Why rotated rectangle tool can't draw rotated ROI on image?

[yuzaihuan]

I want to use the tool window to draw a rotated rectangle on image, but each time, it seems only draw a rectangle, it can't rotate. Don't know why?

In Vision Assitant, if I use rotated rectangle tool, it will show like this:

Using the cross lines in rectangle, I can rotate my ROI, it is OK.

Run the sample code: C:\Users\Public\Documents\National Instruments\CVI\samples\Vision\2. Functions\Geometric Matching, change     imaqShowToolWindow (FALSE);

to  imaqShowToolWindow (TRUE); 

on line 93#. Compile then run. Seems I also can't rotate my ROI, don't know why?

Please show me? Thank you.
