WPF(Windows Presentation Foundation)是微软推出的基于Windows 的用户界面框架,属于.NET Framework 3.0的一部分。它提供了统一的编程模型、语言和框架,真正做到了分离界面设计人员与开发人员的工作;同时它提供了全新的多媒体交互用户图形界面。
还是话不多说,直接上码:
1.新建WpfApp应用程序
2.MainWindow.xaml文件代码如下:
3.MainWindow.xaml.cs文件代码如下:
using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using System.Drawing; using System.Drawing.Drawing2D; namespace WpfApp1 { ////// Interaction logic for MainWindow.xaml /// public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } public void Button_Click(object sender, RoutedEventArgs e) WriteableBitmap wb = new WriteableBitmap((int)imgGrid.ActualWidth, (int)imgGrid.ActualHeight, 96, 96, PixelFormats.Pbgra32, null); wb.Lock(); Bitmap backBitmap = new Bitmap((int)imgGrid.ActualWidth, (int)imgGrid.ActualHeight, wb.BackBufferStride, System.Drawing.Imaging.PixelFormat.Format32bppArgb, wb.BackBuffer); Int32Rect rect = new Int32Rect(0, 0, (int)imgGrid.ActualWidth, (int)imgGrid.ActualHeight); byte[] pixels = new byte[(int)imgGrid.ActualWidth * (int)imgGrid.ActualHeight * wb.Format.BitsPerPixel / 8]; Random rand = new Random(); for (int y = 0; y
效果如下:
