照片是通过URL获取下来的
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(strUrl);
response = request.GetResponse();
stream = response.GetResponseStream();
if (!response.ContentType.ToLower().StartsWith("text/"))
value = SaveBinaryFile(response, imagePath);
保存的方法
private static bool SaveBinaryFile(WebResponse response, string savePath)
{
bool value = false;
byte[] buffer = new byte[2048];
Stream outStream = null;
Stream inStream = null;
try
{
if (File.Exists(savePath))
File.Delete(savePath);
outStream = System.IO.File.Create(savePath);
inStream = response.GetResponseStream();
int l;
do
{
l = inStream.Read(buffer, 0, buffer.Length);
if (l > 0) outStream.Write(buffer, 0, l);
} while (l > 0);
value = true;
}
finally
{
if (outStream != null) outStream.Close();
if (inStream != null) inStream.Close();
}
return value;
}
这样保存的是拍照之后的原图，原图太大，现在要把这张图的大小设定为360*480 再保存，请问应该怎么改 ？
