MeasureHorzHistogram Method (CiTools)

Visual Basic
C#
Delphi
JScript
C++/CLI

'Declaration
 
Public Function MeasureHorzHistogram() As System.Integer()

'Usage
 
Dim instance As CiTools
Dim value() As System.Integer
 
value = instance.MeasureHorzHistogram()

public System.int[] MeasureHorzHistogram()

public function MeasureHorzHistogram(): System.array of Integer;

public function MeasureHorzHistogram() : System.int[];

public:
System.array<int>^ MeasureHorzHistogram();

Return Value

An array of integers with the number of pixels in each column.

Method requires bi-tonal image (object.Image.BitsPerPixel = 1).

C#
VB.NET

void MeasureHistogram(string imageFile)
{
    //  Open image file
    CiServer ci = Inlite.ClearImageNet.Server.GetThreadServer();
    CiTools Tools = ci.CreateTools();

    //  Do processing
    int[] Hist; int i; int start;
    Hist = Tools.MeasureHorzHistogram();
    start = 0; if (Tools.Image.IsZone) { start = Tools.Image.Zone.top; }
    for (i = 0; i < Hist.Length; i++)
    { Console.WriteLine("Row=" + (start + i) + " Pixels=" + Hist[i]); }

    Hist = Tools.MeasureVertHistogram();
    start = 0; if (Tools.Image.IsZone) { start = Tools.Image.Zone.top; }
    for (i = 0; i < Hist.Length; i++)
    { Console.WriteLine("Col=" + (start + i) + " Pixels=" + Hist[i]); }
}
