网站的图片分割问题
下面是我参考的一位大虾的代码，是图片分割的代码。
我是想问代码中的Cropwidth和Cropheight如何确定的。
请问还有其它的方法能把图片分割吗，比如把一张图片分割成９部分，再组合在一起，成为一个９宫图。



public class CropImageManipulator
{
public CropImageManipulator()
{

}

// 不含扩展名的文件名
private string _fileNameWithoutExtension;
// 文件扩展名
private string _fileExtension;
// 文件所属的文件夹
private string _fileDirectory;
public string Cropping(string inputImgPath, int cropWidth, int cropHeight)
{
this._fileNameWithoutExtension = System.IO.Path.GetFileNameWithoutExtension(inputImgPath);
this._fileExtension = System.IO.Path.GetExtension(inputImgPath);
this._fileDirectory = System.IO.Path.GetDirectoryName(inputImgPath);

// 装载要分隔的图片
Image inputImg = Image.FromFile(inputImgPath);
int imgWidth = inputImg.Width;
int imgHeight = inputImg.Height;

// 计算要分几格
int widthCount = (int)Math.Ceiling((imgWidth * 1.00) / (cropWidth * 1.00));
int heightCount = (int)Math.Ceiling((imgHeight * 1.00) / (cropHeight * 1.00));
//----------------------------------
ArrayList areaList = new ArrayList();

System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<table cellpadding='0' cellspacing='0' border='[$border]'>");
sb.Append(System.Environment.NewLine);
int i = 0;
for (int iHeight = 0; iHeight < heightCount ; iHeight ++)
{
sb.Append("<tr>");
sb.Append(System.Environment.NewLine);
for (int iWidth = 0; iWidth < widthCount ; iWidth ++)
{
//string fileName = "<img src='<a target="_blank" href="http://localhost/SRcommBeijingFile/%22">http://localhost/SRcommBeijingFile/"</a> + this._fileNameWithoutExtension + " _" + i.ToString() + this._fileExtension + "'>";
string fileName = string.Format("<img src='<a target="_blank" href="http://localhost/SRcommBeijingFile/%7B0%7D_%7B1%7D%7B2%7D">http://localhost/SRcommBeijingFile/{0}_{1}{2}'</a> />",this._fileNameWithoutExtension,i,this._fileExtension);
sb.Append("<td>" + fileName + "</td>");
sb.Append(System.Environment.NewLine);
int pointX = iWidth * cropWidth;
int pointY = iHeight * cropHeight;
int areaWidth = ((pointX + cropWidth) > imgWidth) ? (imgWidth - pointX) : cropWidth;
int areaHeight = ((pointY + cropHeight) > imgHeight) ? (imgHeight - pointY) : cropHeight;
string s = string.Format("{0};{1};{2};{3}",pointX,pointY,areaWidth,areaHeight);

Rectangle rect = new Rectangle(pointX,pointY,areaWidth,areaHeight);
areaList.Add(rect);
i ++;
}
sb.Append("</tr>");
sb.Append(System.Environment.NewLine);
}
sb.Append("</table>");

//----------------------------------

for (int iLoop = 0 ; iLoop < areaList.Count ; iLoop ++)
{
Rectangle rect = (Rectangle)areaList[iLoop];
string fileName = this._fileDirectory + "\\" + this._fileNameWithoutExtension + "_" + iLoop.ToString() + this._fileExtension;
Bitmap newBmp = new Bitmap(rect.Width,rect.Height,PixelFormat.Format24bppRgb);
Graphics newBmpGraphics = Graphics.FromImage(newBmp);
newBmpGraphics.DrawImage(inputImg,new Rectangle(0,0,rect.Width,rect.Height),rect,GraphicsUnit.Pixel);
newBmpGraphics.Save();
switch (this._fileExtension.ToLower())
{
case ".jpg":
case ".jpeg":
newBmp.Save(fileName,ImageFormat.Jpeg);
break;
case "gif":
newBmp.Save(fileName,ImageFormat.Gif);
break;
}

}
inputImg.Dispose();
string html = sb.ToString();
return html;
}
}
