basefontpdf_java怎样将网页上面的数据以pdf的格式导出

⑴ C#可以用itextsharp 打开pdf文件吗

itextsharp里封装的都有，你指的打开是要在电脑上展示信息，还是用软件可以读到pdf信息

⑵ android中向储存卡中写入 pdf 文件出错，求解决。。。

File temp = new File(sdCardDir, "HelloWorld.pdf");你不需要指定sdcarddir，直接File temp = new File( "HelloWorld.pdf")就可以了

⑶ itextsharp 可以显示pdf文件吗

⑷ C#如何编写把图片转换为PDF格式的程序

我前两天正好写了这样一个程序：（C#的）
你首先要下载 iTextSharp.dll文件，之后添加到引用中
我给你提供一个类：
public void ExportDataIntoPDF(string pathName, String path)
{//导出至PDF
iTextSharp.text.Document document = new iTextSharp.text.Document();
try
{
iTextSharp .text .pdf .PdfWriter .GetInstance (document, new FileStream(pathName, FileMode.CreateNew ));
document.Open();
iTextSharp.text.pdf.BaseFont bfChinese = iTextSharp.text.pdf.BaseFont.CreateFont("C:\\WINDOWS\\Fonts\\simsun.ttc,1", iTextSharp.text.pdf.BaseFont.IDENTITY_H, iTextSharp.text.pdf.BaseFont.NOT_EMBEDDED);
iTextSharp.text.Font Titlefont = new iTextSharp.text.Font(bfChinese, 16, iTextSharp.text.Font.BOLD , new iTextSharp.text.Color(0, 0, 0));

document.Add(new Paragraph(" 将图片转成PDF：" + "\n", Titlefont));
iTextSharp.text.Image je = iTextSharp.text.Image.GetInstance(path);//path就是函数入参，即你要转成PDF的图片路径
document.Add(je);
}

catch (Exception de)
{
MessageBox .Show (de.ToString());
}
document.Close();
}
你调用这个类就ok了

⑸ c#可以调用什么工具把图片转换成pdf格式或者.swf格式吗如果可以，应该怎么做呢

如果是把图片转换为pdf格式的，使用如下代码:
首先要下载 iTextSharp.dll文件，之后添加到引用中
提供一个类：
public void ExportDataIntoPDF(string pathName, String path)
{//导出至PDF
iTextSharp.text.Document document = new iTextSharp.text.Document();
try
{
iTextSharp .text .pdf .PdfWriter .GetInstance (document, new FileStream(pathName, FileMode.CreateNew ));
document.Open();
iTextSharp.text.pdf.BaseFont bfChinese = iTextSharp.text.pdf.BaseFont.CreateFont("C:\\WINDOWS\\Fonts\\simsun.ttc,1", iTextSharp.text.pdf.BaseFont.IDENTITY_H, iTextSharp.text.pdf.BaseFont.NOT_EMBEDDED);
iTextSharp.text.Font Titlefont = new iTextSharp.text.Font(bfChinese, 16, iTextSharp.text.Font.BOLD , new iTextSharp.text.Color(0, 0, 0));

document.Add(new Paragraph(" 将图片转成PDF：" + "\n", Titlefont));
iTextSharp.text.Image je = iTextSharp.text.Image.GetInstance(path);//path就是函数入参，即你要转成PDF的图片路径
document.Add(je);
}

catch (Exception de)
{
MessageBox .Show (de.ToString());
}
document.Close();
}
调用这个类就ok了

如果转换为swf格式的话就需要使用商业的dll了

⑹ com.lowagie.text.pdf.BaseFont.getCharBBox(C)

不显示中文可能是你设置报表时候，设置动态复选框的时候属性没有设置，出现乱码问题，选择简体中文就可以了（好像是什么chinese什么的来），后面的不显示字段，(如果jar包齐全的情况下)应该是跟数据库字段没有对应吧，注意跟报表里填写的字段要一一对应，大小写都统一!

⑺ java怎样将网页上面的数据以pdf的格式导出,求代码

需要用到一个pdf的jar包，去网上下载一个itextpdf.jar。导出pdf的格式都是需要自己用代码实现的，每一行，每一个列是什么格式，都需要自己写出来，是不能够自动生成的，反正很麻烦。我做的一个导出成pdf特定格式的东西，写了好几千行代码。相当头痛。

table = new PdfPTable(relativeWidths);
table.setWidthPercentage(100);

cell.setColspan(root ? 12 : 10);

cell.setBorder(Rectangle.NO_BORDER);
table.addCell(cell);

}

⑻ 急~急~~急~~~ ASP.NET 怎么讲图片生成PDF文件，求代码

我是借助组件完成导出PDF文件的。在写代码之前，你要下载一个名为iTextSharp的组件，并将其引用到你的程序中。然后将生成的PDF文件通过流形式导出。

代码如下：C#的

stringstrPDF_Nm=DateTime.Now.Year+"-"+DateTime.Now.Month+"-"+DateTime.Now.Day+"-"+DateTime.Now.Hour+"-"+DateTime.Now.Minute+".pdf";
iTextSharp.text.Documentdocument=newDocument();
iTextSharp.text.pdf.PdfWriterpdfwrite=PdfWriter.GetInstance(document,newFileStream(HttpContext.Current.Server.MapPath("~/img_Tmp/"+strPDF_Nm),FileMode.Create));
document.Open();
BaseFontbasefont=BaseFont.CreateFont(@"C:WindowsFontsSTKAITI.TTF",BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);
//解决PDF不能显示中文的关键；创建一个中文楷体的字体对象
iTextSharp.text.Fontfont=newiTextSharp.text.Font(basefont,14);
iTextSharp.text.Tabletable=newiTextSharp.text.Table(4);
iTextSharp.text.Cellcells=newCell(newPhrase("不良报告",font));
cells.Colspan=4;
cells.HorizontalAlignment=1;
table.AddCell(cells);

iTextSharp.text.Imagejpg=iTextSharp.text.Image.GetInstance(Server.MapPath("~/img_Tmp/"+strSavePath));
document.Add(jpg);
document.Add(table);
document.Close();
pdfwrite.Close();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ContentType="application/PDF";
HttpContext.Current.Response.WriteFile(HttpContext.Current.Server.MapPath("~/img_Tmp/"+strPDF_Nm));
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.Close();
