Content included in posters that would be displayed in a gym and methods by which these posters can be created

Link to the scenario

Tom wants to attract more members to his classes so he has decided to create posters advertising the forthcoming week’s sessions.

These posters will combine graphics and text.

Graphics software

G

raphics

software

or image editing software is a program or collection of programs that enable a person to manipulate visual images on a computer

.

Computer

graphics can be classified into two distinct categories: raster graphics and vector graphics

.

Vector vs bitmap (Raster)

Vector

Vector graphics

are created in graphics packages

They consist of shapes called

objects

. Even if an object in a vector graphic is quite large, it doesn't need a lot of computer memory. Therefore the file size of a vector graphic is often very small.Vector graphics are scalable - ie when you resize them, they do not lose quality.

Bitmap (Raster)

When you take a photograph using a digital camera or scan an image from a magazine, you are creating a

bitmap graphic

.

A bitmap graphic is composed of many tiny parts, called

pixels

which

make the images look realistic

Since the computer has to store information about every single pixel in the image, the

file size

of a bitmap graphic is often quite

large

.

When you resize a bitmap graphic, it tends to

lose quality

Vector vs bitmap

Examples of graphics software

Adobe Photoshop

Adobe Fireworks

Microsoft Picture Manager

Microsoft Photo Editor

Microsoft Paint

Mac PaintiPhotoPicasaSerif PhotoPlus

graphic manipulation software

Photos can be edited using a program on your computer or in your web browser

. Common features include:

Air

brushing

Red-eye

removal Cropping Special effects Brightness and contrast

Graphic painting software

Painting

software is used to create original pieces of work using

input devices like your

mouse or graphics tablet. A graphics tablet is a touch-sensitive surface that you draw on with a pen. It reproduces what you draw on screen. They are generally preferred by professional designers.

Windows Paint

is the most basic painting software and is included with the Windows operating system (free software). Programs with more features are Adobe Photoshop (paid for software) and GIMP (open source) which also allow you to edit photos.

Graphic drawing software

Drawing

software has similar features to painting software but uses

vector

and outputs

vector images

. Vector images are made up of lines, curves and shapes based on coordinates. Examples of drawing software: Adobe Illustrator Inkscape Xara Xtreme Note: Vector images do not lose quality when they are resized

Graphics software – file types

Graphics

software can read and save to lots of different file types. An image’s file type or file format should be chosen based on its intended use

.

Make notes on the file types mentioned at the start of the Bitesize activity:

About – Adobe Photoshop

Adobe Photoshop is a raster graphics editor developed and published by

Adobe Systems

It

can edit and compose raster

images

Photoshop has vast support for graphic file formats but also uses its own PSD and PSB file formats In addition to raster graphics, it has limited abilities to edit or render text, vector graphics, 3D graphics and video.

About – adobe fireworks

Adobe Fireworks

is

a bitmap and vector graphics editor

.

Fireworks was created specifically for web production

. In terms of image compression, Fireworks has a better compression rate than Photoshop with JPEG, PNG and GIF images.Animated World Books could benefit from using Fireworks as they are likely to be uploading content on to their website.

Open File type vs Proprietary file

type

Can open in lots of different programs

Free for companies to use in their programs

Some graphics

programs have their own file type that only they can open and save in. These are called proprietary file formats. Companies keep how the file works a secret so you have to use their software

Desktop Publishing

Desktop publishers are often used to produce newspapers, magazines

, posters,

newsletters and leaflets

.

The main advantage of desktop publishing is that it is

frame based. Text and picture frames can be laid out on the page, and moved and resized as necessary.Text and graphics can be inserted, e.g. from clip art, word art and imported from other sources too. For example, text written by a professional writer or photos and illustrations provided by a professional designer.Publisher comes standard with templates to help users create professional looking documents
