StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
bind_Data();
this.Page.RenderControl(hw);

StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4.Rotate(), 10f, 10f, 100f, 0f);
//here i need to set Pagesize as Envelope.
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();

i googled it but i couldn't find Envelope size.How do i set the page size as Envelope ,Landscape in dynamically

在此先感谢

推荐答案

您正在创建横向格式的文件A4这一行：

You are creating an A4 document in landscape format with this line:

Document pdfDoc = new Document(PageSize.A4.Rotate(), 10f, 10f, 100f, 0f);

如果您要创建信封格式的文档，你不应该创建一张A4纸，而不是你应该这样做：

If you want to create a document in envelope format, you shouldn't create an A4 page, instead you should do this:

Document pdfDoc = new Document(envelope, 10f, 10f, 100f, 0f);

在这一行，信封是类型的对象长方形。

In this line, envelope is an object of type Rectangle.

有没有这样的事情在信封尺寸。有不同的信封尺寸可供选择：

There is no such thing as the envelope size. There are different envelope sizes to choose from: http://www.paper-papers.com/envelope-size-chart.html

举例来说，如果你想用的，那么你需要创建一个3.5英寸的衡量6的矩形。在PDF中的测量系统不使用英寸，但用户的单位。默认情况下，1用户单位= 1点，1英寸= 72点。

For instance, if you want to create a page with the size of a 6-1/4 Commercial Envelope, then you need to create a rectangle that measures 6 by 3.5 inch. The measurement system in PDF doesn't use inches, but user units. By default, 1 user unit = 1 point, and 1 inch = 72 points.

因此​​，你会这样定义信封变量：

Hence you'd define the envelope variable like this:

Rectangle envelope = new Rectangle(432, 252);

由于：

6 inch x 72 points = 432 points (the width)
3.5 inch x 252 points = 252 points (the height)

如果你想有一个不同的信封类型，你必须做的数学与信封格式的尺寸。

If you want a different envelope type, you have to do the Math with the dimensions of that envelope format.
