What happened to LightMeterRectangle in Vision .NET class library?

[Steverino]

There was a very useful function in the CWMachineVision library called LightMeterRectangle. Is the equivalent function available in the 2009 Vision .NET class library?

Thanks!

Hello Steverino,

Most of the functions that used to be in CWMachineVision were not ported over to .NET,however, they will be moved to .dll in the future. Nevertheless, You can take the existing VB code that we ship and convert it. C:\Program Files\National Instruments\Vision\Examples\dotNET\3. Applications\Meter\vb

The light meter rectangle function in the CW library returned a report containing information about the intensities in the selected region.

• Histogram
• IntensityRange
• Interval
• Meanintensity
• StandardDeviation
• StartValue

I am a little suprised that NI didn't port it over yet. It is a very fast way to check for the absence or presence of a part if there is a large enough difference in intensity relative to the background.
