Vector
& Raster
Raster;
Raster graphics are images that are made up of pixels. It is an array of pixels
of various colours that make up the image. This makes it so that when zooming
into a Raster image, it would get distorted as the image shows. Usually seen in
a gif or Jpeg.
Vector; vector graphics are images made up of paths. These
lines are either straight or curved. The data file for a vector image contains
the points where the paths start and end, how much the paths curve, and the colours
that either border or fill the paths. Vector graphics are also usually saved as
an .eps or an adobe illustrator file.
Because vector graphics are not made of pixels, the images
can be scaled to be very large without losing quality. Raster graphics, on the
other hand, become "blocky," since each pixel increases in size as
the image is made larger. This is why logos and other designs are typically
created in vector format -- the quality will look the same on a business card
as it will on a billboard.
