Task 1 – Technical Glossary
Vector Images – A vector image is an image
which you have rendered out from a programme such as Photoshop and illustrator
made up of lines and dots. You may be thinking what am I on about, the image
looks completely fine and there are no lines or dots but that depends on the
image, some images you will be able to tell straight away that it is a vector
image but if you can’t then zoom in to the image and you will notice the lines
and dots. Here is an example of a Vector image:
Here is the link for this image -
As you can see with this vector image you can clearly see
where the lines and dots are. The good thing about vector images is that there
scalable which means that you can resize it without losing its quality. You can
save a vector image as the following formats EPS, AI, PDF, SVG, DXF – These are
all the formats that make the image a vector image. Believe it or not you can
actually turn a bitmap image into a vector image by using online file format
converters.
Here are the sites I used to help me:
Raster Images – A raster image is basically an image made up
of pixels which has been made in a programme such as Photoshop or illustrator.
It is very clear whether or not an image is raster or not because you can
clearly see the pixels around the image or in other words the image pixelated.
This is how you can tell if an image is raster or not. Just because an image is
raster this doesn’t mean it makes the image look worst it just changes the
texture and the way the image looks, which some people may prefer, especially
people that like playing computer games that were made a long time ago when
game consoles was first created because the graphics were very pixelated. A
raster file is usually larger than a vector image file, raster files can also
be converted into a vector file which can come in handy, and this can be done
using the tools in certain software’s such as illustrator. Here are some
examples of raster image files: JPG, GIF, PNG, TIF, there are also many, many
more raster image files.

Here are the sites I used to help me:
The pixel – a pixel you will notice when you zoom into a
bitmap image and you will see the pixels that the picture is made up off, you
can also see pixels in computer games. For example an image is made up of
thousands and thousands of pixels in columns and rows. The smaller the pixels
the more there will be and the better the quality of the image will be.
here is a link to an example image:
Colour depth - which can also be known as bit depth, can
either be the number of bit depths used to indicate the colour of 1 single
pixel, in either a video frame buffer or a bitmapped image, or the number of
bits used for each colour component of one pixel. It is also the number of
colours that could be shown by a piece of hardware or software. The reason
colour depth is sometimes referred as bit depth is because it is related to the
amount of bits used for each pixel. The more depth there is, the wider the
colour range will be.
Heres an example image:
Sites I used to help me find the information:
Colour models –This is the search for a comprehension of mainly
what color is and how exactly it functions and this has been going on now for
hundreds and hundreds of years. Many many models and systems have been
developed over the years. Color models are a system for making a variety of
colors which are from a set of primary colours such as red, blue, yellow etc.
There are only two types of color models which are subtractive and addictive.
Addictive color models use light to show color whilst subtractive models use
printing inks. Colors that
are come across in subtractive models are the overall result of reflected
light.
Heres an example image:
Here are the links to the websites I used to gather this
information:
Resolution – There are several types of resolution: image
resolution and display resolution. For example the screen resolution is how
good quality it is, another example is when you’re watching a YouTube video and
you’re watching it in 1080p, 720p, 360p and etc. the noun meaning of this is a
film decision to do or to not do something. This can also mean a formal
expression of either an opinion or an intention made. Resolution is where you
analyse a complex notion into a much simpler one. Resolution is mainly the
process or capability of making different individual parts of an object for
e.g. optical images and the sources of light.

Here are the websites I used to help me gather this
information:
Anti – Aliasing – this is the smoothing of the image caused
by aliasing. With images, approaches include changing and reorganizing pixel
positions or setting pixel intensities so that there is a more gradual
transition between the color of a single line and the background color.
Here’s an example of anti-aliasing:
This shows us that this
is where you smoothen jagged, pixelated lines
