powerpoint of the various files

1. Graphic files and format
From Rashpal Reehal
Within this PowerPoint I will discuss the following file formats: raster,
vector, metafiles and file extensions. Also applications such as vector and
raster applications and how they are used in different media forms

2. Raster files
Raster files are digital images which are created (for example scanning
something in)
Raster files are stored in ‘image files’, formats often vary
A raster file is usually larger than a vector file. This could be also known as
a ‘Bitmap’ reason being is because the image is made up of individual
squares which form a image.
When doing my own work raster files were important as the software I was
using supported ‘raster files’, the software I used was InDesign and
Photoshop this was to create my mixmag front cover and double page
spread, this meant that I had to include them even if my image was
pixelated. What I did to make it smooth and clear was I never zoomed the
image too much I kept it at a size were I thought it was suitable.
Here is a example of what I mean
when you zoom in too much.
This was when I zoomed in my
MIXMAG front cover as you can see
the individual squares are making up
the image

3. Examples of where I’ve used raster files
I used Photoshop to create my MIXMAG front cover, as you can see I
tried to keep the image at a right size, but if I did zoom it in then it
would pixelate
InDesign, I used this software
To create my MIXMAG double page
spread
Example of where I used
Photoshop, I used to create
my mixmag magazine

4. Vector files
Vector files is the creation of images through digital, this is done
through a sequence of commands or it could be a mathematical
statement that are placed in lines and shapes
Vector graphics are based on images which are made up of vectors
which lead through locations called ‘control points’
When doing my work vector files were important as they are linked with
the software I used such as ‘InDesign’ and also making my record label
and CD cover vector files were involved. When using a software
supporting often when zooming in the image will ‘pixelate’ and it will
become ‘unclear’ here is an example of what I mean;
This shows how it
looks like when
zooming in, reason
this happens is
because this software
supports ‘vector files’

5. Examples of where I’ve used vector files
Record label, this again was made on Photoshop, this also supports
vector files
CD, I created this on Photoshop, this software again supports vector files
InDesign, This again supports vector files and here I created my MIXMAG
double page spread

6. Metafiles
A metafile is a file which contains information that describes or specifies
different files
A metafile includes to different elements, this may consist of both vector
and raster files
Here is a example of metafiles;
This is a example of a vector file, I created
my title on Photoshop which supports
vector files
This is a example of a raster file, the
software I made this in again supports
raster files
The mixture of both vector and raster
files makes it a ‘metafile’

7. File extensions
A file extension is a suffix to the name of a computer file, this is applied to
indicate the file format
Examples of file extensions are; .png, .jpeg, .exe, .dmg and .txt.
Some file systems limit the length of a extension
When doing my MIXMAG project there were a number of different file
extensions which were on a document here are examples;
This is an example of a file
extension, here the file extension is
.PSD and .PDD

8. Vector and raster applications
This is a vector file as some elements This is a raster application as some
involved were made on a different of the elements included were
software, for e.g. Photoshop made on a different media forms
