| Refers to the number of colors per pixel that can be displayed in an image and affects image quality and file size. | Color Depth |
| Refers to the mathematical algorithm used when an image is saved in order to reduce the file size. | Compression |
| No data is lost during compression. | Lossless |
| Some data is lost during compression. | Lossy |
| Ease at which files are opened, modified, and viewed on computers using different operating systems, software and browsers. | Portability |
| The background of an image is “see-through” so that the graphic can blend into the background without having a white box around it. | Transparency |
| Resolution | The amount of detail stored for an image. The higher the resolution, the higher the level of detail in the image. |
| The number of dots of ink or toner per inch on a printed image. | DPI |
| RGB | (red, green, blue) |
| CMYK | (cyan, magenta, yellow, black) |
| Raster Graphics | Also called bitmaps, are images composed of grids of pixels that have a fixed resolution (number of pixels per inch) and cannot be resized without losing image quality. |
| Aspect Ratio | Relationship of an object’s width to its height. |
| Compiling multiple pictures or objects together into one image. | Layering |
| Enlarging or shrinking a graphic. | Scaling |
| Pivoting an object around its center point. | Rotating |
