“Paint” = Bitmaps, “Draw” = Vectors
Computers handle images in two ways: as bitmaps, or as vector images
(also known as object-oriented graphics). When working with objects
and vectors, the computer keeps a “display list” that describes a series of
points in space and their attributes.
The rough draft for the fish was done in Corel PHOTO-PAINT®. Once
the client approved it, the image was recreated with shapes so it could
easily be resized for various uses.
What size should you work
at? That depends on your finished
product. Will the artwork ever be used
for other purposes? Remember, it is
always easy to make the image smaller,
but it is very difficult to make it
bigger.
If you have to increase the size
of an image, the best place to do that is
on the scanner; blowing up a bitmap in
a software program is always a bad
idea.
Each scanner has a different
interface, so you may have to explore a
little to find the settings you need.
