【问题描述】:
我在我们的 WPF 应用程序中使用 ssrs 客户端 rdlc 报告(3 英寸打印机)。 当报告呈现为 .PDF 并将其保存到临时路径,然后打印 PDF 意味着它可以完美运行。 但是当我尝试直接将报表打印到打印机时,报表呈现为图像(MSDN 网站建议的打印代码),但只打印打印机中报表的一半,而且看起来太难看,因为它看起来像拖动。
报告宽度:3.5 英寸
报告高度:7 英寸
请查看我使用的以下代码并提出您的意见。
// RDLC InvoicePrintReport - Report Ready with Data Source and Parameters
Export(InvoicePrintReport);
Print();
//Report Printing Section
private int m_currentPageIndex;
private IList<Stream> m_streams;
private Stream CreateStream(string name, string fileNameExtension, System.Text.Encoding encoding,
string mimeType, bool willSeek)
{
Stream stream = new MemoryStream();
m_streams.Add(stream);
return stream;
}
private void Export(LocalReport report)
{
string deviceInfo = @"<DeviceInfo><OutputFormat>EMF</OutputFormat><PageWidth>3.5in</PageWidth><MarginTop>0.01in</MarginTop><MarginLeft>0.01in</MarginLeft><MarginRight>0.1in</MarginRight><MarginBottom>0.01in</MarginBottom></DeviceInfo>";
Microsoft.Reporting.WinForms.Warning[] warnings;
m_streams = new List<Stream>();
report.Render("Image", deviceInfo, CreateStream, out warnings);
foreach (Stream stream in m_streams) stream.Position = 0;
}
private void Print()
{
if (m_streams == null || m_streams.Count == 0) throw new Exception("Error: no stream to print.");
PrintDocument printDoc = new PrintDocument();
if (!printDoc.PrinterSettings.IsValid)
{
throw new Exception("Error: cannot find the default printer.");
}
else
{
printDoc.PrintPage += new PrintPageEventHandler(PrintPage);
m_currentPageIndex = 0;
//PaperSize pkCustomSize1 = new PaperSize("First custom size", 100, 200);
//printDoc.DefaultPageSettings.PaperSize = pkCustomSize1;
printDoc.Print();
}
}
private void PrintPage(object sender, PrintPageEventArgs ev)
{
System.Drawing.Imaging.Metafile pageImage =
new System.Drawing.Imaging.Metafile(m_streams[m_currentPageIndex]);
// Adjust rectangular area with printer margins.
System.Drawing.Rectangle adjustedRect = new System.Drawing.Rectangle(
ev.PageBounds.Left - (int) ev.PageSettings.HardMarginX,
ev.PageBounds.Top - (int) ev.PageSettings.HardMarginY, ev.PageBounds.Width, ev.PageBounds.Height);
// Draw a white background for the report
ev.Graphics.FillRectangle(System.Drawing.Brushes.White, adjustedRect);
// Draw the report content
ev.Graphics.DrawImage(pageImage, adjustedRect);
// Prepare for the next page. Make sure we haven't hit the end.
m_currentPageIndex++;
ev.HasMorePages = (m_currentPageIndex < m_streams.Count);
}
