你好，

在RichTextBox内的FlowDocument中，这两个属性是无效的，如果你使用FlowDocumentReader, 它们将会正常工作：

<FlowDocumentReader>
            <FlowDocument >
                <Paragraph>
                    <Figure Background="Aqua"
                            Name="myFigure"
                            Width="140" Height="50" 
                            HorizontalAnchor="PageCenter"
                            VerticalAnchor="PageCenter"
                            HorizontalOffset="100" 
                            VerticalOffset="20" 
                            WrapDirection="Both">
                        <Paragraph>
                            sssssssssssssss
                        </Paragraph>
                    </Figure>
                </Paragraph>
            </FlowDocument>
</FlowDocumentReader>

回答者建议使用 FixedDocument 或者 Annotations， 你可以尝试下

你好. 我知道这个在 FlowDocumentReader 是起作用的. 但是我想要编辑文本和图片, 像Word那样. 所以我要使用 RichTextBox 所以我想知道如何在RichTextBox 里让这两个属性能正常工作, 或者是有什么别的可编辑的控件承载FlowDocument

你好，

据我所知，是没有可以使得Figure的这两个属性可以工作的其他办法，如果你需要在RichTextBox中实现类似功能，可以使用Floater，利用其 Margin 属性调整位置:

<RichTextBox>
            <FlowDocument >
                <Paragraph>
                    <Floater Background="Red" Width="140" HorizontalAlignment="Left" Margin="150,50,Auto,Auto">
                        <Paragraph>
                            sssssssssssssss
                        </Paragraph>
                    </Floater>
                </Paragraph>
            </FlowDocument>
</RichTextBox>
