Hi,
I’m using Aspose.PDF with docker and kubernetes. While it is working, on my local computer, it is not working in the docker environment.

This is the exception that i get:

System.OutOfMemoryException: Out of memory.

@asifefer

Would you kindly provide your docker environment details along with sample source PDF and complete sample code snippet. We will test the scenario in our environment and address it accordingly.

This is the problematic PDF:

failurepdf (2).pdf (84.3 KB)

And this is the docker file:

http://sendanywhe.re/487NLNLH

@asifefer

Would you please also share the code snippet that you are using. Please make sure to use latest version of the API as well before sharing the code snippet with us.

The code works for most of the PDF files. But for some of them i got this error message. So, this is the code snippet that i’m using. Pay attention that the function is getting the pdf as base64:

    [HttpPost]
    [Route("ConvertToHtml")]
    public async Task<ActionResult<object>> ConvertToHtml()
    {
        Console.WriteLine("****: Start PDF ConvertToHtml()");
        Stopwatch sw = new Stopwatch();
        sw.Start();

        string tmpFileDataBase64 = string.Empty;
        using (StreamReader reader = new StreamReader(Request.Body, Encoding.UTF8))
        {
            tmpFileDataBase64 = await reader.ReadToEndAsync();
        }
        string fileDataBase64 = tmpFileDataBase64.Trim(new char[] {'\"'});

        byte[] fileData = Convert.FromBase64String(fileDataBase64);

        MemoryStream stream = new MemoryStream(fileData);
        var wrdf = new Aspose.Pdf.Document(stream);

        HtmlSaveOptions saveOptions = new HtmlSaveOptions(HtmlDocumentType.Html5);
        saveOptions.FixedLayout = false;

        saveOptions.FlowLayoutParagraphFullWidth = true;
        saveOptions.LettersPositioningMethod = HtmlSaveOptions.LettersPositioningMethods.UseEmUnitsAndCompensationOfRoundingErrorsInCss;
        saveOptions.RemoveEmptyAreasOnTopAndBottom = true;
        saveOptions.TryMergeAdjacentSameBackgroundImages = true;
        saveOptions.TrySaveTextUnderliningAndStrikeoutingInCss = true;
        saveOptions.CustomHtmlSavingStrategy = new HtmlSaveOptions.HtmlPageMarkupSavingStrategy(SavingToStream);

        saveOptions.AntialiasingProcessing = HtmlSaveOptions.AntialiasingProcessingType.TryCorrectResultHtml;
        saveOptions.DocumentType = HtmlDocumentType.Html5;

        using (MemoryStream htmlStream = new MemoryStream())
        {
            wrdf.Save(@"stam.html", saveOptions);
            stream.Close();
        }

        this.HtmlData = Regex.Replace(this.HtmlData, @"<img [\s\S]+? />", "");
        this.HtmlData = Regex.Replace(this.HtmlData, @"font-family:'[\s\S]+?';*", "font-family:'Ariel';");

        var response = new
        {
            statusCode = 200,
            data = this.HtmlData,
        };

        sw.Stop();
        Console.WriteLine("****: End DOCX ConvertToHtml(). Total Running Time = " + sw.ElapsedMilliseconds + " (milisec)");

        return Ok(response);
    }
    private void SavingToStream(HtmlSaveOptions.HtmlPageMarkupSavingInfo htmlSavingInfo)
    {
        byte[] resultHtmlAsBytes = new byte[htmlSavingInfo.ContentStream.Length];
        htmlSavingInfo.ContentStream.Read(resultHtmlAsBytes, 0, resultHtmlAsBytes.Length);
        this.HtmlData = Encoding.UTF8.GetString(resultHtmlAsBytes);
    }
