setsimplecolumn 不使用 C# 中的 itextsharp 5 将文本定位到 PDF 中的给定坐标

Question

我是 iTextShap 的新手，我正在尝试使用 SetSimpleColumn 添加两个文本列，但不知何故，第二列未定位到给定的 x 坐标。我已经浏览了互联网上的很多内容，并且我正在使用的版本（5.5.13.2）的 iTextSharp 文档并不多。

下面是我写的代码，有什么我遗漏的吗？任何帮助将不胜感激，谢谢！

Font f = new Font(baseFont, 8);

ColumnText ct2 = new ColumnText(writer.DirectContent);
ct2.SetSimpleColumn(29f, 587f, 220f, 100f, 11f, 0);
ct2.AddText(new Paragraph("PATIENT'S NAME:", f));
ct2.AddText(Chunk.NEWLINE);
ct2.AddText(new Paragraph("Street Address:", f));
ct2.AddText(Chunk.NEWLINE);
ct2.AddText(new Paragraph("Address 2:", f));
ct2.AddText(Chunk.NEWLINE);
ct2.AddText(new Paragraph("City, State:", f));
ct2.AddText(Chunk.NEWLINE);
ct2.AddText(new Paragraph("Zip Code:", f));
ct2.AddText(Chunk.NEWLINE);
ct2.AddText(new Paragraph("Telephone:", f));
ct2.Go();

ColumnText ct3 = new ColumnText(writer.DirectContent);
ct3.SetSimpleColumn(455.5f, 587f, 220f, 100f, 11f, 2);
ct3.AddText(new Paragraph("PRACTICE:", f) { Alignment = 0});
ct3.AddText(Chunk.NEWLINE);
ct3.AddText(new Paragraph("Street Address:", f));
ct3.AddText(Chunk.NEWLINE);
ct3.AddText(new Paragraph("Address 2:", f));
ct3.AddText(Chunk.NEWLINE);
ct3.AddText(new Paragraph("City, State:", f));
ct3.AddText(Chunk.NEWLINE);
ct3.AddText(new Paragraph("Zip Code:", f));
ct3.AddText(Chunk.NEWLINE);
ct3.AddText(new Paragraph("Telephone:", f));
ct3.AddText(Chunk.NEWLINE);
ct3.AddText(new Paragraph("Fax:", f));
ct3.Go();

Answer 1

显然对SetSimpleColumn 方法的参数存在误解，您似乎假设前四个参数是x, y, width, height。但实际上，它们是x₁, y₁, x₂, y₂。因此，当你这样做时

ct3.SetSimpleColumn(455.5f, 587f, 220f, 100f, 11f, 2);

您使列从x=220 开始并以x=455.5 结束。

你想要的，更有可能是

ct3.SetSimpleColumn(455.5f, 587f, 455.5f + 220f, 587f + 100f, 11f, 2);
