builder.InsertImage(ImageDir + "Logo.jpg");

// When we save the document as an image, we can pass a SaveOptions object to
// edit the image while the saving operation renders it.
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.Png)
{
    // We can adjust these properties to change the image's brightness and contrast.
    // Both are on a 0-1 scale and are at 0.5 by default.
    ImageBrightness = 0.3f,
    ImageContrast = 0.7f,

    // We can adjust horizontal and vertical resolution with these properties.
    // This will affect the dimensions of the image.
    // The default value for these properties is 96.0, for a resolution of 96dpi.
    HorizontalResolution = 72f,
    VerticalResolution = 72f,

    // We can scale the image using this property. The default value is 1.0, for scaling of 100%.
    // We can use this property to negate any changes in image dimensions that changing the resolution would cause.
    Scale = 96f / 72f
