixel has there own colour and these are called raster graphics. The pictures can have different qualities for example if you resize, zoom in or print the image it can look blotchy. Bitmap software can be applications such as paint which uses basic shape and tools. There is more complex software such as Photoshop which uses layers and more precise designing tools.

Photo manipulation software
Graphic designers and people who work with computer graphics to make there work look professional, use software such as Photoshop and Paint Shop Pro
There are many tools you can use to change the image such as red eye, layering images, Magic wand. The file size of the file would be large especially with the quality and how many pixels there are.

Embedded Graphics Facilities
Microsoft Word allows you to insert pictures the quality isn’t very good. You can crop, resize and change the colour slightly. There is other DTP software where you can manipulate graphics like PowerPoint but again the quality isn’t as good as specialist graphics software. The main role of this software is not to manipulate graphics that is why the quality isn’t as good as other graphics software.

I am now going to compare Microsoft word and Photoshop
Word isn’t a programme designed for graphic manipulation so the options available aren’t as sophisticated. The tools that are available for graphic manipulation are crop, resize, change the shade and compress images. There are also graphic features such as autoshape, clipart and 3d shapes. Photoshop is a specialist graphics programme. So there are lots of tools available because it is designed to manipulate graphics. Things like layering images magic wand and getting rid of red eye.

I am now going to demonstrate the use of two techniques in advanced graphics manipulation. I will show before and after shots.

Using a tutorial off PhotoshopLady.com http://www.myinkblog.com/2008/06/11/create-an-awesome-grass-texture-in-photoshop/ I created some grass for the background.
It basically uses the stagger effect and Wind to create the blades of grass.


Below is the picture before I used colour correction.

Here is the picture after I used colour manipulation.

Final design

I created some grass for the background.It basically uses the stagger effect and Wind to create the blades of grass.

Hardware

I am now going to Describe how the following hardware components affect the performance of a computer system used to manipulate digital graphics.

Hard Drive
If you are going to do any thing with graphics you will need a large hard drive to store the capacity. Beacuse the hard drive is used by a computer system to store data the data will include applications that are needed to edit pictures and graphics or the picture itself.

RAM
Improves the speed of creating graphics this will save time. Ram is a type of computer data storage.

Procesors
These can improve the performance of a computer because it lets the computer do more than one things at once. For example a duel core processor can do two times as much as a single core processor can manage this has obvious benifits.

Graphics cards
The graphics card is used to process and show images on the computer screen. you can upgrade graphics cards to produce better images on the screen and quicker prosessing.
