iTextSharp custom paper size

由 倾然丶 夕夏残阳落幕 提交于 2020-01-02 13:33:10
问题 I'm using iTextsharp library to create PDF files. I can declare for A4 Landscape paper like this: Dim pdfTable As New PdfPTable(9) pdfTable.WidthPercentage = 100 Dim pdfDoc As New Document(PageSize.A4.Rotate()) I'm wondering how I can set Height of pdfTable or A4 Height manually. Because there's a lot more margin left at the bottom, and I need to put some text at that margin. Right now, I put a line of text at the bottom, the line's got pushed to the new page. Q1: How can I override the

iTextSharp 5.5.6.0 Bug? check box tick mark changes

由 守給你的承諾、 提交于 2020-01-02 06:28:13
问题 I have an existing PDF that I am filling in programmatically (C#). There are check boxes on the form. In build 4.4.x they rendered a check mark when selected. In build 5.5.5.0 and 5.5.6.0 they are now a cross symbol. The document has PdfVersion of 54 '6'. I have tried: SetFieldProperty(fieldname, "checkboxtype", RadioCheckField.TYPE_CHECK, null); but with no luck.

实战 iTextSharp

iTextSharp 是用来生成 PDF 的一个组件，在 1998 年夏天的时候，Bruno Lowagie ，iText 的创作者，参与了学校的一个项目，当时使用 HTML 来生成报告，但是，使用 HTML 打印的效果很不理想。最后，他发现，使用 PDF 可以完美解决打印问题，为了能够在各个系统中使用，iText 组件库诞生了。 最初的 iText 主要是支持 Java 語言。之後針對Microsoft .NET C Sharp做了一個版本，也就是我們今天要介紹的 iTextSharp。 目前，iTextSharp 的版本是 5.1.2，下载地址： http://sourceforge.net/projects/itextsharp/files/ 其中主要包含了核心组件：itextsharp.dll 但是，直接使用它并不能处理中文，你还要下载两个组件。 在下载页面中，注意图中标注的 extras 文件夹。 点击之后，可以看到如下的下载： 注意把标注的两个压缩包下载下来，这是使用中文的关键。解开两个压缩之后可以看到下面的两个文件。 iTextAsianCmaps.dll iTextAsian.dll 在创建的项目中，将这三个程序集都添加到项目的引用中。 // 必须先加入资源 BaseFont.AddToResourceSearch("iTextAsian.dll");

问题 I have iTextSharp creating a pdf for me in VB.net. Everything was working famously, except now I want to embed an image. I tried this: Dim test = My.Resources.MyImage Dim logo = Image.GetInstance(test) This an error though: 'GetInstance' cannot be called with these arguments It appears as though it expects a path, and is getting a System.Drawing.Bitmap type.

问题 I need vertical text or just a way to rotate a ColumnText in ITextSharp. (It needs to be absolute position) Until now i have tried a lot of diffrent solution, but with no luck.

问题 I am trying to add a new page to a pdf document, however for some reason this is not happening.

This is the code I have for the adding of new pages: Document doc = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4.Rotate(),20,20,20,40); string rep1Name; // variable to hold the
