I then closed the viewer and after I advanced to the next line and get the error, I can no longer view the image with the Windows viewer. I placed a Breakpoint just prior to the lines producing the error and I am able to open the image file using the Windows image viewer. System.UnaurthorizedAccessException: 'Access to the path 'E:\DCIM\100Canon\dsc_7218.jpg' is denied. System.OutOfMemoryException: 'Out of Memory' I tried both the commented out line using Image.FromFile() as well as the line using FileStream().

So, when I passed in 400 as the argument for the crop, it was trying to crop a 399px wide image with a 400px width bmp and it threw the out of memory error! The resized calculations were making the actual dimensions of the image come out to be like 399 rather than 400 that I passed in. Turns out, what was happening inside the resizer was throwing errors in the crop function. I kept getting errors on the crop part, the resizer worked fine! Img = ImageHandler.CropImage(img, new Rectangle(0, 25, 400, 250)) Image img = ImageHandler.ResizeImage(img, new Size(400, 300)) Then this is how I called the above code. private static Image cropImage(Image img, Rectangle cropArea)īitmap bmpCrop = bmpImage.Clone(cropArea, G.DrawImage(imgToResize, 0, 0, destWidth, destHeight) Īnd then this code for the crop. G.InterpolationMode = InterpolationMode.HighQualityBicubic Graphics g = Graphics.FromImage((Image)b) Int destHeight = (int)(sourceHeight * nPercent) īitmap b = new Bitmap(destWidth, destHeight) Int destWidth = (int)(sourceWidth * nPercent) NPercentH = ((float)size.Height / (float)sourceHeight) NPercentW = ((float)size.Width / (float)sourceWidth) private static Image resizeImage(Image imgToResize, Size size) It can also be thrown by native library code when a native allocation cannot be satisfied, such as if swap space is low.I had a similar problem today when I was trying to resize an image and then crop it, what happened is I used this code to resize the image. It may sometimes also means that such error has nothing to do with objects on the heap.Such a memory error also means that a problem has occurred that the user cannot handle, such as a third-party library that caches strings or an application server that doesn't clean up after deploys.The user is doing something wrong, which means the user tries processing high data or holding onto objects for a long time.In Java programming language, the OutOfMemoryError is thrown means that: What is errorĪn error is thrown by the Java Virtual Machine when it finds that not enough memory is left for storing the object in the heap space, and as a result, the JVM throws an error that it is unable to allocate the object because no more space is left for storing it. Thus when a JVM is launched, the size of the Heap space and permgen is set. The JVM architecture is composed of essential tools and libraries, and the space area is divided into two different parts, i.e., Heap space and Permgen (also known as Permanent Generation). It is the Java restriction that a Java application can only use a limited amount of memory. In Java programming language, a user creates an object, and that object gets stored in the heap area of the Java. So, in this section, we are going to discuss the error, about heap space, and how to fix the error. The name of the error itself conveys that it is an out-of-memory error where the JVM throws such error when it cannot allocate an object in the heap memory. ![]()
