CStats:GetStatus

CStats:GetStatus

The GetStatus method returns a status for the last statistics calculation. A value of 0 indicates success and other values correspond to an error condition.

Syntax

sMsg = CStats:GetErrMsg()

Returns 0 if the last statistics calculation succeeded.

Otherwise, returns an error code.

Remarks

The CStats calculations return a value and not an error message. If you wish to check the result of a calculation, call this method to get the status code. if the status code is not 0, you can fetch the error message using GetErrMsg. Note:This method also returns 0 if there is no CStats object.

Example

The following script checks the MinMaxClipMean calculation for success and prints an error message if it failed:

S = new_stats()	-- create a CStats object
S:Init( I, R )	-- specify CImage and CRect to measure
nVal = S:MinMaxClipMean()	-- returns the mean value
if S:GetStatus() then	-- if calculation failed, this returns nonzero
Msg( S:GetErrMsg() )	-- show the error message
end
