[英]How to display a window half of its original size
我正在A4中打印WPF窗口,因此最初的窗口大小很大。 我想將其顯示為原始尺寸的一半,而不修改打印輸出。 有任何想法嗎?
這是我打印的方法
private void printItemList(string printerName)
{
//printButton.Visibility = Visibility.Collapsed;
//cancelButton.Visibility = Visibility.Collapsed;
PrintDialog printDlg = new System.Windows.Controls.PrintDialog();
printDlg.PrintQueue = new System.Printing.PrintQueue(new System.Printing.PrintServer(), printerName);
System.Printing.PrintCapabilities capabilities = printDlg.PrintQueue.GetPrintCapabilities(printDlg.PrintTicket);
//get scale of the print wrt to screen of WPF visual
double scale = Math.Min(capabilities.PageImageableArea.ExtentWidth / this.ActualWidth, capabilities.PageImageableArea.ExtentHeight /
this.ActualHeight);
//Transform the Visual to scale
this.LayoutTransform = new ScaleTransform(scale, scale);
//get the size of the printer page
Size sz = new Size(this.ActualWidth, this.ActualHeight); //(8.5 * 96.0, 11.0 * 96.0);
//update the layout of the visual to the printer page size.
this.Measure(sz);
this.Arrange(new Rect(new Point(capabilities.PageImageableArea.OriginWidth, capabilities.PageImageableArea.OriginHeight), sz));
//now print the visual to printer to fit on the one page.
printDlg.PrintVisual(this, "Print Page");
this.DialogResult = true;
}
ViewBox可以實現我的想法,我只需要確保在執行打印之前調整其大小即可。 謝謝你的提示。
