The PdfViewOptions class has the following properties to set the image width or/and height:

/// <summary>
/// Max width of an output image in pixels.
/// </summary>
public int ImageMaxWidth { get; set; }

/// <summary>
/// Max height of an output image in pixels.
/// </summary>
public int ImageMaxHeight { get; set; }

/// <summary>
/// The width of the output image in pixels.
/// </summary>
public int ImageWidth { get; set; }

/// <summary>
/// The height of an output image in pixels.
/// </summary>
public int ImageHeight { get; set; }

You can set the width and/or height of the output images. Use one of the following methods:

To render a single image, set ImageWidth/ImageHeight options.
To render multiple images, set ImageMaxWidth/ImageMaxHeight options. If an image exceeds these limits, it is resized proportionally.

Warning
If you set the ImageWidth/ImageHeight options, the ImageMaxWidth/ImageMaxHeight options are ignored.

To set the ImageMaxWidth/ImageMaxHeight options, follow these steps:

Instantiate the Viewer object.
Instantiate the PdfViewOptions object.
Set the ImageMaxWidth and/or ImageMaxHeight values;
Call the View method.

The following code snippet shows how to set the output image size limits:

using GroupDocs.Viewer.Options;
using GroupDocs.Viewer;
// ...

using (Viewer viewer = new Viewer("sample.jpg"))
{
    // Create a PDF file.
    PdfViewOptions viewOptions = new PdfViewOptions();
    
    // Specify the maximum width and height.
    viewOptions.ImageMaxWidth = 800;
    viewOptions.ImageMaxHeight = 600;
    viewer.View(viewOptions);
}

VB.NET

Imports GroupDocs.Viewer.Options
Imports GroupDocs.Viewer
' ...

Module Program
    Sub Main(args As String())
        Using viewer As Viewer = New Viewer("sample.jpg")
            ' Create a PDF file.
            Dim viewOptions As PdfViewOptions = New PdfViewOptions()

            ' Specify the maximum width and height.
            viewOptions.ImageMaxWidth = 800
            viewOptions.ImageMaxHeight = 600
            viewer.View(viewOptions)
        End Using
    End Sub
End Module
