You can use LEADTOOLS Imaging Pro SDK technology in your application.
https://www.leadtools.com/sdk/imaging-pro
The RasterCodecs class allows you to set many options for loading and saving including the TIFF compression types needed to reduce the size of a TIFF image.
Here is some sample code:
string srcTiff = @"FILE PATH TO INPUT TIFF";
using (RasterCodecs codecs = new RasterCodecs())
{
    using (RasterImage image = codecs.Load(srcTiff, 0, CodecsLoadByteOrder.Bgr, 1, -1))
    {
        codecs.Save(image, @"FILE PATH TO OUTPUT TIFF", RasterImageFormat.TifJpeg422, image.BitsPerPixel);
    }
}

Hi, Abraham HENSON.
Thanks for your nice sharing. I also have some code about image resizing process:
[code]Image img = new Image(filename);/ /this is a model image Image cpimg = img.Resize(width, height, Emgu.CV.CvEnum.INTER.CV_INTER_LINEAR);//this is image with resize[/code]
But I wonder how can I use these codes. Do I need another image resizer to help customize the size of images? I am almost a green hand here. Any suggestion will be appreciated. Thanks in advance.

Best regards,
Arron

Hi, according to your description, your problem is how to compress image, anyhow, the following is the image resizing code, and if you wanna see more, you can see this imaging program that i like most.

using System.IO;
using System.Drawing.Printing;
using RasterEdge.Imaging;
using RasterEdge.Imaging.Processing;

private static Image ResizeImage(Image imgToResize, Size size)
{
Bitmap LoadImage = new Bitmap(@"C:\\1.bmp");
Size newsize = new size (width, height);
e.g. Size newsize = new size (150, 250);
}
Image.ResizeImage (@"C:\\1.bmp", new size(150,250));
