HOW TO: Crop Image into Thirds and Save Each Image Separately

string inputFile = @"C:\Users\Public\Documents\LEADTOOLS Images\cannon.jpg";
string outputFolder = @"C:\temp";
RasterImageFormat format = RasterImageFormat.Jpeg;
string ext = "jpg";

using (RasterCodecs codecs = new RasterCodecs())
using (RasterImage image = codecs.Load(inputFile))
{
    CropCommand crop = new CropCommand();
    int width = image.Width;
    int height = image.Height;
    int thirdWidth = width / 3;

    // Crop the first third of the image
    using (RasterImage temp = image.Clone())
    {
        crop.Rectangle = new LeadRect(0, 0, thirdWidth, height);
        crop.Run(temp);
        codecs.Save(temp, Path.Combine(outputFolder, $"cropthird.{ext}"), format, 0);
    }

    // Crop the second third of the image
    using (RasterImage temp = image.Clone())
    {
        crop.Rectangle = new LeadRect(thirdWidth, 0, thirdWidth, height);
        crop.Run(temp);
        codecs.Save(temp, Path.Combine(outputFolder, $"cropthird2.{ext}"), format, 0);
    }

    // Crop the final third of the image
    using (RasterImage temp = image.Clone())
    {
        crop.Rectangle = new LeadRect(width - thirdWidth, 0, thirdWidth, height);
        crop.Run(temp);
        codecs.Save(temp, Path.Combine(outputFolder, $"cropthird3.{ext}"), format, 0);
    }
}
