使用itextsharp的图像 [英] images using itextsharp

问题描述

大家好，

我正在使用 itextsharp 将Gridview保存为PDF文件。

我在Gridview之前有3行显示（gridview的标识，地址和标题）。这是我的aspx代码：

Hi all,
I'm using itextsharp to save Gridview to PDF file.
I have 3 lines before the Gridview to display (the logo, address and title of the gridview). here is my aspx code:

<asp:Panel runat="server" ID="PaidOrdersPanel">
<!-- to be shown on PDF-->
<img src="http://dev.123.com/img/logo.png" style="width: 249px; height: auto; display: none;" />
<span style="color: #10598B; font-weight: normal; font-size: 12px !important; display: none; font-family: Corbel;" id="h9">123 Inc.<br />
123 St.<br />
city<br />
postal code</span>
<h5 style="color: #10598B; display: none; text-align: center;">Paid orders report</h5>
<asp:GridView runat="server" ID="PaidOrdersGV" RowStyle-Wrap="false" AllowPaging="true" PageSize="10" Width="100%" CssClass="Grid" AlternatingRowStyle-CssClass="alt" AutoGenerateColumns="false"

    PagerStyle-CssClass="pgr" HeaderStyle-ForeColor="White" PagerStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" RowStyle-HorizontalAlign="Center" DataKeyNames="Document#"

     OnPageIndexChanging="PaidOrdersGV_PageIndexChanging" OnRowDataBound="PaidOrdersGV_RowDataBound" OnRowCommand="PaidOrdersGV_RowCommand">
    <EmptyDataTemplate>
     <div style="text-align: center;">no records found</div>
     </EmptyDataTemplate>
     <Columns>
     <asp:ButtonField CommandName="PaidOrders_Details" DataTextField="Document#" HeaderText="Document #" SortExpression="Document#" ItemStyle-ForeColor="Black" ItemStyle-Font-Underline="true" />
    <asp:BoundField DataField="Order#" HeaderText="order #" SortExpression="Order#" />
     <asp:BoundField DataField="Order Date" HeaderText="Order Date" SortExpression="Order Date" DataFormatString="{0:d}"></asp:BoundField>
    <asp:BoundField DataField="Status" HeaderText="Status" SortExpression="Status"></asp:BoundField>
     <asp:BoundField DataField="Amount" HeaderText="Amount" SortExpression="Amount" DataFormatString="{0:C2}"></asp:BoundField>
     </Columns>
</asp:GridView>
</asp:Panel>

和C＃代码：

and C# code:

if (PaidOrdersGV.Rows.Count > 0)
            {
                //to allow paging=false & change style.
                PaidOrdersGV.HeaderStyle.ForeColor = System.Drawing.Color.Black;
                PaidOrdersGV.BorderColor = Color.Gray;
                PaidOrdersGV.Font.Name = "Tahoma";
                PaidOrdersGV.DataSource = clsBP.get_PaidOrders(lbl_BP_Id.Text);
                PaidOrdersGV.AllowPaging = false;
                PaidOrdersGV.Columns[0].Visible = false;
                PaidOrdersGV.DataBind();

                //to PDF code 
                string attachment = "attachment; filename=myFile.pdf";
                Response.ClearContent();
                Response.AddHeader("content-disposition", attachment);
                Response.ContentType = "application/pdf";
                StringWriter stw = new StringWriter();
                HtmlTextWriter htextw = new HtmlTextWriter(stw);
                htextw.AddStyleAttribute("font-size", "8pt");
                htextw.AddStyleAttribute("color", "Grey");

                PaidOrdersPanel.RenderControl(htextw);//Name of the Panel
                Document document = new Document();
                document = new Document(PageSize.A4, 5, 5, 15, 5);
                FontFactory.GetFont("Tahoma", 50, iTextSharp.text.BaseColor.BLUE);
                PdfWriter.GetInstance(document, Response.OutputStream);
                document.Open();

                StringReader str = new StringReader(stw.ToString());
                HTMLWorker htmlworker = new HTMLWorker(document);
                htmlworker.Parse(str);

                document.Close();
                Response.Write(document);
            }

PDF已创建，但图片未显示在文件中+所有CSS（颜色，字体..等等不适用）。



我错过了一些东西吗？



请指教



提前感谢

the PDF is created but the image is not shown in the file + all CSS (colors, fonts .. etc is not applied).

am I missing some thing?

please advise

thanks in advance

推荐答案

我解决了图像和CSS样式的问题。

itextSharp喜欢旧的HTML标签，例如

I have solved the problem of images and CSS style.
itextSharp likes the old HTML tags like

<table></table>

当我将所有HTML代码放在一个表格中时，一切都像魅力

请把你所有的CSS 内联



PS我使用过最新的dll 5.5



谢谢大家的帮助:)！

when i placed all my HTML code inside a table, everything worked like charm
please put all your CSS inline

P.S. I have used the latest dll 5.5

thank you all for your help :) !

尝试使用其他的不同的.dll来源。

有很多版本的itextsharp dll有些有这个bug。

try with diffrent .dll from other sources.
there are many versions of itextsharp dll some having that bug.
