如何使用iTextSharp限制PDF页面上段落的宽度?

我想使用iTextSharp将一个段落(将多行自动换行)插入到PDF文档中,但我想将段落的宽度限制在页面的左半部分。我看不到Paragraph类的“width”属性,但肯定有办法做到这一点,stimmt?

假设的答案对我不起作用,因为它使用明显在iTextSharp(C#)中不可用的iText(Java)东西。具体而言(首先,可能会有更多):

ct.setSimpleColumn(myText, 60, 750, document.getPageSize().getWidth()

虽然* Sharp(大写的首字母')有一个“SetSimpleColumn”,但没有“GetPageSize”。

我开始认为我真正需要做的就是按照建议创建一个'无边框表',并在“BestiTextQuestionsOnStackOverflowFull.pdf”中明确指出

这是一种方法 - 一个无边框的单行表,WidthPercentage设置为50,水平对齐发送到左边:

using (var ms = new MemoryStream())
{
    using (var doc = new Document(PageSize.A4, 50, 50, 25, 25))                     {
        //Create a writer that's bound to our PDF abstraction and our stream
        using (var writer = PdfWriter.GetInstance(doc, ms))
        {

            //Open the document for writing
            doc.Open();

            var courier9RedFont = FontFactory.GetFont("Courier", 9, BaseColor.RED);
            var importantNotice = new Paragraph("Sit on a potato pan Otis - if you don't agree that that's the best palindrome ever, I will sic Paladin on you, or at least say, 'All down but nine - set 'em up on the other alley, pard'", courier9RedFont);
            importantNotice.Leading = 0;
            importantNotice.MultipliedLeading = 0.9F; // reduce the width between lines in the paragraph with these two settings

            // Add a single-cell, borderless, left-aligned, half-page, table
            PdfPTable table = new PdfPTable(1);
            PdfPCell cellImportantNote = new PdfPCell(importantNotice);
            cellImportantNote.BorderWidth = PdfPCell.NO_BORDER;
            table.WidthPercentage = 50;
            table.HorizontalAlignment = Element.ALIGN_LEFT;
            table.AddCell(cellImportantNote);
            doc.Add(table);

            doc.Close();
        }
        var bytes = ms.ToArray();
        String PDFTestOutputFileName = String.Format("iTextSharp_{0}.pdf", DateTime.Now.ToShortTimeString());
        PDFTestOutputFileName = PDFTestOutputFileName.Replace(":", "_");
        var testFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), PDFTestOutputFileName);
        File.WriteAllBytes(testFile, bytes);
        MessageBox.Show(String.Format("{0} written", PDFTestOutputFileName));
    }
}
