VGetExtrema Example
VB Example:

Dim xmin As Single, xmax As Single  
Dim ymin As Single, ymax As Single  
Dim seq As String, blob As String  
  
seq = "testSeq"  
blob = "blob01"  
m_spel.VRun(seq)  
m_spel.VGet(seq, blob, "found", found)  
If found <> 0 Then  
    m_spel.VGetExtrema(seq, blob, xmin, xmax, ymin, ymax)  
End If  

C# Example:

float xMin, xMax, yMin, yMax;  
bool found;  
string seq, blob;  
  
seq = "testSeq";  
blob = "blob01";  
m_spel.VRun(seq);  
m_spel.VGet(seq, blob, "found", found);  
  
if(found == true)  
    m_spel.VGetExtrema(seq, blob,out xMin,out xMax,out yMin,  
        out yMax);
