GhostScript unrecoverable error: undefined file name

Trying to figure out how to take a memoryStream and return images using Ghost Script. Here's the code as well as the error I'm getting once I execute rasterizer.Open:
public static System.Drawing.Image PDFToImage(MemoryStream inputMS)
{
GhostscriptRasterizer rasterizer = null;
GhostscriptVersionInfo version = null;
if (Environment.Is64BitProcess)
version = new GhostscriptVersionInfo(
new Version(0, 0, 0), #"C:\Program Files\gs\gs9.20\bin\gswin64.exe",
string.Empty, GhostscriptLicense.GPL);
else
version = new GhostscriptVersionInfo(
new Version(0, 0, 0), #"C:\Program Files (x86)\gs\gs9.20\bin\gswin32.exe",
string.Empty, GhostscriptLicense.GPL);
int dpi = 96;
System.Drawing.Image img = null;
using (rasterizer = new GhostscriptRasterizer())
{
rasterizer.Open(inputMS, version, true);
for (int i = 1; i <= rasterizer.PageCount; i++)
{
using (MemoryStream ms = new MemoryStream())
{
img = rasterizer.GetPage(dpi, dpi, i);
img.Save(ms, ImageFormat.Jpeg);
ms.Close();
}
}
rasterizer.Close();
}
return img;
}

The problem is that you are pointing to exe file instead of dll. When you replace 'gswin64.exe' to 'gsdll64.dll' (a same for 32 bit verion) your code should work.

Well, Ghostscript is telling you it can't open the file '/config:C:\Users\Sean.McNary\ApexRemington\.vs\config\applicationhosts.config' because (not entirely unsurprisingly with such a garbled filename), it can't find the file.
I presume you are using some kind of wrapper around Ghostscript (which is a DLL written in C), because you are apparently using C#, it would help if you were to state what you are using there.
It 'looks like' whatever wrapper you are using, it expects to be given an input filename, and simply passes that to Ghostscript. While it is possible to pass data from memory to Ghostscript, and to have the rendered result returned in memory, you should be aware that if the input is a PDF file you aren't saving anything, because Ghostscript will spool the whole input to a temporary file before processing it You have to seek around a PDF file, so you need to have random access, hence its written out as a file.
You are going to have to debug into your wrapper and see what its doing.

DLL crashes C# application

My colleague and myself wrote a DLL which we're now trying to use in another application. When we use functions from that DLL in our application when using a web cam the app crashes. When we copy and paste the exact same code the application works.
If we are using a image instead of a web cam then it also works with DLL.
We made a new app just to test it and when using that DLL is still doesn't work.
We're really confused because we get different exceptions and we really don't know what's wrong. Are there any general errors that could cause this? Is there a way we could debug this?
Code is as follows:
private glyphRecognizer recognize = new glyphRecognizer();
picturebox1.image = recognize.recognitionStep1_Grayscaling((Bitmap)picturebox1.image);
And for DLL:
public Bitmap recognitionStep1_Grayscaling(Bitmap image)
{
BitmapData data = image.LockBits(new Rectangle(0, 0, image.Width, image.Height), ImageLockMode.ReadOnly, image.PixelFormat);
UnmanagedImage originalImage = new UnmanagedImage(data);
image.UnlockBits(data);
//grayscaling
UnmanagedImage grayImage = null;
if (data.PixelFormat == PixelFormat.Format8bppIndexed)
{
grayImage = originalImage;
}
else
{
grayImage = UnmanagedImage.Create(originalImage.Width, originalImage.Height, PixelFormat.Format8bppIndexed);
Grayscale.CommonAlgorithms.BT709.Apply(originalImage, grayImage);
}
return grayImage.ToManagedImage();
}

A Generic error occurred in GDI+ in Bitmap.Save method

I am working on to upload and save a thumbnail copy of that image in a thumbnail folder.
I am using following link:
http://weblogs.asp.net/markmcdonnell/archive/2008/03/09/resize-image-before-uploading-to-server.aspx
but
newBMP.Save(directory + "tn_" + filename);
is causing exception "A generic error occurred in GDI+."
I have tried to give permission on folder, also tried to use a new separate bmp object when saving.
Edit:
protected void ResizeAndSave(PropBannerImage objPropBannerImage)
{
// Create a bitmap of the content of the fileUpload control in memory
Bitmap originalBMP = new Bitmap(fuImage.FileContent);
// Calculate the new image dimensions
int origWidth = originalBMP.Width;
int origHeight = originalBMP.Height;
int sngRatio = origWidth / origHeight;
int thumbWidth = 100;
int thumbHeight = thumbWidth / sngRatio;
int bannerWidth = 100;
int bannerHeight = bannerWidth / sngRatio;
// Create a new bitmap which will hold the previous resized bitmap
Bitmap thumbBMP = new Bitmap(originalBMP, thumbWidth, thumbHeight);
Bitmap bannerBMP = new Bitmap(originalBMP, bannerWidth, bannerHeight);
// Create a graphic based on the new bitmap
Graphics oGraphics = Graphics.FromImage(thumbBMP);
// Set the properties for the new graphic file
oGraphics.SmoothingMode = SmoothingMode.AntiAlias; oGraphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
// Draw the new graphic based on the resized bitmap
oGraphics.DrawImage(originalBMP, 0, 0, thumbWidth, thumbHeight);
Bitmap newBitmap = new Bitmap(thumbBMP);
thumbBMP.Dispose();
thumbBMP = null;
// Save the new graphic file to the server
newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
oGraphics = Graphics.FromImage(bannerBMP);
// Set the properties for the new graphic file
oGraphics.SmoothingMode = SmoothingMode.AntiAlias; oGraphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
// Draw the new graphic based on the resized bitmap
oGraphics.DrawImage(originalBMP, 0, 0, bannerWidth, bannerHeight);
// Save the new graphic file to the server
bannerBMP.Save("~/image/" + objPropBannerImage.ImageId + ".jpg");
// Once finished with the bitmap objects, we deallocate them.
originalBMP.Dispose();
bannerBMP.Dispose();
oGraphics.Dispose();
}

When either a Bitmap object or an Image object is constructed from a
file, the file remains locked for the lifetime of the object. As a
result, you cannot change an image and save it back to the same file
where it originated.

A generic error occurred in GDI+, JPEG Image to MemoryStream
Image.Save(..) throws a GDI+ exception because the memory stream is closed
http://alperguc.blogspot.in/2008/11/c-generic-error-occurred-in-gdi.html
EDIT:
just writing from memory...
save to an 'intermediary' memory stream, that should work
e.g. try this one - replace
Bitmap newBitmap = new Bitmap(thumbBMP);
thumbBMP.Dispose();
thumbBMP = null;
newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
with something like:
string outputFileName = "...";
using (MemoryStream memory = new MemoryStream())
{
using (FileStream fs = new FileStream(outputFileName, FileMode.Create, FileAccess.ReadWrite))
{
thumbBMP.Save(memory, ImageFormat.Jpeg);
byte[] bytes = memory.ToArray();
fs.Write(bytes, 0, bytes.Length);
}
}

This error message is displayed if the path you pass to Bitmap.Save() is invalid (folder doesn't exist etc).

// Once finished with the bitmap objects, we deallocate them.
originalBMP.Dispose();
bannerBMP.Dispose();
oGraphics.Dispose();
This is a programming style that you'll regret sooner or later. Sooner is knocking on the door, you forgot one. You are not disposing newBitmap. Which keeps a lock on the file until the garbage collector runs. If it doesn't run then the second time you try to save to the same file you'll get the klaboom. GDI+ exceptions are too miserable to give a good diagnostic so serious head-scratching ensues. Beyond the thousands of googlable posts that mention this mistake.
Always favor using the using statement. Which never forgets to dispose an object, even if the code throws an exception.
using (var newBitmap = new Bitmap(thumbBMP)) {
newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
}
Albeit that it is very unclear why you even create a new bitmap, saving thumbBMP should already be good enough. Anyhoo, give the rest of your disposable objects the same using love.

In my case the bitmap image file already existed in the system drive, so my app threw the error "A Generic error occured in GDI+".
Verify that the destination folder exists
Verify that there isn't already a file with the same name in the destination folder

Check your folder's permission where the image is saved
Right cLick on folder then go :
Properties > Security > Edit > Add-- select "everyone" and check Allow "Full Control"

I was facing the same issue A generic error occurred in GDI+ on saving while working on MVC app, I was getting this error because I was writing wrong path to save image, I corrected saving path and it worked fine for me.
img1.Save(Server.MapPath("/Upload/test.png", System.Drawing.Imaging.ImageFormat.Png);
--Above code need one change, as you need to put close brackets on Server.MapPath() method after writing its param.
Like this-
img1.Save(Server.MapPath("/Upload/test.png"), System.Drawing.Imaging.ImageFormat.Png);

GDI+ exceptions occured due to below points
Folder access issue
Missing properties of images
If folder issue - please provide access to application
If Missing properties then use below code
Code 1
using (Bitmap bmp = new Bitmap(webStream))
{
using (Bitmap newImage = new Bitmap(bmp))
{
newImage.Save("c:\temp\test.jpg", ImageFormat.Jpeg);
}
}
Code 2
using (Bitmap bmp = new Bitmap(webStream))
{
using (Bitmap newImage = new Bitmap(bmp))
{
newImage.SetResolution(bmp.HorizontalResolution, bmp.VerticalResolution);
Rectangle lockedRect = new Rectangle(0, 0, bmp.Width, bmp.Height);
BitmapData bmpData = newImage.LockBits(lockedRect, ImageLockMode.ReadWrite, bmp.PixelFormat);
bmpData.PixelFormat = bmp.PixelFormat;
newImage.UnlockBits(bmpData);
using (Graphics gr = Graphics.FromImage(newImage))
{
gr.SmoothingMode = SmoothingMode.HighQuality;
gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
}
foreach (var item in bmp.PropertyItems)
{
newImage.SetPropertyItem(item);
}
newImage.Save("c:\temp\test.jpg", ImageFormat.Jpeg);
}
}
Different between code 1 and code 2
Code - 1 : it will just create image and can open it on normal image viewer
the image can't open in Photoshop
Image size will be double
Code - 2 : to open image in image edition tools use code
by using code 1 it just create images but it not assign image marks.

I always check/test these:
Does the path + filename contain illegal characters for the given filesystem?
Does the file already exist? (Bad)
Does the path already exist? (Good)
If the path is relative: am I expecting it in the right parent directory (mostly bin/Debug ;-) )?
Is the path writable for the program and as which user does it run? (Services can be tricky here!)
Does the full path really, really not contain illegal chars? (some unicode chars are close to invisible)
I never had any problems with Bitmap.Save() apart from this list.

I had a different issue with the same exception.
In short:
Make sure that the Bitmap's object Stream is not being disposed before calling .Save .
Full story:
There was a method that returned a Bitmap object, built from a MemoryStream in the following way:
private Bitmap getImage(byte[] imageBinaryData){
.
.
.
Bitmap image;
using (var stream = new MemoryStream(imageBinaryData))
{
image = new Bitmap(stream);
}
return image;
}
then someone used the returned image to save it as a file
image.Save(path);
The problem was that the original stream was already disposed when trying to save the image, throwing the GDI+ exeption.
A fix to this problem was to return the Bitmap without disposing the stream itself but the returned Bitmap object.
private Bitmap getImage(byte[] imageBinaryData){
.
.
.
Bitmap image;
var stream = new MemoryStream(imageBinaryData))
image = new Bitmap(stream);
return image;
}
then:
using (var image = getImage(binData))
{
image.Save(path);
}

I got it working using FileStream, get help from these
http://alperguc.blogspot.in/2008/11/c-generic-error-occurred-in-gdi.html

System.Drawing.Image imageToBeResized = System.Drawing.Image.FromStream(fuImage.PostedFile.InputStream);
int imageHeight = imageToBeResized.Height;
int imageWidth = imageToBeResized.Width;
int maxHeight = 240;
int maxWidth = 320;
imageHeight = (imageHeight * maxWidth) / imageWidth;
imageWidth = maxWidth;
if (imageHeight > maxHeight)
{
imageWidth = (imageWidth * maxHeight) / imageHeight;
imageHeight = maxHeight;
}
Bitmap bitmap = new Bitmap(imageToBeResized, imageWidth, imageHeight);
System.IO.MemoryStream stream = new MemoryStream();
bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
stream.Position = 0;
byte[] image = new byte[stream.Length + 1];
stream.Read(image, 0, image.Length);
System.IO.FileStream fs
= new System.IO.FileStream(Server.MapPath("~/image/a.jpg"), System.IO.FileMode.Create
, System.IO.FileAccess.ReadWrite);
fs.Write(image, 0, image.Length);

For me it was a permission problem. Somebody removed write permissions on the folder for the user account under which the application was running.

Create folder path image/thumbs on your hard disk => Problem solved!

I used below logic while saving a .png format. This is to ensure the file is already existing or not.. if exist then saving it by adding 1 in the filename
Bitmap btImage = new Bitmap("D:\\Oldfoldername\\filename.png");
string path="D:\\Newfoldername\\filename.png";
int Count=0;
if (System.IO.File.Exists(path))
{
do
{
path = "D:\\Newfoldername\\filename"+"_"+ ++Count + ".png";
} while (System.IO.File.Exists(path));
}
btImage.Save(path, System.Drawing.Imaging.ImageFormat.Png);

I encountered this error while trying to convert Tiff images to Jpeg. For me the issue stemmed from the tiff dimensions being too large. Anything up to around 62000 pixels was fine, anything above this size produced the error.

for me it was a path issue when saving the image.
int count = Directory.EnumerateFiles(System.Web.HttpContext.Current.Server.MapPath("~/images/savedimages"), "*").Count();
var img = Base64ToImage(imgRaw);
string path = "images/savedimages/upImages" + (count + 1) + ".png";
img.Save(Path.Combine(System.Web.HttpContext.Current.Server.MapPath(path)));
return path;
So I fixed it by adding the following forward slash
String path = "images/savedimages....
should be
String path = "/images/savedimages....
Hope that helps anyone stuck!

from msdn: public void Save (string filename); which is quite surprising to me because we dont just have to pass in the filename, we have to pass the filename along with the path for example: MyDirectory/MyImage.jpeg, here MyImage.jpeg does not actually exist yet, but our file will be saved with this name.
Another important point here is that if you are using Save() in a web application then use Server.MapPath() along with it which basically just returns the physical path for the virtual path which is passed in. Something like: image.Save(Server.MapPath("~/images/im111.jpeg"));

I use this solution
int G = 0;
private void toolStripMenuItem17_Click(object sender, EventArgs e)
{
Directory.CreateDirectory("picture");// هذه العملية للرسم بدون ان يحذف بقية الرسومات
G = G + 1;
FormScreen();
memoryImage1.Save("picture\\picture" + G.ToString() + ".jpg");
pictureBox1.Image = Image.FromFile("picture\\picture" + G.ToString() + ".jpg");
}

The code below solved my problem
pictureBox1.Image=myImage;
Bitmap bmp = new Bitmap(pictureBox1.Image);
bmp.Save("C:\\Users/super/Desktop/robin.jpg");

BinaryFormatter.Serialize( Image ) - ExternalException - A generic error occurred in GDI+

When I try to Serialize some images using the BinaryFormatter, I'll get a ExternalException - A generic error occurred in GDI+." After scratching my head for awhile, I decided to create a simple test project to narrow down the problem:
static void Main(string[] args)
{
string file = #"C:\temp\delme.jpg";
//Image i = new Bitmap(file);
//using(FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read))
byte[] data = File.ReadAllBytes(file);
using(MemoryStream originalms = new MemoryStream(data))
{
using (Image i = Image.FromStream(originalms))
{
BinaryFormatter bf = new BinaryFormatter();
using (MemoryStream ms = new MemoryStream())
{
// Throws ExternalException on Windows 7, not Windows XP
bf.Serialize(ms, i);
}
}
}
}
For specific images, I've tried all sorts of ways of loading the image and I could not get it to work under Windows 7, even when running the program as Administrator.
I've copied the exact same executable and image into my Windows XP VMWare instance and I have no problems.
Anyone have any idea of why for some images it doesn't work under Windows 7, but works under XP?
Here's one of the images:
http://www.2shared.com/file/7wAXL88i/SO_testimage.html
delme.jpg md5: 3d7e832db108de35400edc28142a8281

As the OP pointed out, the code provided throws an exception that seems to be occurring only with the image he provided but works fine with other images on my machine.
Option 1
static void Main(string[] args)
{
string file = #"C:\Users\Public\Pictures\delme.jpg";
byte[] data = File.ReadAllBytes(file);
using (MemoryStream originalms = new MemoryStream(data))
{
using (Image i = Image.FromStream(originalms))
{
BinaryFormatter bf = new BinaryFormatter();
using (MemoryStream ms = new MemoryStream())
{
// Throws ExternalException on Windows 7, not Windows XP
//bf.Serialize(ms, i);
i.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); // Works
i.Save(ms, System.Drawing.Imaging.ImageFormat.Png); // Works
i.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); // Fails
}
}
}
}
It could be that the image in question was created with a tool that added some additional information that is interfering with the JPEG serialization.
P.S. The image can be saved to memory stream using BMP or PNG format. If changing the format is an option, then you can try out either of these or any other format defined in ImageFormat.
Option 2
If your goal is just to get the contents of the image file into a memory stream, then doing just the following would help
static void Main(string[] args)
{
string file = #"C:\Users\Public\Pictures\delme.jpg";
using (FileStream fileStream = File.OpenRead(file))
{
MemoryStream memStream = new MemoryStream();
memStream.SetLength(fileStream.Length);
fileStream.Read(memStream.GetBuffer(), 0, (int)fileStream.Length);
}
}

Although the Bitmap class is marked as [Serializable], it does not actually support serialisation. The best you can do is serialise the byte[] containing the raw image data and then re-create it using a MemoryStream and the Image.FromStream() method.
I can't explain the inconsistent behaviour you're experiencing; for me, it fails unconditionally (although I first discovered this when trying to marshal images between different app domains, rather than manually serialising them).

I don't know for sure but I would lean towards different security models for XP vs Windows 7. Image inherits from System.MarshalByRefObject. There is probably proxying going on between application domains when serialization is performed. This proxying might be forbidden in Windows 7.

Image.Save(..) throws a GDI+ exception because the memory stream is closed

i've got some binary data which i want to save as an image. When i try to save the image, it throws an exception if the memory stream used to create the image, was closed before the save. The reason i do this is because i'm dynamically creating images and as such .. i need to use a memory stream.
this is the code:
[TestMethod]
public void TestMethod1()
{
// Grab the binary data.
byte[] data = File.ReadAllBytes("Chick.jpg");
// Read in the data but do not close, before using the stream.
Stream originalBinaryDataStream = new MemoryStream(data);
Bitmap image = new Bitmap(originalBinaryDataStream);
image.Save(#"c:\test.jpg");
originalBinaryDataStream.Dispose();
// Now lets use a nice dispose, etc...
Bitmap2 image2;
using (Stream originalBinaryDataStream2 = new MemoryStream(data))
{
image2 = new Bitmap(originalBinaryDataStream2);
}
image2.Save(#"C:\temp\pewpew.jpg"); // This throws the GDI+ exception.
}
Does anyone have any suggestions to how i could save an image with the stream closed? I cannot rely on the developers to remember to close the stream after the image is saved. In fact, the developer would have NO IDEA that the image was generated using a memory stream (because it happens in some other code, elsewhere).
I'm really confused :(

As it's a MemoryStream, you really don't need to close the stream - nothing bad will happen if you don't, although obviously it's good practice to dispose anything that's disposable anyway. (See this question for more on this.)
However, you should be disposing the Bitmap - and that will close the stream for you. Basically once you give the Bitmap constructor a stream, it "owns" the stream and you shouldn't close it. As the docs for that constructor say:
You must keep the stream open for the
lifetime of the Bitmap.
I can't find any docs promising to close the stream when you dispose the bitmap, but you should be able to verify that fairly easily.

A generic error occurred in GDI+.
May also result from incorrect save path!
Took me half a day to notice that.
So make sure that you have double checked the path to save the image as well.

Perhaps it is worth mentioning that if the C:\Temp directory does not exist, it will also throw this exception even if your stream is still existent.

Copy the Bitmap. You have to keep the stream open for the lifetime of the bitmap.
When drawing an image: System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI
public static Image ToImage(this byte[] bytes)
{
using (var stream = new MemoryStream(bytes))
using (var image = Image.FromStream(stream, false, true))
{
return new Bitmap(image);
}
}
[Test]
public void ShouldCreateImageThatCanBeSavedWithoutOpenStream()
{
var imageBytes = File.ReadAllBytes("bitmap.bmp");
var image = imageBytes.ToImage();
image.Save("output.bmp");
}

I had the same problem but actually the cause was that the application didn't have permission to save files on C. When I changed to "D:\.." the picture has been saved.

You can try to create another copy of bitmap:
using (var memoryStream = new MemoryStream())
{
// write to memory stream here
memoryStream.Position = 0;
using (var bitmap = new Bitmap(memoryStream))
{
var bitmap2 = new Bitmap(bitmap);
return bitmap2;
}
}

This error occurred to me when I was trying from Citrix. The image folder was set to C:\ in the server, for which I do not have privilege. Once the image folder was moved to a shared drive, the error was gone.

A generic error occurred in GDI+. It can occur because of image storing paths issues,I got this error because my storing path is too long, I fixed this by first storing the image in a shortest path and move it to the correct location with long path handling techniques.

I was getting this error, because the automated test I was executing, was trying to store snapshots into a folder that didn't exist. After I created the folder, the error resolved

One strange solution which made my code to work.
Open the image in paint and save it as a new file with same format(.jpg). Now try with this new file and it works. It clearly explains you that the file might be corrupted in someway.
This can help only if your code has every other bugs fixed

It has also appeared with me when I was trying to save an image into path
C:\Program Files (x86)\some_directory
and the .exe wasn't executed to run as administrator, I hope this may help someone who has same issue too.

For me the code below crashed with A generic error occurred in GDI+on the line which Saves to a MemoryStream. The code was running on a web server and I resolved it by stopping and starting the Application Pool that was running the site.
Must have been some internal error in GDI+
private static string GetThumbnailImageAsBase64String(string path)
{
if (path == null || !File.Exists(path))
{
var log = ContainerResolver.Container.GetInstance<ILog>();
log.Info($"No file was found at path: {path}");
return null;
}
var width = LibraryItemFileSettings.Instance.ThumbnailImageWidth;
using (var image = Image.FromFile(path))
{
using (var thumbnail = image.GetThumbnailImage(width, width * image.Height / image.Width, null, IntPtr.Zero))
{
using (var memoryStream = new MemoryStream())
{
thumbnail.Save(memoryStream, ImageFormat.Png); // <= crash here
var bytes = new byte[memoryStream.Length];
memoryStream.Position = 0;
memoryStream.Read(bytes, 0, bytes.Length);
return Convert.ToBase64String(bytes, 0, bytes.Length);
}
}
}
}

I came across this error when I was trying a simple image editing in a WPF app.
Setting an Image element's Source to the bitmap prevents file saving.
Even setting Source=null doesn't seem to release the file.
Now I just never use the image as the Source of Image element, so I can overwrite after editing!
EDIT
After hearing about the CacheOption property(Thanks to #Nyerguds) I found the solution:
So instead of using the Bitmap constructor I must set the Uri after setting CacheOption BitmapCacheOption.OnLoad.(Image1 below is the Wpf Image element)
Instead of
Image1.Source = new BitmapImage(new Uri(filepath));
Use:
var image = new BitmapImage();
image.BeginInit();
image.CreateOptions = BitmapCreateOptions.IgnoreImageCache;
image.CacheOption = BitmapCacheOption.OnLoad;
image.UriSource = new Uri(filepath);
image.EndInit();
Image1.Source = image;
See this: WPF Image Caching

Try this code:
static void Main(string[] args)
{
byte[] data = null;
string fullPath = #"c:\testimage.jpg";
using (MemoryStream ms = new MemoryStream())
using (Bitmap tmp = (Bitmap)Bitmap.FromFile(fullPath))
using (Bitmap bm = new Bitmap(tmp))
{
bm.SetResolution(96, 96);
using (EncoderParameters eps = new EncoderParameters(1))
{
eps.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 100L);
bm.Save(ms, GetEncoderInfo("image/jpeg"), eps);
}
data = ms.ToArray();
}
File.WriteAllBytes(fullPath, data);
}
private static ImageCodecInfo GetEncoderInfo(string mimeType)
{
ImageCodecInfo[] encoders = ImageCodecInfo.GetImageEncoders();
for (int j = 0; j < encoders.Length; ++j)
{
if (String.Equals(encoders[j].MimeType, mimeType, StringComparison.InvariantCultureIgnoreCase))
return encoders[j];
}
return null;
}

I used imageprocessor to resize images and one day I got "A generic error occurred in GDI+" exception.
After looked up a while I tried to recycle the application pool and bingo it works. So I note it here, hope it help ;)
Cheers

I was getting this error today on a server when the same code worked fine locally and on our DEV server but not on PRODUCTION. Rebooting the server resolved it.
