For more information on how to use INI files in Imatest IT, we recommend the Imatest INI File Reference
For Imatest IT, most of these entries don’t need to be entered. Many don’t affect Imatest IT results: they control interactive figure displays or figure output formats (figures are often not used in Imatest IT).
| Background | Meaning |
| Yellow | Yellow background: Important to Imatest IT. Parameter and Description are in boldface. [IT] |
| Cyan | Cyan background: Figure settings. (Figures are used infrequently for IT.) [f] |
| Gray | Gray background: For interactive operation. No effect on IT. |
| Clear | Clear background: Results details (units, scaling, etc.) for CSV and JSON output, or not yet categorized. May affect IT results. |
| Notes: Parameters of special interest to IT users are indicated by [IT] and displayed in Boldface. Some entries have extra values (unused; there to make it easy to add more settings). | ||||
