Examples
The following example loads an image from a file, then saves the image to a PNG file stream.
[C#]

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.bmp"))
{
    Aspose.Imaging.ImageOptions.PngOptions saveOptions = new Aspose.Imaging.ImageOptions.PngOptions();
    using (System.IO.Stream outputStream = System.IO.File.Open(dir + "output.png", System.IO.FileMode.Create))
    {
        // Save the entire image to a file stream.
        image.Save(outputStream, saveOptions);
    }
}
Examples
This example shows the process of Saving an Image to MemoryStream. To demonstrate this operation, example loads an existing file from some disk location, performs Rotate operation on the image and Save the image in PSD format
[C#]

//Create an instance of MemoryStream
using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
{
    //Create an instance of image class and initialize it with an existing file through File path
    using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(@"C:\temp\sample.bmp"))
    {
        //Rotate the image at 180 degree about X axis
        image.RotateFlip(Aspose.Imaging.RotateFlipType.Rotate180FlipX);

        //Save the Image as PSD to MemoryStream with default PsdOptions settings
        image.Save(stream, new Aspose.Imaging.ImageOptions.PsdOptions());
    }
}
Examples
The following example shows how to save an entiree BMP image or part of it to a file or stream.
[C#]

string dir = "c:\\temp\\";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.bmp"))
{
    Aspose.Imaging.FileFormats.Bmp.BmpImage bmpImage = (Aspose.Imaging.FileFormats.Bmp.BmpImage)image;

    // Convert to a black-white image
    bmpImage.BinarizeOtsu();

    // Save to the same location with default options.
    image.Save();

    Aspose.Imaging.ImageOptions.BmpOptions saveOptions = new Aspose.Imaging.ImageOptions.BmpOptions();

    // A palette contains only two colors: Black and White in this case.
    saveOptions.Palette = Aspose.Imaging.ColorPaletteHelper.CreateMonochrome();

    // For all monochrome images (including black-white ones) it is enough to allocate 1 bit per pixel.
    saveOptions.BitsPerPixel = 1;

    // Save to another location with the specified options.
    image.Save(dir + "sample.bw.palettized.bmp", saveOptions);

    // Save only the central part of the image.
    Aspose.Imaging.Rectangle bounds = new Aspose.Imaging.Rectangle(image.Width / 4, image.Height / 4, image.Width / 2, image.Height / 2);
    image.Save(dir + "sample.bw.palettized.part.bmp", saveOptions, bounds);

    // Save the entire image to a memory stream
    using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
    {
        image.Save(stream, saveOptions);
        System.Console.WriteLine("The size of the whole image in bytes: {0}", stream.Length);
    }

    // Save the central part of the image to a memory stream
    using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
    {
        image.Save(stream, saveOptions, bounds);
        System.Console.WriteLine("The size of the central part of the image in bytes: {0}", stream.Length);
    }
}
//The output may look like this:
//The size of the whole image in bytes: 24062
//The size of the central part of the image in bytes: 6046
