OutOfMemoryException on large file while burningannotation
OutOfMemoryException on large file while burningannotation
Hi, I have a 160 page TIFF with annotation on 70 pages. When I burn the annotations on all pages, I get the outofmemoryexception.
Any work around?

Re: OutOfMemoryException on large file while burningannotation
Hi,
Page is loaded in the memory when you burn the annotations on image. 70 pages are loaded in the memory when you burn the annotations on 70 images. I think your computer does not have enough memory for storing your images in memory. Please monitor the memory usage and save the burned images to the file for freeing the memory.
Best regards, Alexander

Re: OutOfMemoryException on large file while burningannotation
Hi Alex,
I revised the code like this:
I revised the code like this:
// Part of a method
imageViewer.Images.SaveAsync(saveDialog.FileName, encoder);
imageViewer.Images.ImageSaving += Images_ImageSaving;
// images_ImageSaving callback
private void Images_ImageSaving(object sender, ImageSavingEventArgs e)
{
if (_burnImage)
{
Dispatcher.Invoke(new Action(() =>
{
imageViewer.AnnotationViewController.BurnAnnotationCollectionOnImage(e.Image);
}));
}
}
Should I do it asynchronously or is there something that I can do to release the resources after burn and save?

Hi,
Thank you for information. Could you send us a working project (with data), which allows to reproduce your problem? If yes, please send your project to support@vintasoft.com. If no, please check the memory usage, here is code snippet:

Re: OutOfMemoryException on large file while burningannotation
Hi, here's the memory usage. The TIF file is classified so I can't give it to you. This is a 160 page high res TIF file with annotation on at least 20 pages. This one did not crash. I forgot to mention that the application is 32-bit. 64-bit is not an option because we are still supporting XP in the workplace.
Thanks for your time.

Re: OutOfMemoryException on large file while burningannotation
Hello,
The AnnotationViewController.BurnAnnotationCollectionOnImage method burns annotations on image, for doing this method loads image into the memory. In your code you are burning annotations on each saving image, i.e. you are loading all images with annotations into memory and as a result you can have the OutOfMemoryException when all available memory will be used.
For solving the problem you need burn annotations on image and dispose image when image is not necessary any more.
Here is code that allows to burn annotations on images, save images to a TIFF file and prevent the OutOfMemoryException:

using (Stream stream = File.Create(filePath))
{
for (int i = 0; i < collection.Count; i++)
{
if (controller.GetAnnotationsView(i).Count > 0)
{
using (VintasoftImage image = controller.GetImageWithAnnotations(i))
{
encoder.SaveImage(image, stream);
}
}
else
{
encoder.SaveImage(collection[i], stream);
}
encoder.CreateNewFile = false;
}
}
}
}
