2. Raster Graphics
• Give a definition of Raster Graphics
Raster graphics are made up of pixels and have a pre-set resolution, so if the person was to
expand or compress the image then the picture will become pixelated and distorted leading to
overall just bad image quality and it will make the picture harder to see.
So when any number of pixels are expanded in an image (when it is a raster graphic) the picture
only becomes distorted because it has the same pixels and the same amount of detailing its juts
they have been spread out across a wider surface.
3. Vector Graphics
• Give a definition of Vector Graphics
Vector graphics are made up of paths or strokes and these paths can become a line or a shape .
With a vector image the definition is never lost, so the image can be expanded and all the same
amount of detailing will be restored. So the edges stay smooth and clean. Which means that
these graphics are better when it comes to specific areas within media, so can be better with
logos. This is so that you don’t have to keep recreating the same image at different sizes just to fit
them on different products, instead you can just change the image accordingly with a vector
graphic. Another good example of what vector graphics could be useful for is for billboards as if
you have created your image slightly small you can quickly make it much bigger, not lose
definition and make it able to be seen on the billboard.
5. JPEG
Stands For Joint Photographic Experts Group
Used For/Example It is used mainly for display images, so can
be used as backgrounds or social media
photos.
Advantage The image already has a good quality due
to the amount of pixels to the size of the
image.
Has a small file size so can easily be stored
and moved around with very little time.
Disadvantage Involves a raster graphic so loses quality
upon compression and expansion.
Therefore doesn’t agree very well with
sharp edges or major changes very well at
all.
6. TIFF
Stands For Tagged Image File Format
Used For/Example A TIFF is used for desktop publishing and Is
used for creating magazine covers or
books.
Advantage Can store multiple pages onto one file so is
popular with graphic designers so that
they can create several different pages and
save them to one document rather than
having many different documents for each
page.
With a TIFF file there is also no quality lost
when the work is compressed.
Disadvantage Has a rather large file size due to storing
multiple pages on one document so
transferring around will take some time.
7. GIF
Stands For Graphic Interchange Format
Used For/Example The gif is used mainly on social media and
websites and are normally really short
collection of images played fast to look like
a moving image.
Advantage An advantage would be that the file size is
so small and can easily be compressed as a
small file so will not take much time to
transfer the file around.
Disadvantage It seems to be an out-dated technology as
there are many more files that can do this.
Once the code has been transferred to a
gif then there is no going back and redoing
the work.
8. BMP
Stands For Bitmap Image File
Used For/Example These are used to store bitmap images,
these are rather complex and a quite
similar to JPEGS.
Advantage The file can easily be created from other
or existing pixel data.
Can easily be transferred to output devices
and translate well to these devices. e.g.
printers.
Disadvantage A large file size is normal with a BMP file
as it stores so much and will take more
time to move around and send to different
people.
10. PSD
Stands For Photoshop Document
Used For/Example Is used to manipulate images and add
layers onto them
Advantage Saves the individual layers that are put
onto the document making transferring
the file, somewhere else and then carrying
on a lot easier.
Disadvantage The file size can be rather large so
downloading and moving the file around
can take quite a bit of time. Compressing
can make not very much difference.
11. AI
Stands For Adobe illustrator Art
Used For/Example Is used to create logos and is a good
software to use for this because of the
vector graphics, this will make the company
look good as the main picture they will see
for them (logo’s) will not be at all distorted
or show clear pixel definition.
Advantage Doesn’t lose definition due to it being a
vector graphic therefore can be scaled to
different sizes and it wont make any
difference.
Disadvantage With the software being for design it can
take several hours to get used to the
software and work out exactly what to do
12. FLA
Stands For Flash File
Used For/Example Is used to create animations and games.
Advantage The person using this type of a file can
make very high quality animations and
keep the file size low.
Can add in sounds to the file to play
alongside the moving animation.
Therefore giving the moving image more
of a depth to the animation whilst
maintaining the low file size.
Disadvantage A disadvantage is that the file cannot be
supported on the internet without a
specific update or installation to fix he
problem which is quite time consuming.
13. WMF
Stands For Windows Metafile
Used For/Example This file is another one that is used for
logos and contains both vectors and
bitmaps. The file is similar to an AI.
Advantage Can be enlarged or compressed as it is a
vector graphic and these do not lose
definition when increased or decreased in
size.
Contain elements of bitmap and vector
components.
Disadvantage With the file only being from windows if
the person trying to use this file is on an
apple mac for example then there will be a
problem with compatibility.
15. Compression
Definition When something is compressed it is made
smaller, this in terms of imagery and
graphics can largely affect the image due
to the amount of pixels included in a
normal picture (JPEG or a TIFF).
Advantage Is the saved file is a vector graphic (PSD or
AI) then no image quality is lost due to this
method.
Disadvantage When the image file is compressed the file
can lose the quality and look pixelated if
the file is a raster e.g. a JPEG or GIF file
format.
16. Image Capture
Method Scanner
How is it used for image capture of
graphics
With the scanner its allows users to capture images by using the
device to make a digital copy of the hand drawn image which
can then be put forward onto a document or easily uploaded to
the internet.
Method Camera
How is it used for image capture of
graphics
With the camera it allows you to take images which
can be put forward onto a computer to create a gif or
be uploaded to the internet.
Method Graphics Tablet
How is it used for image capture of
graphics
A recent development in technology that allows
people to hand draw images and instantly transfer the
data onto the computer screen so you don’t have to
use a mouse to draw an image if you can just draw it
anyway.
17. Optimising
Why would you optimise? Optimization of an image can lead to
making the image easier to view and if
not optimized may take a long time to
download due to the size of the file being
so big.
How can you optimise? to optimise the the image you can do several
different things all of which can decrease the
file size and make it easier to upload and view
on the internet, one of which is by simply
reducing the image size. Other examples include
reducing the bit depth and reducing the
resolution.
Advantage to optimising Can make the file size a lot smaller and
therefore will increase download time as
the file wont need to download as much
data.
Disadvantage to optimising Can reduce saturation from the image and
also can destroy resolution, so can either
show no colouring or just be a picture of a
19. File Size
What could affect a Working Scale
(Photoshop) document file size?
What can affect a working scale
document is pixel resolution and size of
the image, which can also be from hiding
certain layers that can affect the size of
the file.
How could you reduce the file size of a
Working Scale document without
affecting quality?
To reduce the file size of the document
you could just compress (optimise) the
image, if the document is a PSD file then it
will not lose quality becausee it is a vector
graphic.
What is an advantage of scaling up images
before exporting?
If the image has been scaled to a better
size the file size can decrease and
therefore the time it takes to successfully
move the file around will not take very
long.
What is a disadvantage of scaling up
images before exporting?
The different scale factor choices that are
[present are limited so will have to cut
some of the image in order to export it.
20. File Naming Conventions
What naming conventions could you use
when creating your video game assets?
You could separate them out so have one for the planning, one
for all the different elements of production. This could include
having the different images saved in one folder and then all the
animations of the game in another then showing the worlds and
all the architecture within the world to give a proper detailing
into the work.
Why is it a good idea to accurately name
your assets?
So that you know exactly what information is in which file so
finding these will be simple and will not cost time when finding
them.
So having this extra level of organisation can make getting
everything sent around a lot more of an easier task and will save
time.
21. Asset Management
Why would you use folders when storing
your assets?
When keeping folders it is the best way in order
to keep all your files at hand and in a safe folder
where you can organise everything that you
need and not lose the work.
What folders would you create and what
would you save within them
For example the folder could be saved under
the video games and then having all the
different files saved in there in their own
separate folders.
