| Transparency | Background of an image is see-through |
| JPEG | Joint Photographic Experts Group |
| TIFF | Tagged Image File Format used for high resolution printing |
| Vector | Graphics composed of math formulas that define lines, shapes, and curves. |
| Node | Points you can move to change a shape in vector graphics. |
| Photograph | Raster images that contain millions of colors. |
| Artwork | Computer created drawing or painting; raster or vector |
| Gradient | Filling an object with smooth transition from one color to another. |
