Most of the time the code works fine. Typical answers to above issue indicate that certain resources are not being released. Please consider the following before answering:- This specific image is 34KB in size, is a .JPG image. Server is idle and has over 32GB RAM. If I look at properties of this jpg file, using windows explorer, by right-clicking on file, Windows says: 96 dpi and 32 bit depth. BUT, if I open this jpg file using any graphics program (e.g. photoshop), the file properties show as: 72 dpi and 24 bit depth. So, there is a mis-match between what I think file header properties say and what the file actually contains. Further, if I open the jpg file using a graphics program and just re-save without changing anything, the file properties in windows explorer now match/read correct (72 dpi and 24 bit depth); and the file is processed by System.Drawing.Graphics correctly, without throwing exception. Due to my limited knowledge of the subject, I don't know if the file header of an image file can contain different data from actual file contents. Questions: How can I fix this problem? Or how can I tell System.Drawing.Graphics to ignore file header data and just look at actual image file contents? (as all graphics programs such as photoshop appear to do). Thanks! c# .net graphics system.drawing share|improve this question asked Sep 8 '14 at 12:03 Mike 4917 1 how those JPEG files were created ? it looks like formatting of them is not correct somehow.... –Tigran Sep 8 '14 at

The imageFile variable is just a Server.MapPath to the path of the image. I was curious if anyone had experience this issue previously and if they had any ideas what might be causing it? Is it the size of the image perhaps? I can post the code if necessary and any supporting information I http://stackoverflow.com/questions/1108607/out-of-memory-exception-on-system-drawing-image-fromfile have, but would love to hear people's opinions on this one. asp.net image bitmap share|improve this question asked Jul 10 '09 at 9:27 dooburt 1,73852851 Is the image you're trying to load exceptionally large? –RCIX Jul 10 '09 at 9:28 All images are less than ~700kb. –dooburt Jul 10 '09 at 9:55 2 Are you sure the file in question is a valid image file? I have also run into exactly the same situation, but the the file hasn't been able to load in any other program either. –Dan Byström Jul 10 '09 at 9:57 Note: with valid image file I didn't refer to the file type but the content. That is: could the image data be damaged? –Dan Byström Jul 10 '09 at 9:58 1 I danby, thanks for the response. It isn't my image, so I'm having it sent over and will get it checked. The person uploading is particularly incompetent so I'm hoping it is just that! –dooburt Jul 10 '09 at 10:47 | show 2 more comments 9 Answers 9 active oldest votes up vote 32 down vote accepted It's worth knowing that OutOfMemoryException doesn't always really mean it's out of memory - particularly not when dealing with files. I believe it can also happen if you run out of handles for some reason. Are you disposing of all your bitmaps after you're done with them? Does this

In my sample set of 10 I can process 4 before I get an "Out of memory" error. I am running 32bit windows XP pro with the maximum amount of ram installed. I get the error on the line that reads: g.DrawImage(.... Here is the code I am using to resize the image: private Bitmap ResizeBmp(Bitmap bm, int newWidth, int newHeight) { Bitmap newbmp = new Bitmap(newWidth, newHeight); try { Graphics g = Graphics.FromImage((Image)newbmp); try { //this is the line that throws the error g.DrawImage(bm, new Rectangle(0, 0, newWidth, newHeight), 0, 0, bm.Width, bm.Height, GraphicsUnit.Pixel); } catch(Exception ex) { setError(ex.Message, -1); } g.Dispose(); } catch(Exception ex) { setError(ex.Message, -1); } return newbmp; } Why do I get a memory error like this? I have not seen problems with small png images.

At the end of the loop I added a GC.Collect() This seemed to solve the problem. Reply With Quote October 24th, 2008,01:33 PM #4 Mutant_Fruit View Profile View Forum Posts Senior Member Join
