bitmap and vector images: make sure you know the differences
DESCRIPTION
Not knowing the difference between a Bitmap and Vector image could mean that your visual content leaves you looking unprofessional. Check out the differences in this presentation.TRANSCRIPT
What is a bitmap image?
A Bitmap image = a Raster imageJust in case you were wondering ..
A large GRID with with lots of little squares (= pixels) in it
Figure #1PS. Bitmaps aka 'maps of bits' - seriously..
Colour is placedin each of these squares to build up an image
Figure #2
Stand back from the grid and you'll see a photo image
Figure #3
Area shown on previous slide
Working with Bitmaps
This image is 250 pixels by 250 pixels in size
This image is 100 pixels by 100 pixels in size.The image still looks good.
This image is1000 pixels by1000 pixels in size.
The image is blurry
There's not enough colour to go around
Try and create or buy, as large an image as possible
You can reduce the size of thisimage and it will still look good
But if you try and increase the size of the Bitmap it might become blurry!
● Great for complex photos
● Most programmes can workwith a simple bitmap image
● They aren't scalable to larger sizes
● Files can be very big
● Images not easily edited

Popular Bitmap Formats
What is a vector image?
The points are connected by lines - called Paths
The points are calledAnchor Points(A & B)
A path can be various shapes
The paths can be coloured, have thickness (stroke) and can be infilled with colour
Here's an example of vector art Thanks to artgerm.deviantart.com
Fonts are vector graphics
In some programmes, you can edit the paths of the font - e.g. Inkscape
● File size is usually small
● Scalable, and they remain sharp
● The image is easily editable
Not well suited to photo images
