iTextSharp 页脚背景颜色

Question

我正在尝试设置页脚的背景颜色。我似乎找不到任何可以帮助执行此操作的代码。请参阅我的 OnEndPage 事件代码。

我试过cb。SetColorFill(BaseColor.LIGHT_GRAY(;，但这不起作用：/

使用哪个属性或方法向页脚添加背景色？

public override void OnEndPage(iTextSharp.text.pdf.PdfWriter writer, iTextSharp.text.Document document)
{
base.OnEndPage(writer, document);
iTextSharp.text.Font baseFontNormal = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12f, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);
iTextSharp.text.Font baseFontBig = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12f, iTextSharp.text.Font.BOLD, iTextSharp.text.BaseColor.BLACK);
var headerImagePath = System.Web.HttpContext.Current.Server.MapPath("~/Content/misc/proactive-reg-form-header.jpg");
var headerImage = Image.GetInstance(headerImagePath);
if (headerImage.Height > headerImage.Width)
{
//Maximum height is 800 pixels.
float percentage = 0.0f;
percentage = 700 / headerImage.Height;
headerImage.ScalePercent(percentage * 100);
}
else
{
//Maximum width is 600 pixels.
float percentage = 0.0f;
percentage = 572 / headerImage.Width;
headerImage.ScalePercent(percentage * 100);
}
//Create PdfTable object
PdfPTable pdfTab = new PdfPTable(1);
//We will have to create separate cells to include image logo and 2 separate strings
//Row 1
//PdfPCell pdfCell1 = new PdfPCell();
PdfPCell pdfCell2 = new PdfPCell(headerImage);
//PdfPCell pdfCell3 = new PdfPCell();
String text = "Page " + writer.PageNumber + " of ";
//Add paging to footer
{
cb.BeginText();
cb.SetFontAndSize(bf, 10);
cb.SetTextMatrix(document.PageSize.GetRight(100), document.PageSize.GetBottom(30));
cb.ShowText(text);
cb.EndText();
float len = bf.GetWidthPoint(text, 10);
cb.AddTemplate(footerTemplate, document.PageSize.GetRight(100) + len, document.PageSize.GetBottom(30));
//add image to footer
writer.DirectContent.AddImage(footerImage);
}
pdfCell2.HorizontalAlignment = Element.ALIGN_CENTER;
pdfCell2.VerticalAlignment = Element.ALIGN_BOTTOM;
pdfCell2.Border = 0;
pdfTab.AddCell(pdfCell2);
pdfTab.TotalWidth = 100f;
pdfTab.WidthPercentage = 100f;
//call WriteSelectedRows of PdfTable. This writes rows from PdfWriter in PdfTable
//first param is start row. -1 indicates there is no end row and all the rows to be included to write
//Third and fourth param is x and y position to start writing
pdfTab.WriteSelectedRows(0, -1, 10, document.PageSize.Height - 10, writer.DirectContent);
//set pdfContent value
if (document.PageNumber != 1)
{
//Move the pointer and draw line to separate header section from rest of page
cb.MoveTo(10, document.PageSize.Height - 60);
cb.LineTo((document.PageSize.Width - 10), document.PageSize.Height - 60);
cb.Stroke();
}
}

知道了！

所以我修改了以下代码：

//Add paging to footer
{
cb.BeginText();
cb.SetFontAndSize(bf, 10);
cb.SetTextMatrix(document.PageSize.GetRight(100), document.PageSize.GetBottom(30));
cb.ShowText(text);
cb.EndText();
float len = bf.GetWidthPoint(text, 10);
cb.AddTemplate(footerTemplate, document.PageSize.GetRight(100) + len, document.PageSize.GetBottom(30));
//add image to footer
writer.DirectContent.AddImage(footerImage);
}

跟

//Add paging to footer
{
cb.BeginText();
cb.SetFontAndSize(bf, 10);
cb.SetTextMatrix(document.PageSize.GetRight(100), document.PageSize.GetBottom(30));
cb.ShowText(text);
cb.EndText();
float len = bf.GetWidthPoint(text, 10);
cb.AddTemplate(footerTemplate, document.PageSize.GetRight(100) + len, document.PageSize.GetBottom(30));
//this part adds the background color
cb.SetColorFill(BaseColor.LIGHT_GRAY);
cb.Rectangle(0, 0, document.PageSize.Width, 50);
cb.FillStroke();
//add image to footer
writer.DirectContent.AddImage(footerImage);
}
