Pan

The pan function in the CADCamera class allows users to move the camera along its local x and y axes.

The CADViewer demo demonstrates this functionality. See Samples.

The following Pan sample illustrates how you use the pan function:

C#	Copy Code
using System.IO; using ImageGear.Formats; using ImageGear.Formats.CAD; public static void CameraPan(string path, double x, double y) { ImGearCADPage page = null; // Load the file. using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read)) { page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream); } // Pan the camera page.Camera.Pan(x, y); }

Copy Code

using System.IO;
using ImageGear.Formats;
using ImageGear.Formats.CAD;

public static void CameraPan(string path, double x, double y)
{
    ImGearCADPage page = null;

    // Load the file.
    using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read))
    {
        page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream);
    }

    // Pan the camera
    page.Camera.Pan(x, y);
}

VB.NET	Copy Code
Imports System.IO Imports ImageGear.Formats Imports ImageGear.Formats.CAD Public Sub CameraPan(path As String, x As Double, y As Double) Dim page As ImGearCADPage ' Load the file. Using fileStream As New FileStream(path, FileMode.Open, FileAccess.Read) page = ImGearFileFormats.LoadPage(fileStream) End Using ' Pan the camera page.Camera.Pan(x, y) End Sub

VB.NET

Copy Code

Imports System.IO
Imports ImageGear.Formats
Imports ImageGear.Formats.CAD

Public Sub CameraPan(path As String, x As Double, y As Double)
    Dim page As ImGearCADPage

    ' Load the file.
    Using fileStream As New FileStream(path, FileMode.Open, FileAccess.Read)
        page = ImGearFileFormats.LoadPage(fileStream)
    End Using

    ' Pan the camera
    page.Camera.Pan(x, y)
End Sub

The Pan function is generally used for changing position relative to a certain point. If you wish to simply go to a specific position in the view, use the page.Camera.LookAt(x, y, z) or page.Camera.SetPosition(x, y, z) functions where x, y, and z are integers representing the position of the camera on the respective global axes.
