[英]A generic error occurred in GDI+ when saving Image
我阅读了相同问题的答案,并做了要求做的任何事情。 如上一个答案中所述,我还为当前用户授予了对该文件夹的写入权限,但仍然收到此错误。 所以,请问有人可以给我具体答案怎么办? 这是我的代码
protected void Page_Load(object sender, EventArgs e)
{
//get all the files in a directory
string[] files = Directory.GetFiles(@"D:\Naved\BasicDotNet\Images");
//combine them into one image
System.Drawing.Bitmap stitchedImage = Combine(files);
//save the new image
stitchedImage.Save(@"D:\Naved\BasicDotNet\Images", System.Drawing.Imaging.ImageFormat.Jpeg);//Error:-A generic error occurred in GDI+
}
public static System.Drawing.Bitmap Combine(string[] files)
{
//read all images into memory
List<System.Drawing.Bitmap> images = new List<System.Drawing.Bitmap>();
System.Drawing.Bitmap finalImage = null;
try
{
int width = 0;
int height = 0;
foreach (string image in files)
{
//create a Bitmap from the file and add it to the list
System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(image);
//update the size of the final bitmap
width += bitmap.Width;
height = bitmap.Height > height ? bitmap.Height : height;
images.Add(bitmap);
}
//create a bitmap to hold the combined image
finalImage = new System.Drawing.Bitmap(width, height);
//get a graphics object from the image so we can draw on it
using (System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(finalImage))
{
//set background color
g.Clear(System.Drawing.Color.Black);
//go through each image and draw it on the final image
int offset = 0;
foreach (System.Drawing.Bitmap image in images)
{
g.DrawImage(image,
new System.Drawing.Rectangle(offset, 0, image.Width, image.Height));
offset += image.Width;
}
}
return finalImage;
}
catch (Exception ex)
{
if (finalImage != null)
finalImage.Dispose();
throw ex;
}
finally
{
//clean up memory
foreach (System.Drawing.Bitmap image in images)
{
image.Dispose();
}
}
}
}
尝试
stitchedImage.Save(@"D:\Naved\BasicDotNet\Images\stitchedImage.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
代替
stitchedImage.Save(@"D:\Naved\BasicDotNet\Images", System.Drawing.Imaging.ImageFormat.Jpeg);
Image.Save (String, ImageFormat)
的第一个参数是要保存到的文件名 ,而不是要保存到的目录 。 以前你做过
string[] files = Directory.GetFiles(@"D:\Naved\BasicDotNet\Images");
因此@"D:\\Naved\\BasicDotNet\\Images"
必须是目录,而不是文件。
(顺便说一句,我建议将缝合的图像保存到其他目录中;否则,每次运行代码时,您都会将先前的缝合和先前的内容缝合在一起。)
stitchedImage.Save(@"D:\Naved\BasicDotNet\Images", System.Drawing.Imaging.ImageFormat.Jpeg); - you need to specify the file name here. I.e edit it to something like this: `stitchedImage.Save(@"D:\Naved\BasicDotNet\Images\myjpeg.Jpeg", System.Drawing.Imaging.ImageFormat.Jpeg)`
