Solution (AVS)

  1. Use the code from the Gasket Inspection example to prepare the inspection.
  2. From the Project Explorer window create a new UserType named InspectionPacket. All the inputs, which need to be created, as well as their corresponding data types are shown in the image below.

  3. From the Project explorer window create a new SavingQueue with the InspectionPacket data type.

  4. From the Project explorer window create a new Worker Task called SaveLastImage.

  5. Add the Queue_Push filter to the main program's PROCESSING section and assign it the SavingQueue queue.

  6. Right click on the inValue of the Queue_Push filter and select "Expand Structure Fields".

  7. Connect created inputs using the following scheme:

  8. Go to the SaveLastImage Worker Task macrofilter.

  9. In the ACQUIRE section add the Queue_Pop and the Loop filters.

  10. In the PROCESS section add following filters in specified order: the DrawRectangles_SingleColor, the DrawCircles_SingleColor, the DrawCircles_SingleColor, the DrawSegments_SingleColor, the DrawArcs_SingleColor, the DrawArcs_SingleColor, the DrawSegments_SingleColor and the SaveImage.

  11. Right click on the outValues of the Queue_Pop filter, select the PropertyOutput and check all visible outputs.

  12. Connect created outputs by following the scheme in the image below.

  13. Set the inFile input of the SaveImage filter to LastResult.bmp.

  14. Program is ready to use. In the current version, programs using worker tasks can be properly run only in the Run mode (F5).
