The following example shows how to set horizontal/vertical resolution of a PNG image.

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.FileFormats.Png.PngImage pngImage = (Aspose.Imaging.FileFormats.Png.PngImage)image;

    // Get horizontal and vertical resolution of the PngImage.
    double horizontalResolution = pngImage.HorizontalResolution;
    double verticalResolution = pngImage.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");
        pngImage.SetResolution(96.0, 96.0);

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