Error in page.Resources.Images.Add(stream) method - Out of memory

Aspose.PDF Product Family

Hello.

I have got a problem. Part of my application converts normal pdf (with text, images…) to scaned pdf (only image on all page).

This is part of my function:

public void ConverAllDocument(string pathToDocument, string pathToOutputDocument)
{
int pageCountInDocument = 0;
using (Document readedPdfDocument = new Document(pathToDocument))
{
pageCountInDocument = readedPdfDocument.Pages.Count;
}

        Dictionary<int, Page> pagesForNewDocument = new Dictionary<int, Page>();

        Parallel.For(1, pageCountInDocument, new ParallelOptions() { MaxDegreeOfParallelism = 100 }, (int pageNumber) =>
        {
            using (Document readedPdfDocument = new Document(pathToDocument))
            {
                Page pageWithOrginalDocument = readedPdfDocument.Pages[pageNumber];

                Document document = new Document();
                Page page = document.Pages.Add();

                if (pageWithOrginalDocument.Rotate == Rotation.on90 || pageWithOrginalDocument.Rotate == Rotation.on270)
                {
                    page.SetPageSize(pageWithOrginalDocument.CropBox.Height, pageWithOrginalDocument.CropBox.Width);
                }
                else
                {
                    page.SetPageSize(pageWithOrginalDocument.CropBox.Width, pageWithOrginalDocument.CropBox.Height);
                }

                using (MemoryStream imageStream = GetPageAsImage(quality, pageWithOrginalDocument, pageWithOrginalDocument))
                {
                    System.Drawing.Image pageAsImage = System.Drawing.Image.FromStream(imageStream);

                    Rectangle rectangleForCreatePage = GetImageRectangle(page, pageAsImage);

                    ChangePageSizeIfNeeded(page, pageAsImage);

                    using (MemoryStream imageStreamWithRotatedImage = RotatePageAsImageIfNeededAndSaveToStream(pageAsImage, page.Rotate))
                    {
                        ConfigurePage(page, rectangleForCreatePage, imageStreamWithRotatedImage);
                    }
                }

                pagesForNewDocument.Add(pageNumber, page);
            }
        });

        using (FileStream fileStream = new FileStream(pathToOutputDocument, FileMode.Open, FileAccess.ReadWrite))
        {
            using (Document newDocument = new Document(fileStream))
            {
                foreach (var page in pagesForNewDocument.OrderBy(x => x.Key))
                {
                    newDocument.Pages.Add(page.Value);
                }

                    newDocument.Save(fileStream);
            }
        }
    }

    private void ConfigurePage(Page page, Rectangle rectangleForCreatePage, MemoryStream imageStreamWithRotatedImage)
    {
        page.Resources.Images.Add(imageStreamWithRotatedImage); **ERROR**
        page.Contents.Add(new GSave());
        Rectangle rectangle = rectangleForCreatePage;
        Matrix matrix = new Matrix(new double[] { rectangle.URX - rectangle.LLX, 0, 0, rectangle.URY - rectangle.LLY, rectangle.LLX, rectangle.LLY });
        page.Contents.Add(new ConcatenateMatrix(matrix));
        XImage ximage = page.Resources.Images[page.Resources.Images.Count];
        page.Contents.Add(new Do(ximage.Name));
        page.Contents.Add(new GRestore());
    }

How can I avoid this error?

@kr75

Can you please share the source PDF file so that we may try to reproduce the same on our end.

This is example document.
TestFile.pdf (745.4 KB)

This situation is random and for me, it occurs most often in Release mode on VS2019, without debug.

@kr75

I request you to share runnable solution as your code contains different missing method calls.

5

AsposeTest.zip (70.3 KB)

This is complete solution. But on production, this code is runs in WPF application.

Maybe you have got better solution on my functionality? I will be grateful for the hints.

I can not reproduce the issue with latest version. Moreover, another approach for adding image to a page is Adding Image Stamp in PDF File.
