Resizing PDF using PdfFileEditor produces corrupt PDF

[ejt66]

Hello,

I am resizing pdf’s to normalize their content to all the same paper size, for example, resize a page size from A4 to Letter. For some documents the output is corrupted and returns the following error when you open with acrobat: “there was an error processing an annotation or link. there was a problem reading this document (16)”

Attached is sample input and the output used in the code example below.

string inputFile = @"d:\input\input.pdf";
string outFile = @"d:\output\output.pdf";

            Document doc = new Document(inputFile);
        PdfFileEditor fileEditor = new PdfFileEditor();

        for (int i = 0; i < doc.Pages.Count; i++)
        {
            fileEditor.ResizeContents(doc, new int[] {i + 1},
                PdfFileEditor.ContentsResizeParameters.PageResize(PageSize.PageLetter.Width,
                    PageSize.PageLetter.Height));
        }

        doc.Save(outFile);

Thanks for contacting support.

We have tested the scenario in our environment and managed to replicate the same issue, which you have mentioned. However, when we tried to resize the Pages of document with DOM approach and Aspose.Pdf for .NET 17.12, the output PDF document was fine and no error message was prompted while opening the document in Adobe Reader. Following is the code snippet, which we have tried to test the scenario with DOM model.

string inputFile = dataDir + @"input.pdf";
string outFile = dataDir + @"outputExample_out.pdf";
Document doc = new Document(inputFile);
foreach(Page page in doc.Pages)
{
 page.SetPageSize(PageSize.PageLetter.Width, PageSize.PageLetter.Height);
}
doc.Save(outFile);

For your kind reference, an output PDF document is also attached. Furthermore, we have also logged an issue related to Facades API as PDFNET-43947 in our issue tracking system. We will further investigate the issue in details and keep you updated with the status of its resolution. Meanwhile you may please use DOM approach with latest version of the API, which resolves the issue.

We are sorry for the inconvenience caused.

Thank you for the work around, unfortunately this does not resize the content. What I want to do is take a pdf that has a paper size of A4 and resize the content down to fit into Letter.

Aspose provided the following solution via my paid support request. Hope it helps someone else out in the future:

In case you want to proportionally resize content, please consider using the PdfPageEditor.Zoom:

            double width = PageSize.PageLetter.Width;  //  set page Width
            double height = PageSize.PageLetter.Height;  //  set page Height

            Document doc = new Document("Original Attachment.pdf");
            Aspose.Pdf.Rectangle rect = doc.Pages[1].Rect;
            // isLandscape
            if (rect.Width > rect.Height) {
                double temp = width;
                width = height;
                height = temp;
            }

            double zoomWidth = width / rect.Width;
            double zoomHeight = height / rect.Height;

            PdfPageEditor ppe = new PdfPageEditor();
            ppe.BindPdf(doc);
            ppe.PageSize = new Aspose.Pdf.PageSize((float)width, (float) height);

            ppe.Zoom = (zoomWidth > zoomHeight) ? (float)zoomHeight :  (float)zoomWidth;

            ppe.VerticalAlignmentType = VerticalAlignment.Center;
            ppe.HorizontalAlignment = HorizontalAlignment.Center;

            ppe.Save("Resized with Zoom_PageLetter.pdf");
