尝试找到有关幻灯片放映和效果的指南

问题描述

我正在寻找一个很好的解决方案，以便从编程环境中的图像创建幻灯片视频(因此，除非它是命令行或与.NET C#集成，否则我不能使用该组件)...到目前为止我还没有找到低于400美元的组件来完成Ken Burns(平移和缩放效果)，整合音乐并产生视频文件的功能.

所以！我发现除了平移和缩放效果之外，还有很多组件可以完成所有工作，我希望有人可以推荐一个更好的组件，或者为我提供线索或链接，或者链接到适当的文章，以充分解释我可以编写一些代码的效果进行图像处理(使我的起始jpg和其他jpg字符串具有相同的效果)

I''m looking for a good solution to create slideshow videos from images from within a programming environment (so I can''t use a component unless it is command line or integrates with .NET C#)... So far I have not found any components less than $400 that will do Ken Burns (Pan and Zoom effects), integrate music, and produce a video file.

So! I''ve found many components that do everything except the pan and zooming effect, and I am hoping someone could either recommend a better component OR give me a clue or link to a proper article explaining enough about the effect that I could write some code to do image manipulation (take my starting jpg and string additional jpgs to the same effect)

推荐答案

<Window x:Class="MoveAndZoom.Window1"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Title="Window1" Height="500" Width="500">
    <Canvas Grid.Row="1" Grid.Column="1" Grid.RowSpan="2" HorizontalAlignment="Stretch"

            VerticalAlignment="Stretch" x:Name="ImageHolder" >
        <Image Canvas.Left="0" MouseWheel="Img_MouseWheel" MouseMove="Img_MouseMove"

               MouseDown="Img_MouseDown" MouseUp="Img_MouseUp" Panel.ZIndex="0"

               Cursor="Hand" Canvas.Top="0" Height="150" Width="150" Source="sketch.jpg"

               x:Name="Img">
        </Image>
    </Canvas>
</Window>

和后面的代码是

and the Code Behind are

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;
namespace MoveAndZoom
{
    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        Point p;
        public Window1()
        {
            InitializeComponent();
        }
        private void Img_MouseWheel(object sender, MouseWheelEventArgs e)
        {
            Img.Height += e.Delta;
            Img.Width += e.Delta;
        }
        private void Img_MouseMove(object sender, MouseEventArgs e)
        {
            Point x = e.GetPosition(ImageHolder);
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                Canvas.SetLeft(Img, Canvas.GetLeft(Img) + (x.X - p.X));
                Canvas.SetTop(Img, Canvas.GetTop(Img) + (x.Y - p.Y));
            }
            p = x;
        }
        private void Img_MouseDown(object sender, MouseButtonEventArgs e)
        {
            Img.CaptureMouse();
            p = e.GetPosition(ImageHolder);
        }
        private void Img_MouseUp(object sender, MouseButtonEventArgs e)
        {
            Img.ReleaseMouseCapture();
        }
    }
}

您也可以对视频使用相同的代码

U can use the Same codes for Videos too
