Examples

This example loads a multi-page ODG image and resizes it using various resizing methods.

[C#]

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

using (Aspose.Imaging.FileFormats.OpenDocument.OdgImage image = (Aspose.Imaging.FileFormats.OpenDocument.OdImage)Aspose.Imaging.Image.Load(dir + "sample.odg"))
{
    // Scale up by 2 times using Nearest Neighbour resampling.
    image.Resize(image.Width* 2, image.Height* 2, Aspose.Imaging.ResizeType.NearestNeighbourResample);

    // Save to PNG with default options.
    image.Save(dir + "upsample.nearestneighbour.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.OpenDocument.OdgImage image = (Aspose.Imaging.FileFormats.OpenDocument.OdImage)Aspose.Imaging.Image.Load(dir + "sample.odg"))
{
    // Scale down by 2 times using Nearest Neighbour resampling.
    image.Resize(image.Width / 2, image.Height / 2, Aspose.Imaging.ResizeType.NearestNeighbourResample);

    // Save to PNG with default options.
    image.Save(dir + "downsample.nearestneighbour.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.OpenDocument.OdgImage image = (Aspose.Imaging.FileFormats.OpenDocument.OdImage)Aspose.Imaging.Image.Load(dir + "sample.odg"))
{
    // Scale up by 2 times using Bilinear resampling.
    image.Resize(image.Width* 2, image.Height* 2, Aspose.Imaging.ResizeType.BilinearResample);

    // Save to PNG with default options.
    image.Save(dir + "upsample.bilinear.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.OpenDocument.OdgImage image = (Aspose.Imaging.FileFormats.OpenDocument.OdImage)Aspose.Imaging.Image.Load(dir + "sample.odg"))
{
    // Scale down by 2 times using Bilinear resampling.
    image.Resize(image.Width / 2, image.Height / 2, Aspose.Imaging.ResizeType.BilinearResample);

    // Save to PNG with default options.
    image.Save(dir + "downsample.bilinear.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
