Review Bitmap vs. Vector

Can anyone REMIND me what the difference between these two formats is?

Bitmap - images that are a collection of bits that form an image - otherwise known as pixels.
Vector - images that are completely described using mathematical definitions.

So Inkscape Is what?

a VECTOR-BASED program

So GIMP Is what?

a RASTER-BASED or BITMAP program

EXAMPLE:

OPEN "butterfly.jpg"

Explain to them that once pictures are are enlarged to much, they look unnatural and blocky, (zoom in on butterfly) that reducing a picture too much can cause the image to lose its sharpness.

(scale down the butterfly image and then scale back up - show the loss in quality)
Have the students open a browser and type in: www.shodor.org/ ~caviles/gimp/
They should select the link "Download activityImages" folder and download it.
