从 WPF 中的 Image 标记修改图像

发布于 2024-11-16 03:07:37 字数 1444 浏览 1 评论 0原文

我有一个显示一堆图像的表单。我希望能够通过另一个可执行文件（例如 Paint）修改此图像，并在退出时刷新图像（例如通过按钮）。

当我尝试将图像保存在油漆中时，它告诉我图像受到保护，这是由于表单以某种方式链接到图像。

有什么办法可以让这个工作吗？知道如何绕过这个问题吗？

谢谢。

编辑：这是我使用的结构（高度简化）

        <ListView Style="{StaticResource BaseListView}" x:Name="LstMoulures" Grid.Column="0" Background="#00000000" SelectionMode="Single" IsTextSearchEnabled="False" ScrollViewer.VerticalScrollBarVisibility="Auto">
           <ListView.ItemTemplate>
                <DataTemplate>
                    <Border BorderBrush="White" Margin="1,1,1,1" BorderThickness="2,2,2,2" CornerRadius="4">
                        <StackPanel Orientation="Horizontal" Margin="5,0,0,5" Height="200">
                            <Image x:Name="ImgPicture" Width="220" Height="195" Margin="2,5,2,2" GotFocus="ImgPicture_GotFocus" MouseLeftButtonDown="ImgPicture_MouseLeftButtonDown" MouseEnter="ImgPicture_MouseEnter" MouseLeave="ImgPicture_MouseLeave">
                                <Image.Source>
                                    <BitmapImage UriSource="{Binding DessinSource}" CacheOption="OnLoad" />
                                </Image.Source>
                            </Image>
                         </StackPanel>
                    </Border>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>

I have a form in which I display a bunch of image. I would like to be able to modify this image via another executable like paint and refresh the image when I quit (via a button for example).

When I try to save the image in paint,it tells me the image is protected, which is due to the form being somehow linked to the image.

is there any way to make this work ? Any idea how to bypass the problem ?

Thanks.

Edit : Here is the strucure (heaviliy simplified) I use

        <ListView Style="{StaticResource BaseListView}" x:Name="LstMoulures" Grid.Column="0" Background="#00000000" SelectionMode="Single" IsTextSearchEnabled="False" ScrollViewer.VerticalScrollBarVisibility="Auto">
           <ListView.ItemTemplate>
                <DataTemplate>
                    <Border BorderBrush="White" Margin="1,1,1,1" BorderThickness="2,2,2,2" CornerRadius="4">
                        <StackPanel Orientation="Horizontal" Margin="5,0,0,5" Height="200">
                            <Image x:Name="ImgPicture" Width="220" Height="195" Margin="2,5,2,2" GotFocus="ImgPicture_GotFocus" MouseLeftButtonDown="ImgPicture_MouseLeftButtonDown" MouseEnter="ImgPicture_MouseEnter" MouseLeave="ImgPicture_MouseLeave">
                                <Image.Source>
                                    <BitmapImage UriSource="{Binding DessinSource}" CacheOption="OnLoad" />
                                </Image.Source>
                            </Image>
                         </StackPanel>
                    </Border>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>

<Image>
    <Image.Source>
        <BitmapImage UriSource="test.jpg" CacheOption="OnLoad" />
    </Image.Source>
</Image>

您还可以读取该文件并将其重写为 MemoryStream 对象：

MemoryStream ms = new MemoryStream();
BitmapImage bi = new BitmapImage();

byte[] bytArray = File.ReadAllBytes(@"test.jpg");
ms.Write(bytArray, 0, bytArray.Length);
ms.Position = 0;
bi.BeginInit();
bi.StreamSource = ms;
bi.EndInit();
image.Source = bi;

要监视图像更改并刷新图像，您可以使用 FileSystemWatcher

<Image>
    <Image.Source>
        <BitmapImage UriSource="test.jpg" CacheOption="OnLoad" />
    </Image.Source>
</Image>

Also you can read the file and rewrite it to a MemoryStream object:

MemoryStream ms = new MemoryStream();
BitmapImage bi = new BitmapImage();

byte[] bytArray = File.ReadAllBytes(@"test.jpg");
ms.Write(bytArray, 0, bytArray.Length);
ms.Position = 0;
bi.BeginInit();
bi.StreamSource = ms;
bi.EndInit();
image.Source = bi;

For monitoring image changes and refreshing the image you can use FileSystemWatcher
