Create()

static HistogramControl BioGTK.HistogramControl.Create ( Channel  channel )

inlinestatic

        {
            Builder builder = new Builder(new FileStream(System.IO.Path.GetDirectoryName(Environment.ProcessPath) + "/" + "Glade/Histogram.glade", FileMode.Open));
            return new HistogramControl(builder, builder.GetObject("histogram").Handle,channel);
        }

HistogramControl_ButtonPressEvent()

void BioGTK.HistogramControl.HistogramControl_ButtonPressEvent ( object  o, ButtonPressEventArgs  args  )

inline

This function is called when the user presses a button on the mouse

Parameters

o	The object that the event is being called on.
ButtonPressEventArgs

        {
            mouseX = (int)args.Event.X;
            mouseY = (int)args.Event.Y;
            this.QueueDraw();
            if(args.Event.Button == 3)
            menu.Popup();
        }

HistogramControl_MotionNotifyEvent()

void BioGTK.HistogramControl.HistogramControl_MotionNotifyEvent ( object  o, MotionNotifyEventArgs  args  )

inline

The function takes the mouse position and divides it by the scaling factor to get the actual value of the mouse position

Parameters

o	The object that the event is being called from.
MotionNotifyEventArgs	This is the event that is triggered when the mouse is moved.

        {
            mouseValX = (float)args.Event.X / fx;
            mouseValY = (float)args.Event.Y / fy;
        }

Init()

void BioGTK.HistogramControl.Init ( )

inline

This function initializes the histogram control.

        {
            if (ImageView.SelectedImage.bitsPerPixel == 8)
            {
                graphMax = 255;
                Bin = 1;
            }
            else
            {
                graphMax = ushort.MaxValue;
                Bin = 1;
            }
            this.Drawn += HistogramControl_Drawn;
            this.MotionNotifyEvent += HistogramControl_MotionNotifyEvent;
            this.ButtonPressEvent += HistogramControl_ButtonPressEvent;
            this.ScrollEvent += HistogramControl_ScrollEvent;
            this.DeleteEvent += HistogramControl_DeleteEvent;
            setMin.ButtonPressEvent += SetMin_ButtonPressEvent;
            setMax.ButtonPressEvent += SetMax_ButtonPressEvent;
            setMinAll.ButtonPressEvent += SetMinAll_ButtonPressEvent;
            setMaxAll.ButtonPressEvent += SetMaxAll_ButtonPressEvent;
            this.AddEvents((int)
                (EventMask.ButtonPressMask
                | EventMask.ButtonReleaseMask
                | EventMask.KeyPressMask
                | EventMask.PointerMotionMask | EventMask.ScrollMask));
        }

UpdateChannel()

void BioGTK.HistogramControl.UpdateChannel ( Channel  c )

inline

This function updates the channel variable with the channel that is passed in

Parameters

Channel

The channel object that contains the channel information.

        {
            channel = c;
        }

UpdateView()

void BioGTK.HistogramControl.UpdateView ( )

inline

‍The function UpdateView() is called when the user clicks the button. It calls the function

QueueDraw() which is a function of the Gtk.DrawingArea widget. This function tells the widget to redraw itself

        {
            view.QueueDraw();
        }
