Raster graphics are made up of pixels and have a fixed resolution, so scaling can cause quality loss. Vector graphics are defined by points and curves, allowing scaling without distortion. Common file formats include JPEG for photos, TIFF for documents, GIF for animations, and BMP, PSD, AI, and WMF for graphics. Compression reduces file sizes but can lower quality, while optimization improves loading speeds. Factors like file content, size, and naming impact storage and organization of digital graphic assets.

2. Raster Graphics
• Raster Graphics are digital images made up of bitmaps, bitmaps are a
graphic made up of pixels, every 1,000,000 pixels is a megapixel,
bitmapped images have a fixed resolution, so scaling of the image can
cause loss in quality, the raster files (bitmaps) are directly mapped to the
display.

3. Vector Graphics
• Vector Graphics, also known as vector paths are defined by 2 points, a
start and an end, with curves, angles and points between them, this is
used to create images such as lines, curves, squares and triangles vectors
have no loss in definition, so if an image is scaled, it will not be distorted
or pixelated, this is an advantage of Raster Graphics, as raster graphics do
have loss in definition, so scaling can cause loss of definition in raster
graphics.

5. JPEG
Stands For Joint Photographic Experts Group
Used For/Example JPEGs can be used to display photographs and
web formats.
Advantage JPEGs have small file sizes, leaving more room,
the JPEG format is compatible with browsers,
mobile phones, tablets etc.
JPEG files are good for small prints, such as,
business cards or photo booth pictures.
Disadvantage Loses quality when edited multiple times, when
an image is edited it either gets compressed or
recompressed, hence, losing quality.

6. TIFF
Stands For Tagged image file format
Used For/Example Saving documents, such as an adobe InDesign document.
Advantage TIFFs can save multi-page documents and no quality is loss
when compressed/ recompressed. File size can be reduced if
using lossy compression such as JPEG algorithms.
Disadvantage Files sizes are large and will take up more room compared to
the JPEG format.
Some websites will not support TIFF documents, when a
website allows it, it will be a slow download speed, even
when some websites allow these file formats they take a long
time to lode.

7. GIF
Stands For Graphic Interchange Format
Used For/Example Used to create short, low quality animations.
Advantage No need to show a full, lengthy video, file sizes
are small due to it being a short animation,
loading time is quick due to the small file size,
GIFs can be used to entice a younger audience,
because they are short and simple animations
Disadvantage Animations can be pixelated, making the quality
look very poor.

8. BMP
Stands For Bitmap Image File
Used For/Example The BMP format stores data for colour in
each pixel, For example, a 10x10 pixel BMP
image will include colour data for 200
pixels. (information found at http://techterms.com/definition/bmp )
Advantage Quality is not lost when compressed or
recompressed, BMP files support all
versions of windows, BMPs are good for
small images, or icons.
Disadvantage Large file sizes, so more room taken up

9. Vector Graphics

10. PSD
Stands For Photoshop Document
Used For/Example PSD files are used for image manipulation,
storing pictures made/edited in photoshop,
such as, magazine cover.
Advantage PSDs allow you to save layers, so you can go
back to a specific image and edit it, PSDs do not
lose quality when compressed.
Disadvantage PSD files can only be viewed in photoshop, so if
you want to look at a PSD file, you must have
photoshop, PSDs cannot be uploaded to social
media sites or blogs.

11. AI
Stands For Adobe Illustrator
Used For/Example AI can be used for the creation of logos and
company graphics, detailed cartoons and
technical diagrams
Advantage Using AI offers more flexibility in the workspace,
meaning better quality images. AI increases
productivity as it includes panel editing.
Disadvantage If an amateur AI user first uses it, it may take
some experience and training to master it.
Detail is key, so the user must be patient and
observant.

12. FLA
Stands For Flash File
Used For/Example FLAs are used to create animations and video
games.
Advantage High quality files are produces, which comes in
small file sizes, this means great quality with
less room taken up, FLAs can include sound and
video.
Disadvantage FLA formats do not run on the web, leaving less
use for the files.

13. WMF
Stands For Windows Metafile
Used For/Example Used for storing logos
Advantage No loss in definition when scaled, giving more
flexibility WMFs can contain both vector and
bitmap components, which also gives it more
flexibility, files can be directly placed in
Microsoft word and saved as a JPEG, old
programs will support WMFs
Disadvantage WMF files can glitch when pasted into
PowerPoint, especially if it is a graph of some
sort.

14. File Format Capture
and Optimising

15. Compression
Definition Compression is the process of reducing file sizes
by reducing the amount of information that is
saved in an image etc.
Advantage Compression can give the ability to make
professional business cards with ease or scale
an image to the size of a billboard, without
losing quality, depending on the file format used
Disadvantage Some files may lose quality when compressed,
leaving images pixelated, blocky and very
unprofessional, making it difficult to scale
images to the size of billboards of business
cards.

16. Image Capture
Method Scanner
How is it used for image capture of
graphics
A scanner can digitise images such as sketches,
physical images and media products.
Method Camera
How is it used for image capture of
graphics
Using a camera is easy and efficient, with a click
of a button, you can make high quality images.
Method Graphics Tablet
How is it used for image capture of
graphics
Using a stylus to create images with enhanced
control and flexibility, graphics tablets can be
used for drawing, handwriting and easy
selection

17. Optimising
Why would you optimise? Optimised images will ensure easy viewing on
the web, optimised images will also decrease
file size, larger file types will take longer to
download
How can you optimise? Shrinking the image can help the image load
faster, you should never enlarge the image, this
means asking for more quality, leading to slower
loading times.
Advantage to optimising Images must not be more than 500 pixels wide,
optimised images can be easier to view on the
web and reduce file size.
Disadvantage to optimising There is a chance quality will be lost, due to a
smaller image size, this will mean, faster loading
times, but quality will be lost.

18. Storage

19. File Size
What could affect a Working Scale
(Photoshop) document file size?
The amount of information in the document
can affect the file size, such as, colour, text and
images, the more information in the
document, the larger the file size.
How could you reduce the file size of a
Working Scale document without
affecting quality?
On Photoshop, when a document is selected,
click ‘Image’ and then ‘image size’ click the
‘constrain proportions’ and lower the pixel size
of the image.

What is an advantage of scaling up images
before exporting?
Scaling up images can allow you to attach the
image to larger scale things, such as billboards
and poster easily.
What is a disadvantage of scaling up
images before exporting?
Quality may be lost in if you scale up the image,
it can become blocky and pixelated.

20. File Naming Conventions
What naming conventions could you use
when creating your video game assets?
• You could use names of the characters,
levels, and items used in the game, so you
can easily navigate through the files to find a
certain asset to the video game.
Why is it a good idea to accurately name
your assets?
Accurately naming your assets will make
navigation a lot easier, if you are looking for a
certain file, you can easily browse through the
documents, searching for a certain name.

21. Asset Management
Why would you use folders when storing
your assets?
Using folders to store assets can help keep your
documents organised and clean, so you can
navigate from folder to folder without getting
confused or lost.
What folders would you create and what
would you save within them
• I would create folders for a specific part of
the project I am on, I would save specific
details and parts of the project within the
folders, to make easy, smooth navigation
through the folders.
