Hi,

ImageEnView1.IEBitmap.GetIEVisionImage().adaptiveThreshold
thresholdType ievTHRESH_TRUNC not working


when run

ImageEnView1.IEBitmap.GetIEVisionImage().adaptiveThreshold(

spinEdit1.Value,
ievADAPTIVE_THRESH_GAUSSIAN_C,
ievTHRESH_TRUNC, // ievTHRESH_BINARY, //
spinEdit2.Value,
spinEdit3.Value

);

always give a exception of "class EOleException with message 'undefined error'"

but ievTHRESH_BINARY works well.

IEVision verion 4.0.0.0_22342

Sorry, this is not correctly documented

For adaptiveThreshold() the only permitted threshold values are ievTHRESH_BINARY or ievTHRESH_BINARY_INV.
