RasterImageSetResolution Method
Sets the resolution for this RasterImage.

Namespace: Aspose.Imaging
Assembly: Aspose.Imaging (in Aspose.Imaging.dll) Version: 20.05
Syntax
public virtual void SetResolution(
	double dpiX,
	double dpiY
)

Parameters

dpiX
Type: SystemDouble
The horizontal resolution, in dots per inch, of the RasterImage.
dpiY
Type: SystemDouble
The vertical resolution, in dots per inch, of the RasterImage.
Examples
The following example shows how to set horizontal/vertical resolution of a raster image.
[C#]

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.jpg"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

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

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