JpegImageVerticalResolution Property
Gets or sets the vertical resolution, in pixels per inch, of this RasterImage.

Namespace: Aspose.Imaging.FileFormats.Jpeg
Assembly: Aspose.Imaging (in Aspose.Imaging.dll) Version: 21.04
Syntax
public override double VerticalResolution { get; set; }

Property Value

Type: Double
The vertical resolution.
Remarks
Note by default this value is always 72 since different platforms cannot return the screen resolution. You may consider using the SetResolution method for updating both resolution values in single call.
Examples
The following example shows how to set horizontal/vertical resolution of a JPEG image.
[C#]

string dir = "c:\\temp\\";

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.jpg"))
{
    Aspose.Imaging.FileFormats.Jpeg.JpegImage jpegImage = (Aspose.Imaging.FileFormats.Jpeg.JpegImage)image;

    // Get horizontal and vertical resolution of the BmpImage
    double horizontalResolution = jpegImage.HorizontalResolution;
    double verticalResolution = jpegImage.VerticalResolution;
    System.Console.WriteLine("The horizontal resolution, in pixels per inch: {0}", horizontalResolution);
    System.Console.WriteLine("The vertical resolution, in pixels per inch: {0}", verticalResolution);

    if (horizontalResolution != 96.0 || verticalResolution != 96.0)
    {
        // Use the SetResolution method for updating both resolution values in a single call.
        System.Console.WriteLine("Set resolution values to 96 dpi");
        jpegImage.SetResolution(96.0, 96.0);

        System.Console.WriteLine("The horizontal resolution, in pixels per inch: {0}", jpegImage.HorizontalResolution);
        System.Console.WriteLine("The vertical resolution, in pixels per inch: {0}", jpegImage.VerticalResolution);
    }

    // The output may look like this:
    // The horizontal resolution, in pixels per inch: 300
    // The vertical resolution, in pixels per inch: 300
    // Set resolution values to 96 dpi
    // The horizontal resolution, in pixels per inch: 96
    // The vertical resolution, in pixels per inch: 96
}
