How do I save non-linear calibration parameters?

[Steverino]

If I do a non-linear calibration, how do I save and re-apply them to succeeding images, without having to re-do the calibration if I exit my program?

I am using VB and IMAQVision.

Thanks!

Hi Steverino,

The calibration information is saved as Vision Information.  Once you have calibrated an image, save it to disk using WriteImageAndVisionInfo.  In your other program you can load this image using ReadImageAndVisionInfo.  To calibrate a new image, simply call SetCalibrationInformation.  It is important to note that both images must be the same size.
