Vector Graphics
A free program that creates vector
images is Inkscape
Inkscape does not draw
raster graphics.
It creates .svg files
You can on the other
hand save a .png file
but it is just a raster
snapshot of the image.
So what the heck is a .svg file?
(scalable vector graphic)
It is a xml text file that store information about
objects that are drawn. The image to the
right has three objects. The main thing to
note is that we can grab the object and move
them around at any time.
We CANNOT do this in Paint.net since it paints
pixels to the image and then forgets the object
you are painting.
Try it.
Here is the start of a xml-svg file.

The name of this language is XML (extended markup language) Its also heavily
used in web pages.
You can make these guys any size you want and you get no
pixelization. Cool.
From within Inkscape you can export the
image in any size you want to a .png file or
you can save as .wmf or .emf files which
CAN be inserted into powerpoint
Office doesn’t speak .svg
