Memory not clearing even after disposing presentation object

[InnoviaPro]

Hi There,

We are facing a critical issue, where in spire is holding memory space even after the execution of the code is completed.

Is this something you'll are working on to fix?

So basically i am trying to convert presentation slides into images, so for testing purpose i tried with 4 mb ppt file which took 70 to 80 mb and might be even more to execute this task.
I understand the fact that spire take 10 times more space than the actual ppt size, but issue is when the required task is complete it should have release that memory space, which is not happening at the moment.

Is it something from our end where in we need to manually add some code to clear spire object memory allocation?

Thank You

Hello,

Thanks for your inquiry.
Does your code look like the following? To help us reproduce and solve your memory issue, please provide us with your ppt file and tell us your OS information (e.g. windows10 64bit). You can send it to support@e-iceblue.com or attach it here. Thanks for your assistance in advance.

Code: Select all

  //Create PPT document
            Presentation presentation = new Presentation();

            //Load PPT file from disk
            presentation.LoadFromFile("ToImage.pptx");

            //Save PPT document to images
            for (int i = 0; i < presentation.Slides.Count; i++)
            {
                String fileName = String.Format("ToImage-img-{0}.png", i);
                Image image = presentation.Slides[i].SaveAsImage();
                image.Save(fileName, System.Drawing.Imaging.ImageFormat.Png);
                image.Dispose();
            }
            presentation.Dispose();
        }

My code is somewhat like below

Code: Select all

//Create PPT document
            using(Presentation presentation = new Presentation())
           {

            //Load PPT file from memory stream
            presentation.LoadFromStream(stream, FileFormat.Pptx2013);

            //Save PPT document to images
            for (int i = 0; i < presentation.Slides.Count; i++)
            {
                using (Image image = presentation.Slides[i].SaveAsImage(1920, 1080))
                        {
                            //save the slide to Image
                            using (MemoryStream ms = new())
                            {
                                image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
                                base64OfImage = Convert.ToBase64String(ms.ToArray());
                                //We save this base64 of image as Image s3 bucket
                            }

                        }
            }
        }


I also tried the code u have shared but the impact is same

Hi,

Thank you for providing further info.
I tested your SecondScreenPPT_171_4997_368.pptx file and did reproduce your issue that memory is not clearing after disposing presentation object. There was still 154MB of RAM that has not been cleared after disposing presentation object. I have logged it in our issue tracking system with the ticket SPIREPPT-2153 to let our developers do a deep investigation. We will inform you once there is any update.

For your information the file which i shared is just around 1 MB but we deal with much higher file size , So consider a scenario where in ill upload 100MB File so spire will take around 1GB of space to convert those into images and will hold 700 to 800 MB of memory space or even more.

plz do let me know as early as possible, bcz this package we are using in our production environment and our clients are getting affected by this as well as our server is going out of memory.

Thank You

Hi Amy
Is the same fix added to Spire.Office?
I an using Spire.Office NuGet package which is still showing the 8.1.4 version,
i see that you'll have updated spire presentation with hotfix but what abt spire office?

I can individually download Spire.Presentation because i am also using Spire.Pdf so in order to use both the functionality together one of your team member had advised us to use Spire.Office


Hope I am Clear and soon we will get update for Spire.Office


Thank You

[amy.zhao]

Hi,

Thanks for your feedback.
I have asked test team to build and test a new Spire.Office which includes the fix for SPIREPPT-2153. As Spire.Office is a collection of all products, we need some time to finish all tests for all products and then package them into Spire.Office. We can release a new official version within this month. But we can provide you with a temporary version soon, if you need it, please let me know. Please kindly note that the temporary version is not fully tested and will not be uploaded to NuGet.

Thank you for providing an option of a temporary version but as of now we cant take risk of adding the temporary version of package to our production site.

Will wait for the official Spire.Office NuGet package.
