LineProfile Problem with ChangeType Error (works with IPP9.2 and not with IP10)

Matthias_Bl

I have to change from Image Pro Premier 9.2 to Image Pro 10 and in the used Makros the LineProfile analysis ist not working. The LineProfile is used in different ways to detect edges in Images. In the code there should be created a circle as a LineProfile with 360 FixedNumberOfSamples. The image is in the "Bild_Canvas_erstellen". 

The phenomena is now, that if I wan't to assign the "FixedNumberOfSamples" I get an Error "ChangeType not supported" if I am running the code. Also is is not possible to display the SampleMode variable with the Debug.Print command.

If I am setting a break Point in the code, everything works in the upper Debug Window. There I get the property of the SampleMode Variable and I can also set it to the FixedNumberOfSamples, what's not possible in the code.

Als also mentioned, the code runs perfect in IPP9.2.

Because I haven't programmed the code myself, I hope somebody has an idea what's the problem here...

Thank you and Greetings

Matthias

Hi Matthias,

We had a temporary problem with scipting module, which was fixed in IP 10.0.11, so if you have earlier version of IP 10, please update it to the latest 10.0.11 version (your macro works in my tests in IP 10.0.11).
Let me kknow if the update fixes the problem.

Yuri

Hello Yuri,

where can I download the 10.0.11 Version?

With the default options you supposed to get the update dialog automatically at startup. If you don't see that, than you can click "Check for Updates" button in the Help button dropdown:
