# BitmapViewer Constructor 
 
Creates new instance from 3D array of pixels.
 
**Namespace:** [Aurigma.GraphicsMill.WebControls](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_WebControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.WebControls (in Aurigma.GraphicsMill.WebControls.dll)
 
## Syntax
  
```
Public Sub New
```
 
```csharp
public BitmapViewer()
```
 
## Examples
 This code demonstrates how to create gradient image from array. ```
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    ' Declare array of RGB pixels with dimensions 128x128
    Dim pixels As Integer(,,)

    ' Do not forget that due Visual Basic syntax you should specify not the 
    ' number of items, but the latest array index. I.e. if we want to create
    ' 128x128 image with 3 channels, we should pass values 127, 127, and 2.
    ReDim pixels(127, 127, 2)

    ' Generate a multiple color gradient
    Dim I, J As Integer
    For I = 0 To pixels.GetLength(0) - 1
        For J = 0 To pixels.GetLength(0) - 1
            pixels(I, J, 0) = 128
            pixels(I, J, 1) = (CDbl(J) / CDbl(pixels.GetLength(0))) * 255
            pixels(I, J, 2) = (CDbl(I) / CDbl(pixels.GetLength(1))) * 255
        Next
    Next

    ' Create new bitmap from this array
    Dim bitmap As New Aurigma.GraphicsMill.Bitmap(pixels, Aurigma.GraphicsMill.PixelFormat.Format24bppRgb)

    ' Display the bitmap on form.
    Dim g As Graphics
    g = Me.CreateGraphics()

    bitmap.Draw(g, 0, 0, bitmap.Width, bitmap.Height, Aurigma.GraphicsMill.Transforms.CombineMode.Copy, Aurigma.GraphicsMill.Transforms.InterpolationMode.HighQuality)
End Sub
``````csharp
