public void SaveJpeg(string path, Image image, int quality)
{
//ensure the quality is within the correct range
if ((quality < 0) || (quality > 100))
{
//create the error message
string error = string.Format("Jpeg image quality must be between 0 and 100, with 100 being the highest quality. A value of {0} was specified.", quality);
//throw a helpful exception
throw new ArgumentOutOfRangeException(error);
}
//create an encoder parameter for the image quality
EncoderParameter qualityParam = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, quality);
//get the jpeg codec
ImageCodecInfo jpegCodec = GetEncoderInfo("image/jpeg");
//create a collection of all parameters that we will pass to the encoder
EncoderParameters encoderParams = new EncoderParameters(1);
//set the quality parameter for the codec
encoderParams.Param[0] = qualityParam;
//save the image using the codec and the parameters
image.Save(path, jpegCodec, encoderParams);
}
此行实际上是一个问题:image.Save(path, jpegCodec, encoderParams);
保存图像 - 路径问题
如果我设置路径= "C:/PathToMyProject/imagename.jpg"
然后保存作品,但如果我使用相对路径,然后我得到错误
一GDI +发生通用错误。
我也试过:Server.MapPath(path)
但没有帮助。
我的问题是如何设置上传文件夹的相对路径?
这是ASP.NET吗? – BrokenGlass 2011-02-03 21:24:09
错误发生时'path'的值是什么? – 2011-02-03 21:24:27
