.NET 的：

    protected string tmp = "";

    protected void Page_Load(object sender , EventArgs e) {

        Bitmap bm = new Bitmap("d:\aa.jpg");

        int w = bm.Width;

        int h = bm.Height;

        StringBuilder sb = new StringBuilder();

        Color c;

        sb.Append("

imagecolorat returns the color index (position in the palette) for
palette based image or the color value for true color images.

imagecreatefromjpeg creates true color images, always.
imagecreatefromgif creates always palette based images and
imagecreatefrompng creates either palette or true color images as PNG
supports both image types.
