A Generic Error Occurred In Gdi+. Asp.net C#
occured in GDI+ in Bitmap.Save method up vote 26 down vote favorite 8 I am working on to upload and same a thumnail copy of that image in a thumbnail forder. 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 a generic error occured in gdi+. bitmap.save c# 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(originalBM

Join them; it only takes a minute: Sign up A generic error occurred in GDI+, JPEG Image to MemoryStream up vote 200 down vote favorite 38 This seems to be a bit of an infamous error all over the web. So much so that I have been unable to http://stackoverflow.com/questions/1053052/a-generic-error-occurred-in-gdi-jpeg-image-to-memorystream find an answer to my problem as my scenario doesn't fit. An exception gets thrown when I save the image to the stream. Weirdly this works perfectly with a png but gives the above error with jpg and gif which is rather confusing. Most similar problem out there relate to saving images to files without permissions. Ironically the solution is to use a memory stream as I am doing.... public static byte[] ConvertImageToByteArray(Image imageToConvert) { using (var ms = new MemoryStream()) { ImageFormat format; switch (imageToConvert.MimeType()) { case "image/png": format = ImageFormat.Png; break; case "image/gif": format = ImageFormat.Gif; break; default: format = ImageFormat.Jpeg; break; } imageToConvert.Save(ms, format); return ms.ToArray(); } } More detail to the exception. The reason this causes so many issues is the lack of explanation :( System.Runtime.InteropServices.ExternalException was unhandled by user code Message="A generic error occurred in GDI+."

have a write permission on some directory. For example, if you are trying to save the Image from the memory stream to the file system , you may get that error. I also faced that error when I was using Infragistics charts control , the control was trying to create a temporary chart in ChartImages folder and my application was not given the write permission. Please if you are using XP, make sure to add write permission for the aspnet account on that folder. If you are using windows server (2003,2008) or Vista, make sure that add write permission for the Network service account. Hope it help some one. 23 Comments Na, _one_ of the possible errors could be the one, you described. The "Generic error" in fact is used in certain scenarios. It means "we were to lazy to write better error return code". This really sucks. Uwe - Saturday, February 28, 2009 8:44:55 PM Well, at least that's based on my experience and on the problems i faced. I know that there is many other causes of that problem,but that's what i know until this time. anas - Saturday, February 28, 2009 8:57:28 PM I think it's the most common error so permissions should always be checked first. SGWellens - Saturday, February 28, 2009 9:18:12 PM It might not be that you don't have write permissions, but a sharing violation might be in effect. Common scenario that this happens: 1) Read an image into a Bitmap object 2) Manipulate the bitmap 3) Wanting to write back the bitmap to overwrite the original image file you read in step 1. This can happen because the Bitmap implementation seems to be as lazy as possible. It can choose the just remember the path that was the source of the image bits (or even a handle to the opened file they came from). This then means your software has the original image file open, causing this problem when you try to overwrite it in step three. To work around this use some simple code in an intermediate step (let's say 1a) that creates a new, blank Bitmap object with the same width/height/colordepth as the image you read. Then, get a Graphics object for the blank image and draw (BitBlt, basically) the loaded image onto the blank image. Then, dispose the loaded image. This gets you a Bitmap object that contains the content
