我在RibbonControlsLibrary-http://schemas.microsoft.com/winfx/2006/xaml/presentation/ribbon中的每个对象中，ToolTipImage和ToolTipImageFooter的大小都有问题。
我有一个ResourceDictionary Pictures.xaml。我有从.svg转换成.Image的.xaml图片，定义为DrawingImages，如下所示：

Pictures.xaml ResourceDictionary中的图片我正在将对象放入DynamicResource之类的对象中。对于所有对象，尺寸都是正确的（如对象的（宽度和高度）模板中所定义）。
但是，当我定义ToolTipImage或ToolTipImageFooter时，此图片以900.165498 x 900.165498的奇怪尺寸显示。看起来这个大小是从ResourceDictionary中的Picture Path的定义加载的某个位置，但是我不知道在哪里以及为什么。 Xml / svg图片应该很灵活，不是吗？
<ribbon:RibbonButton Label="AAA" ToolTipDescription="Description Description" ToolTipTitle="Title" ToolTipImageSource="{DynamicResource B}" ToolTipFooterImageSource="{DynamicResource B}" />
有人已经解决了这个问题或一些想法？
谢谢！
