| Paint program | Programs that allow the user to create and edit bitmapped graphics |
| Draw program | Programs that allow the user to create or edit vector graphics |
| Bitmap/raster | Consist of grids of tiny dots called pixels and have a fixed resolution and cannot be resized without altering image quality |
| Vector | created from mathematical formulas used to define lines, curves, and nodes (drawing points), edited in draw programs, resolution-independent |
| RGB (red, green, blue) | used in computer and TGV monitors and most desktop printers; creates colors by mixing the three colors in varying amounts |
| CMYK (cyan, magenta, yellow and black) | used in color printing, creates colors by removing colors to create others |
| Color depth | the number of distinct colors an image can contain, or the number of bits per pixel that can be displayed on a computer screen |
| Indexed color depth | An 8-bit image, which has a color depth of 256 colors |
| Full color depth | A 24-bit image, which has a color depth of about 16.7 million colors |
| Hue | the name given to a color |
| Saturation | the amount of hue in a color relative to the level of white, black or gray present |
| Monochromatic | many values of one color |
| Analogous | colors side by side on the color wheel |
| Complementary | opposite colors on the color wheel |
| Anti-Aliasing | smoothing the lines or transitions between neighboring colors and shapes in an image |
| Dithering | a process that approximates and adds colors that are not part of an image’s original color palette |
| Opacity | the amount something can be seen through |
| Alpha Channels | masks, which let you manipulate, isolate, and protect specific parts of an image |
| Lossless Compression | a process of reducing a file’s size without losing any pixel information |
| Lossy Compression | a process of reducing a file’s size by altering and/or eliminating some pixels |
| GIF (Graphics Interchange Format) | bitmap format, indexed color, supports still and animated images |
| JPEG (Joint Photographic Experts Group) | bitmap format, most common format for digital photographic images and websites |
| TIFF (Tagged Image File Format) | bitmap format, supports any resolution and color depth from 2 to 24 bit, and is the referred file format for desktop publishing |
| RAW (Raw File) | File format that is unprocessed or uncompressed, also call digital negatives for digital cameras |
| BMP (Bitmap) | bitmap format, full-color format, used to create icons, recognized by all operating systems |
| TGA (Targa Format) | primarily used in animation and video |
| PNG (Portable Network Graphics) | bitmap format, primarily used in developing images for the web |
