使用矢量图像作为图像源。编程语言

Using Vector images as an image source. WPF , C#

我正在处理一个包含大量图像的项目。问题是,正如标题所说,我必须先将所有矢量图像转换为 png,然后才能将它们用作图像源。

我有在 illustrator 中创建的矢量图像。我在 .ai 项目文件中有它们,我该如何从这里开始?

我的目标是能够做到这一点:

<Image Width="70" Height="70" Source="MyVectorImage"/>

您可以使用 DrawingImage 作为图片来源。 DrawingImage 使用 Geometry(即矢量图形)而不是位图。

<Image>
    <Image.Source>
        <DrawingImage>
            <DrawingImage.Drawing>
                <GeometryDrawing>
                    <GeometryDrawing.Pen>
                        <Pen Thickness="2" Brush="Black"/>
                    </GeometryDrawing.Pen>
                    <GeometryDrawing.Geometry>
                        <RectangleGeometry Rect="100,100,100,100"/>
                    </GeometryDrawing.Geometry>
                </GeometryDrawing>
            </DrawingImage.Drawing>
        </DrawingImage>
    </Image.Source>
</Image>

您当然也可以将 Source 属性 绑定到 ImageSource 类型的视图模型 属性,其中包含您将从原始矢量数据创建的 DrawingImage。

如果你想从几何路径图像中获取ImageSource到你的cs文件中,你可以将drawingImage放入资源文件中:Icons.xaml

<DrawingImage x:Key="hazelnut">
    <DrawingImage.Drawing>
        <DrawingGroup>
            <GeometryDrawing Brush="Black">
                <GeometryDrawing.Geometry>
                    <GeometryGroup>
                        <PathGeometry Figures="M 16.6309,18.6563C 17.1309,8.15625 29.8809,14.1563 29.8809,14.1563C 30.8809,11.1563 34.1308,11.4063 34.1308,11.4063C 33.5,12 34.6309,13.1563 34.6309,13.1563C 32.1309,13.1562 31.1309,14.9062 31.1309,14.9062C 41.1309,23.9062 32.6309,27.9063 32.6309,27.9062C 24.6309,24.9063 21.1309,22.1562 16.6309,18.6563 Z M 16.6309,19.9063C 21.6309,24.1563 25.1309,26.1562 31.6309,28.6562C 31.6309,28.6562 26.3809,39.1562 18.3809,36.1563C 18.3809,36.1563 18,38 16.3809,36.9063C 15,36 16.3809,34.9063 16.3809,34.9063C 16.3809,34.9063 10.1309,30.9062 16.6309,19.9063 Z ">
                            <PathGeometry.Transform>
                                <TransformGroup>
                                    <ScaleTransform
                                        CenterX="23"
                                        CenterY="20"
                                        ScaleX="0.45"
                                        ScaleY="0.45" />
                                </TransformGroup>
                            </PathGeometry.Transform>
                        </PathGeometry>
                    </GeometryGroup>
                </GeometryDrawing.Geometry>
            </GeometryDrawing>
        </DrawingGroup>
    </DrawingImage.Drawing>
</DrawingImage>

加上你App.xaml:

<Application.Resources>
    <ResourceDictionary>

        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/Resources/Icons.xaml"/>
        </ResourceDictionary.MergedDictionaries>

    </ResourceDictionary>
</Application.Resources>

并在您的 cs 文件中使用它,例如:

    ImageSource image = ResourcePathToImageSource("hazelnut");


    private ImageSource ResourcePathToImageSource(string resourcesName)
    {
        return (DrawingImage)Application.Current.TryFindResource(resourcesName);
    }
