Uniformity INI Reference

Uniformity ini file reference

Uniformity is included in IT EXE and DLL, hence users may sometimes need to examine or edit the INI file used to control IT versions.

Many of the settings in the [uniformity] section are set by the Uniformity Settings window. A few are set by responses to other windows or user actions. Uniformity shares the same ini file section ([uniformity]) with Uniformity Interactive. Settings that affect only Uniformity Interactive (and hence not the IT versions) will be highlighted in pink.


Uniformity settings window

INI file settings that affect several modules are described in Imatest INI Reference.

Notes
(-IT) Not used in Imatest IT
(gr) Affects graphics (figures). May not be of interest for Imatest IT, where graphics is often suppressed.
(index) Setting is equal to the index of the popup menu. You’ll need to open the Settings window to see these: Never used for important IT settings.
(index-1) Setting is equal to the index of the popup menu – 1 (0 – (index-1)). Keeps backwards compatibility for some settings that were originally 0 (off) or 1 (on), but had options added.
