Settings window


The Settings window is displayed by pressing the Settings button on the toolstrip.


Program settings can be viewed and maintained from the Settings window. The settings are described in detail in Settings.


The Settings window is displayed modally, it must be closed before continuing to use the Screen Ruler.


The areas and controls on the screen are described below:



  1. Order by Category (the default sort order), or order alphabetically by Setting.
  2. Category (settings with similar usage are grouped in the same category when ordered by Category)
  3. Setting name and value. Some settings have default values. When the defaults are changed the value appears in bold. 
  4. Selected setting highlighted by mouse click
  5. Extended description displayed for the selected setting. Drag the horizontal separator line to resize the description area.
  6. Settings export and import buttons:


When changing folder names or colours a small button appears on the right hand side to help select the required value (e.g. the button shown on the right of FITSStackingFolder above).

Export settings to a text file in the Settings Export Folder

Settings can be exported to a text file and used to restore (import) settings if needed, e.g. if the program has to be re-installed.

The SettingsExportFolder setting must be configured before settings can be exported.

The exported settings are contained in a tab-delimited file named <machinename>.ScreenRuler.AppSettings.<yyyymmdd>_<hhmmss>.cfg where

<machinename> is the name of the computer

<yyyymmdd> and <hhmmss> is the date and time when the settings were exported.


Import settings

To import settings previously exported, use one of the following methods:

  • Drag and drop a valid settings .cfg file on the Import button. 
  • Press the Import button to be prompted with:



Either copy and paste one or more tab-delimited settings from a valid settings .cfg file, or enter the file name (including full path) of a valid .cfg file. The settings will be imported when OK is pressed.


When settings are imported, all the incoming settings will overwrite any matching existing settings. Any existing settings that are not included in the import will be left unchanged.
