Bitmap &
Vector Graphics
Bitmap
Research: The picture used here is an SD
memory card from amazon. The picture itself is a Jpeg and was most likely
chosen as such as it gives a detailed image of the product while also saving on
memory size.
The image
used is of a piece of text that is used on the apple website. The reason why it
is a PNG is so that it is able to be used ontop of other pictures due to its
transparent backround.
Vector
research:
The reasons
why these vectors were produced as such
was so that they could be scaled to any size and be able to be put on posters,
canvases etc. theres no loss of quality on an image when its scaled and so
nothing from the artwork is lost or deformed.
On the left
is a vector, as you can see there isnt any anti-aliasing on the text making it
good for logo's while on the right you can see a bitmap image. As you can see
there is anti-aliasing and this makes the edges jaggy when zoomed in. this is
fine for things such as text however is a poor choice for logo's.
Anti aliasing is the process of smoothing out the edges of an object and text.
