Hi
Thank you for your interest in Aspose products. You can try to use the following code to achieve this.

public void TestResizeImages_100222()
{
    Document doc = new Document(@"307_100222_srinivasgoud\in.doc");
    // get shapes collection
    NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true, false);
    int imageIndex = 0;
    foreach (Shape shape in shapes)
    {
        if (shape.HasImage)
        {
            // generate image name
            string imageFileName = string.Format("image_{0}.{1}", imageIndex, shape.ImageData.ImageType);
            // get image
            MemoryStream stream = new MemoryStream(shape.ImageData.ImageBytes);
            Image img = Image.FromStream(stream);
            // resize image
            img = ResizeImage(img, 100, 100);
            // save image
            img.Save(@"307_100222_srinivasgoud\" + imageFileName);
            imageIndex++;
        }
    }
}
/// 
/// Resize source image to specifed sze
/// 
/// Source image
/// Target width
/// Target height
/// Resized image
private Image ResizeImage(Image sourceImage, int targetWidth, int targetHeight)
{
    float ratioWidth = (float)sourceImage.Width / targetWidth;
    float ratioHeight = (float)sourceImage.Height / targetHeight;
    if (ratioWidth > ratioHeight)
        targetHeight = (int)(targetHeight * (ratioHeight / ratioWidth));
    else
    {
        if (ratioWidth < ratioHeight)
            targetWidth = (int)(targetWidth * (ratioWidth / ratioHeight));
    }
    Image outputImage = sourceImage.GetThumbnailImage(targetWidth, targetHeight, null, new IntPtr());
    return outputImage;
}

I hope that this will help you.
Best regards.
