Q: Is this vector art?
Vector graphics are made of lines, points and curves, often called shapes.
They are defined by mathematical objects called vectors.
They are usually created in a drawing program such as Adobe Illustrator or CorelDRAW.
Since they're made up of lines and shapes defined by math, they can be scaled down or
up without losing edge definition or quality.
The computer simply recalculates the math and redraws the image to whatever size you choose.
Vector graphics use mathematical relationships between points and the paths connecting
them to describe an image. Vector graphics are composed of paths.
A raster art file is a bitmap image.
It's usually created in an image editing or painting program such as Adobe Photoshop, Corel
PHOTO-PAINT or Corel Painter.
These images are made up of pixels.
A photo taken on your digital camera is a raster image.
Unlike vector files, raster artwork is resolution dependent, meaning that if you enlarge an
image, it loses detail.
The original size of an image is made up of a fixed number of pixels each assigned a color
value and location.
If you see jagged edges on a printed image, it means that the image doesn't have enough resolution.
A bitmap image uses a grid of individual pixels where each pixel can be a different color or
shade. Bitmaps are composed of pixels.
The image to the left below is representative of a bitmap and the image to the right is
representative of a vector graphic. They are shown at four times actual size to exaggerate
the fact that the edges of a bitmap become jagged as it is scaled up:
