Bitmap vs. Vector
4
Vector
Vector graphics are made up of objects like shapes, curves, lines and points.
When the graphic is completed it is possible to edit each object seperatley e.g. shape, size, colour or posistion.
Even if the vector graphic is large, it does not need as much memory as a bitmap graphic, so more often than not the file size for vector graphic is only small.
Vector graphics are scaleable unlike bitmap with vector you can make it as big as possible and it will not lose any quality.

Vector Continued
I completed a vector graphic in Adobe Illustarator and this is vector graphic because it is made by shaped and not pixels.
On the film poster I created I took a still image using a digital SLR and it is classed as a Bitmap.
The way you know it is a bitmap graphic is because I took the image myself and when I zoomed in on it on Phtotshop you can see all of the individual pixel.

Bitmap(Raster) vs. Vector
Originally it was a bitmap graphic because it was picture taken from a digital camera and made up of pixels and I then transformed it to a vector graphic because it was then made up of shapes
and curves.
There are 2 main graphical types one being Bitmap(raster) graphics and Vector graphics. Bitmap made up of thousands of different coloured pixels and vector is made up of objects like shapes, points, curves or lines etc.
Bitmap
When a picture is taken with a digital camera it is automatically a bitmap graphic.
A bitmap is made up of thousands of tiny little pixels and every pixel could be a different colour, it is also possible to change every indiviudual pixel
A bitmap graphic is often a large file on a computer because the computer has to save every indivduial pixel.
When you zoom in on a photo you can see the pixels more and more but the further you zoom in the more quality is lost and you start seeing every pixel.
As you can see with this vector graphic, when the graphic is made bigger it doesnt lose any quality of the illustration because it is not made up of pixels like bitmap graphics.
Differences Between Bitmap & Vector
What are they made up of? Bitmap is made up of pixels of different colours and vector is made up of objects
For Bitmap graphics you can edit individual pixels and for vector graphics you can edit individual objects.
Bitmap graphic look real but vector graphics dont look real at all in most cases they look like cartoons.
Native formats that the software can read is for bitmap is .bmp and for vector it is .svg
Common file formats for bitmap graphics are .bmp, .dip jpeg, giff, tiff and .png for vector grapjics they are .cgm, .svg, .odg, .eps and .xml
