[英]Using Vector images as an image source. WPF , C#
我正在處理一個包含大量圖像的項目。 問題是,正如標題所說,我必須將所有矢量圖像轉換為 png,然后才能將它們用作圖像源。
我有在 illustrator 中創建的矢量圖像。 我在 .ai 項目文件中有它們,我如何從這里開始?
我的目標是能夠做到這一點:
<Image Width="70" Height="70" Source="MyVectorImage"/>
如果要從幾何路徑圖像獲取ImageSource
到您的 cs 文件中,您可以將drawingImage
放入資源文件: 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>
並添加你App.xaml
:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/Resources/Icons.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
並在您的 cs 文件中使用它,例如:
ImageSource image = ResourcePathToImageSource("hazelnut");
private ImageSource ResourcePathToImageSource(string resourcesName)
{
return (DrawingImage)Application.Current.TryFindResource(resourcesName);
}
您可以使用DrawingImage
作為圖像的源。 DrawingImage 使用幾何圖形(即矢量圖形)而不是位圖。
<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>
您當然也可以將 Source 屬性綁定到 ImageSource 類型的視圖模型屬性,該屬性包含您將從原始矢量數據創建的 DrawingImage。
