已在做什么:
我想在我的应用程序中使用SVG图标。 因此,我从Material.io下载了一些图标,并使用Inkscape将它们转换为XAML文件。
这些文件的内容然后在<VisualBrush>
中用作<Rectangle.OpacityMask>
。
这样,我可以根据需要更改前景色和后景色。
那很重要,因为我希望能够更改图标颜色,而不必重新设计。
VisualBrushes和颜色位于实际应用程序的资源字典中,但是为了更好地解释,我将所有内容都复制到一个窗口中。
示例代码:
<Grid Background="Green" Margin="4">
<Rectangle Fill="Blue" Width="24" Height="24" >
<Rectangle.OpacityMask>
<VisualBrush Stretch="Uniform">
<VisualBrush.Visual>
<!-- from SVG (baseline-chevron_right-24px)-->
<Viewbox xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" Stretch="Uniform">
<Canvas Width="24" Height="24">
<Canvas.RenderTransform>
<TranslateTransform X="0" Y="0"/>
</Canvas.RenderTransform>
<Canvas.Resources/>
<!--Unknown tag: metadata-->
<!--Unknown tag: sodipodi:namedview-->
<Path xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Fill="#000000" Width="24" Height="24">
<Path.Data>
<PathGeometry Figures="M10 6L8.59 7.41 13.17 12l-4.58 4.59L10 18l6-6z" FillRule="NonZero"/>
</Path.Data>
</Path>
<Path xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<Path.Data >
<PathGeometry Figures="M0 0h24v24H0z" FillRule="NonZero" />
</Path.Data>
</Path>
</Canvas>
</Viewbox>
<!-- end from SVG-->
</VisualBrush.Visual>
</VisualBrush>
</Rectangle.OpacityMask>
</Rectangle>
</Grid>
Wat不起作用:
图标按我想要的方式缩放。
如果我使用<VisualBrush Stretch="None">
,则图标的大小都相同,但是当我将矩形变大时,它们的大小不会增加。那正是我对Stretch =“ None”的期望,但不是我所需要的。
如果我使用<VisualBrush Stretch="Uniform">
,则图标会按比例放大到矩形大小,但它们会变得太大,并且大小会有所不同。 (“人字形”比“导出”图标大得多)。
我认为VisualBrush忽略了Canvas和Path的大小,而是使用路径的 visible 部分的大小。
诸如Fill的其他拉伸变体也无法正常工作:
我需要什么
图标应该像常规图标那样以矩形大小增长和缩小。但是它们应该以相同的比例增长/缩小。
问题:
有没有可能使我获得理想行为的设置?
奖金:
我想在不修改ViewBox或其内容的情况下实现所需的功能,因为那是从Inkscape自动生成的代码。
