Info

Imatest Documentation If you fail to find Imatest-lib.exe or if you suspect that it was downloaded incorrectly, download it by right-clicking here or on any of the links in this section, then reinstall Imatest. Imatest-lib.exe is a self extracting zip file that places the Matlab runtime library in subfolder bin\win32 and toolbox\matlab of the Imatest installation folder. If problems persist, check to see that these folders are populated, then send e-mail to Imatest support with the text of the error message, if any, that appears in the DOS window. Missing DLL files In rare instances, four DLL files, jpeg_depth.dll, dataread.dll, imjpg8.dll, and rjpg8c.dll, may be missing from subfolder toolbox\matlab\iofun\private\ of the Imatest installation folder. Because they are not included in Imatest-lib.exe they are installed using a different procedure, which fails in fewer than 1% of installations. If you get a message that indicates they may be missing, you should check for them in the subfolder and install them manually if they are absent. In Imatest 3.1 or later, the four files are installed to the Imatest installation folder as well as the subfolder. They can be copied to the subfolder ( \toolbox\matlab\iofun\private\; C:\Program Files\Imatest\toolbox\matlab\iofun\private\ in English language installations) if they are missing. For earlier versions you can download jpegdlls.zip and copy the contents to the subfolder. Runtime errors If Imatest does not run as expected, the DOS window that normally stays minimized may contain helpful information. You can open it by clicking on the Imatest DOS Window icon in the taskbar. Here are some potential problems. An Imatest run may fail if the image file path name contains non-Latin characters. We have seen such a failure with Chinese characters. The error message was The error message caught was : Invalid file identifier. Imatest.ini, the file that contains settings stored when modules are run, may have gotten corrupted. Imatest.ini (and also rescharts.ini, multicharts.ini, etc.) contain saved settings that speed up Imatest runs. It is created when Imatest is first run. Settings include regions of interest (ROIs), plot selections, plot scales, and calculation techniques. Sometimes a setting gets corrupted and causes Imatest to crash. Ini files are text files structured so that section titles are enclosed within brackets ( [ ... ] ) and lines have the form name = value, e.g., nwid_save = 2601. [section] name1 = value1 name2 = value2 ... [next_section] There are several things you can do if you suspect that an ini file has been corrupted. In the Imatest Main window (or in the Rescharts or Multicharts windows), click Settings, Reset defaults (all). This deletes imatest.ini, then recreates it with a few default values. The sections are repopulated when modules are run. Click Settings, View settings (ini file). This opens imatest.ini in a simple editor (Notepad) that you can edit (if you have any idea what to change), then save by pressing control-S. You can also copy the contents and paste it into an email to Imatest support, as described below. Click Settings, Edit/reset module(s) to open the INI file Editor/Debugger, shown below. 434 of 451
Imatest Documentation You can select a section to view or delete from the Section dropdown menu. To edit a line, select it in the large window, make the change in the edit window just above the large window, then press Enter. To delete the entire selection, press the Delete section contents button. When you are ready to save the changes press the Save button, which is grayed out until changes are made. If you with to cancel your changes, press either Reload ini file or Close . If you cannot solve the problem, send an e-mail to Imatest support. Tell us your operating system. Attach imatest.ini, which may contain helpful information for diagnosing the problem. You can open imatest.ini (or multicharts.ini or rescharts.ini) by clicking on Settings, View settings (ini file) in the Imatest, Multicharts, or Rescharts windows, then you can copy the contents from Notepad and paste them into your e-mail. The ini files are located in %AppData%\Imatest, where %AppData% is a DOS environment variable whose file name can be determined by entering the command, dir "%AppData%" in a DOS window. You don't need to know the actual location unless the error closes the Imatest DOS window. A typical English-language Windows Vista location is C:\Users\your name\AppData\Roaming . In installations prior to Imatest 2.3 (the first release compatible with Windows Vista), the full file name was C:\Program files\Imatest\imatest.ini. (or counterparts in non-English installations, for example, C:\Programme\Imatest \imatest.ini in Deutsch.) When a version of Imatest prior to 2.3 is replaced with a newer version the file is automatically copied to the new location. Problems may occur when the %AppData% folder name contains non-Latin characters. (We are looking into this. The best solution may be to delete the old imatest.ini or move it manually.) Send the text of the error message, if any, that appears in the DOS window. (See the box below for instructions on getting a screen dump from the DOS window.) The Command (DOS) window Imatest runs from a Command window (resembling a traditional DOS window) that normally stays minimized. When a run terminates unexpectedly or just stalls, the DOS window may contain useful debugging information. To get the DOS window contents, Click on the Imatest icon in the taskbar (usually at the bottom of the screen) to bring up the DOS window. Procedure 1: Copy and paste text (simple, but a little tricky) Right-click inside the DOS window, then click on Select All in the context menu. Alternately, you can click on the icon on the upper-left of the window, click on Edit, click on Mark, then drag the cursor to select the text to copy. Press Enter (or Return) on the keyboard. This is equivalent to Ctrl-C (Copy) in Windows (which doesn't work in the DOS window). Paste the text into your e-mail using a standard Windows Paste command (Ctrl-V or Edit, Paste). It's OK to delete obviously irrelevant text before you send the e-mail. 435 of 451
