Remove bleed and slug while converting HTML to PDF

Aspose.PDF Product Family

I am trying to convert a HTML document back to PDF and remove margins from the document. My original document has bleed and slug added to it. I need to retain these margins in HTML and remove them when converting back to PDF. I am using the following code, but the background image in the result is stretched and is not positioned correctly. Also not sure if I am calculating the margin correctly.

    public static void ConvertToPdf(string sourcePdfPath, string sourceHtmlPath, string targetPdfPath)
    {
        HtmlLoadOptions htmlOptions = new HtmlLoadOptions(sourceHtmlPath);
        htmlOptions.ExternalResourcesCredentials = System.Net.CredentialCache.DefaultCredentials;

        using (Document originalDocument = new Document(sourcePdfPath))
        {
            Page modelPage = originalDocument.Pages.First();
            htmlOptions.PageInfo.Margin.Left = modelPage.MediaBox.LLX - modelPage.TrimBox.LLX;
            htmlOptions.PageInfo.Margin.Right = modelPage.TrimBox.URX - modelPage.MediaBox.URX;
            htmlOptions.PageInfo.Margin.Top = modelPage.TrimBox.URY - modelPage.MediaBox.URY;
            htmlOptions.PageInfo.Margin.Bottom = modelPage.MediaBox.LLY - modelPage.TrimBox.LLY;

            using (MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(File.ReadAllText(sourceHtmlPath))))
            {
                using (Document newDocument = new Document(stream, htmlOptions))
                {
                    newDocument.Save(targetPdfPath);
                }
            }
        }
    }

Coud you please have a look and point me in the right direction?

Kind regards,

Hi,

Thanks for the fast reply! Attached are my test files:

HTML_test export_slug.zip: The HTML files that I’m using to generate the PDF
ORIGINAL_test export_slug.pdf: The original PDF that was used to create the HTML files (with Aspose)
ISSUE_test export_slug_convert.pdf: The result when I try to convert the HTML files to PDF with the posted code
EXPECTED_test export_slug.pdf: The result that we are expecting, this was created by cropping the ORIGINAL_test export_slug.pdf document with Aspose.

Kind regards,

Hi,

I could not upload the ZIP with HTML files, tried several times with multiple browsers, but it did not stick.

Here is the code I used to generate the HTML files from ‘ORIGINAL_test export_slug.pdf’:

        public static void ToHtml(string sourcePdfPath, string targetHtmlPath)
        {
            HtmlSaveOptions htmlSaveOptions = new HtmlSaveOptions();
            htmlSaveOptions.SplitIntoPages = false;

            using (Document pdfDoc = new Document(sourcePdfPath))
            {
                pdfDoc.Save(targetHtmlPath, htmlSaveOptions);
            }
        }

Kind regards,

Stefaan
