[英]Print FixedDocument with multiple FixedPage in pages per sheet in WPF
我有一个非常简单的WPF应用程序,上面只有一个按钮。
<Button x:Name="btnPrintCard" Grid.Row="2" HorizontalAlignment="Center" Content="Print Card" MinWidth="140" Foreground="White"
Cursor="Hand" Background="#008080" Click="btnPrintCard_Click" />
我正在尝试在“典型A4”页面上打印多张尺寸为3.370 x 2.125的卡片。 如果布置正确,则从左到右的顺序应该每张可容纳10张卡片。 就像adobe reader的打印命令一样,并将每张纸的自定义页面设置为2 x 5。
我正在使用以下代码生成和打印卡:
private void btnPrintCard_Click(object sender, RoutedEventArgs e)
{
try
{
PrintDialog printDialog = new PrintDialog();
bool? pdResult = printDialog.ShowDialog();
if (pdResult != null && pdResult.Value)
{
FixedDocument document = CreateFixedDocument();
printDialog.PrintDocument(document.DocumentPaginator, "ID Card Printing");
}
MessageBox.Show("Printing done.");
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message + " :: " + ex.InnerException);
}
}
private FixedDocument CreateFixedDocument()
{
FixedDocument fixedDocument = new FixedDocument();
// fixedDocument.DocumentPaginator.PageSize = new Size(96 * 3.370, 96 *2.125);
fixedDocument.DocumentPaginator.PageSize = new Size(96 * 8.5, 96 * 11);
for (int i = 0; i < 10; i++)
{
PageContent page = new PageContent();
FixedPage fixedPage = CreateOneFixedPage();
((IAddChild)page).AddChild(fixedPage);
fixedDocument.Pages.Add(page);
}
return fixedDocument;
}
private FixedPage CreateOneFixedPage()
{
FixedPage page = new FixedPage();
page.Background = Brushes.Red;
page.Width = 96 * 3.370;
page.Height = 96 * 2.125;
TextBlock tbTitle = new TextBlock();
tbTitle.Text = "xxx xxxxx Public School";
tbTitle.FontSize = 24;
tbTitle.Foreground = new SolidColorBrush(Colors.White);
tbTitle.FontFamily = new FontFamily("Arial");
FixedPage.SetLeft(tbTitle, 96 * 0.4); // left margin
FixedPage.SetTop(tbTitle, 96 * 0.04); // top margin
page.Children.Add((UIElement)tbTitle);
Image image = new Image
{
Source = new BitmapImage(new Uri("http://www.ready-range.co.uk/_assets/images/products/BHSRR40R0R.jpg")),
Height = 30,
Width = 30
};
Border b = new Border();
b.BorderThickness = new Thickness(1);
b.BorderBrush = Brushes.Yellow;
b.Child = image;
FixedPage.SetLeft(b, 96 * 0.3);
FixedPage.SetTop(b, 96 * 0.6); // top margin
page.Children.Add((UIElement)b);
//measure size of the layout
Size sz = new Size(96 * 3.370, 96 * 2.125);
page.Measure(sz);
page.Arrange(new Rect(new Point(), sz));
page.UpdateLayout();
return page;
}
这样可以成功打印,但是每页每张卡都这样打印:
问题是我想像上面的第一张图像一样打印,即每张纸自定义2 x 5。
非常感谢。
另一个stackoverflow问题的答案很有帮助。 为了获得期望的结果,我进行了一些更改,这是在WpfPrint
类中添加了自己的方法。
/// <summary>
/// Add fixed page to current fixed document
/// </summary>
/// <param name="card"></param>
/// <param name="flags"></param>
public void AddFixedPage(FixedPage card, ElementFlags flags)
{
card.Measure(_infiniteSize);
if (CurX > _fixedDocument.DocumentPaginator.PageSize.Width - MarginX)
{
CurY += card.DesiredSize.Height + MarginY;
CurX = MarginX;
}
double extraCheck = 0;
if ((flags & ElementFlags.BottomCheck2) == ElementFlags.BottomCheck2)
extraCheck = card.DesiredSize.Height;
if (CurY > _fixedDocument.DocumentPaginator.PageSize.Height - MarginY - extraCheck)
StartPage();
_curCanvas.Children.Add(card);
card.SetValue(Canvas.LeftProperty, CurX);
card.SetValue(Canvas.TopProperty, CurY);
CurX += card.DesiredSize.Width + MarginX; //Added margin x for proper display
if (((flags & ElementFlags.NewLine) == ElementFlags.NewLine) || CurX + card.DesiredSize.Width > _fixedDocument.DocumentPaginator.PageSize.Width)
{
CurX = MarginX;
CurY += card.DesiredSize.Height + MarginY;
}
}
现在,我们可以像这样简单地做到这一点:
WpfPrint printer = new WpfPrint(new Size(96 * 9, 96 * 11));
printer.CurrentElementMargin = new Thickness(4);
printer.CurrentFontFamily = new FontFamily("Arial");
printer.MarginX = 20;
printer.MarginY = 10;
现在我们可以遍历每个FixedPage:
for (int i = 0; i < 10; i++)
printer.AddFixedPage(CreateOneFixedPage(), WpfPrint.ElementFlags.BottomCheck2);
最后,发送打印命令,如下所示:
PrintDialog printDialog = new PrintDialog();
bool? pdResult = printDialog.ShowDialog();
if (pdResult != null && pdResult.Value)
printDialog.PrintDocument(printer.CurrentFixedDocument.DocumentPaginator, "Card Printing");
谢谢。
