SFRreg INI file reference — Imatest Documentation

For more information on how to use INI files in Imatest IT, we recommend the Imatest INI File Reference

This document was created by running sfrreg in Imatest 5.2.0. ALPHA on 31-May-2019 14:48:43.

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.
