QSI Software Release 7.4


Note that if you have installed many prior QSI software releases, there could be long pauses during the installation of Release 7.4. Do not interrupt the installation process. The installer is cleaning up all prior releases. If you have installed only a few QSI software releases, you likely won't notice the delays at all.

Load the "QSI USB Drivers and Software" first before loading any required application plug-ins.

  3. Adds plug-in for TheSkyX on Macintosh (see Software page for details)
  4. New MATLAB Image Acquisition Toolbox adapter (see below for details)
  5. QSI user guides have been relocated to C:\Program Files\QSI\Manuals

Release 6.4 adds an Image Acquisition Toolbox adaptor for MathWorks MATLAB. The qsiimaq adaptor dll is installed as part of the QSI software and drivers installation. No extra installation proceedure is required. See the readme file in the: C:\Program Files\QSI\MATLAB folder for more information.

Prior to release 6.4 the QSI Windows API had nine properties with enumerated arguments. The enums had the same name as the associated property. This caused a conflict with early binding applications using the #import directive. The properties were silently renamed adding a "_" to the property name during import. In release 6.1, the enumerations have been renamed to avoid the conflict. The new enumerations are: CameraStateEnum; FanModeEnum; FlushCyclesEnum; PreExposureFlushEnum; ShutterModeEnum; ShutterPriorityEnum; CameraGainEnum; AntiBloomingEnum; ReadoutSpeedEnum; Programs using properties with these enum will have to be updated to use these names and then recompiled. This is a compile-time only issue.  After updating your source code with the new "Enum" enumerations, the compiled program will still run fine on computers running earlier software releases.
