Imatest Documentation Options II for setting folder options, SFR save file suffix, etc. Global folders The default folders for opening files and saving results can be set globally using the second group of controls. Normally (with Global folder for opening files unchecked), the default folder for opening files is changed only for the Imatest module in use: one module at a time. When it is checked, the default folder for opening files is changed for all modules. This can be convenient if project data for several modules is stored in the same file. When either of the Global folder for saving results... radio buttons is set, the default save folder is changed for all modules whenever the input folders are changed. EXIF data acquisition This selects the program used to read EXIF data: image file metadata that contains camera and lens settings. Selected EXIF data (important values such as aperture, exposure time, ISO speed, and focal length) is displayed in several figures and EXIF data is saved in CSV and XML output files. There are four settings: 1 Get EXIF data from jhead.exe (default; JPEG-only, limited) Default 2 Get EXIF data from Phil harvey's ExifTool (all file types; must download & install) Recommended 3 Get EXIF data from ExifTool & save ALL EXIF data in csv output (LOTS)! Detailed! 4 Do not get EXIF data (for rare cases of errors) EXIF off Setting 1, jhead.exe, is the default. Jhead is a compact program with limited capabilities included in the Imatest installation file. It only works with JPEG files, and it captures limited EXIF data. Settings 2 and 3 (ExifTool; introduced with Imatest 3.2.1) work with virtually any file type and capture virtually all available EXIF data. If the setting 3 (save ALL EXIF) is selected, all the EXIF data— a huge amount; some quite obscure— is written to the CSV output files. The second and third settings require that ExifTool be downloaded and installed. Go to the ExifTool home page and download the Windows standalone executable (a zip file). This file is not included in the Imatest installation because it is frequently updated. In Windows Explorer, double-click on the downloaded zip file. Copy the contents ( exiftool(-k).exe ) to the Imatest installation folder (typically C:\Program files\Imatest in English-language installations). Rename exiftool(-k).exe to exiftool.exe. The final selection is for very rare cases (e.g., industrial prototypes with non-standard EXIF data) that cause the EXIF read routine to crash. Suffix for saved SFR plots and CSV and XML files Normally the root name (input or selected file name ) is followed by the channel, ROI orientation (AL = above left (relative to the center), etc.) and distance from the center in percentage of distance to the corner. Example: rootname_YAL79_MTF.png for the Edge/MTF plot. An alternative can be selected where _ROI_ followed by the ROI number nn is used in place of the orientation and distance. Example: rootname_ROI_03_MTF.png 90 of 451
Imatest Documentation Special user code enables custom features for specific users. Normally blank. Reset restores defaults: it sets SFR ROI filtering to Normal, Stepchart ROI selection to Automatic, turns off all global folder settings, and checks Get EXIF data . Help opens a relevant web page on computers connected to the Internet. Dropdown menus Dropdown menus are located at the top of the Imatest main window. Most items duplicate the controls elsewhere in the window, but some are unique. File contains Clear Memory, Close Figures, and Exit. Clear Memory removes the image data stored after running SFR. This may release enough memory to speed up other modules, such as Light Falloff, which can use large amounts of memory. Modules opens the Imatest modules. The entries duplicate the buttons on the left of the Imatest main window. Settings contains functions that control various aspects of Imatest operation. Small / Normal / Large fonts alters the font size in output figures and GUI windows. The default is Normal. The setting is saved between runs. This address problems with tiny fonts in high resolution screens (1600x1200 pixels and above) or larger than expected fonts which appear when the video card DPI setting is Large size (120 DPI) instead of Normal. The video card setting can be accessed by right-clicking on the Windows background, then clicking Properties, Settings, Advanced, General (tab). Large fonts are displayed if DPI is set to Large size (120 DPI). 96 DPI is normal. Windows may need to be rebooted before new settings take effect. Save Settings copies settings from imatest.ini (which stored the current, active settings) to a named file (with extension ini). Particularly useful for saving regions of interest (ROIs) for SFR runs and for controlling Imatest API modules. The most recent folder used to save or retrieve settings is displayed in the file selection dialog box, but any folder may be selected. Load Settings retrieves settings from a named file (with extension ini) and stores them in imatest.ini. It is useful for restoring ROIs or for restoring settings after they have been reset. The most recent folder used to save or retrieve settings is displayed in the file selection dialog box, but any folder may be selected. View Settings displays the settings— the contents of imatest.ini— in the Notepad viewer. You can edit this file (with care!) and save it as a named file if desired. You can send us the contents of imatest.ini for help with troubleshooting. The Notepad window should be closed when you are finished viewing it: it may interfere with some Imatest operations. Reset defaults restores settings to their default values by resetting imatest.ini. On rare occasions this clears bugs. See Troubleshooting. It is a good idea to save settings prior to resetting them. Edit/reset module(s) opens a special editor that allows ini file values to be examined and entire sections to be deleted if the corresponding module crashes. Described in Troubleshooting. Options and settings I and II contain settings that affect SFR ROI (region of interest) error checking, Stepchart ROI selection, and folder names for storing results, and more. DOS command allows you to enter a DOS command while Imatest is running. Useful for troubleshooting, for example, for diagnosing path issues. When checked, Fixed sharpening radius keeps the SFR standardized sharpening radius fixed, even for edges with poor MTF where it would otherwise automatically increase. IT options sets several options for controlling IT (Industrial Testing) runs. Enlarge hi res figs applies only to high resolution screens (1600x1200 pixels and above). When this box is checked (by default), images are enlarged so they don't look tiny on the screen. Unchecking the box turns this feature off. Images are smaller but better suited for website presentation. The setting is saved. Help contains Online Help, Register, Register Upgrade, and About, and Welcome window. Online Help corresponds to the Help button; it opens a browser window. Register and Register Upgrade are used to register Imatest. About displays the Imatest version and user registration information. Check for updates opens a web page that shows the latest version. Welcome window displays the window that normally appears when Imatest is started in evaluation model. 91 of 451
