去年10月份, 我曾写过一篇"给WPF示例图形加上方便查看大小的格子"的BLOG（http://blog.csdn.net/johnsuna/archive/2007/10/19/1832994.aspx）,这次由于需要,将它完善一下,可以有效地区别100的整数倍逻辑像素（与设备无关像素）单位的显示。

显示效果：

XAML代码：
<Canvas Width="752.009766" Height="1192.558594" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                            </GeometryDrawing>
                        </DrawingGroup.Children>
                    </DrawingGroup>
                </DrawingBrush.Drawing>
            </DrawingBrush>

            <!-- 这里是外框线 -->
            <Style x:Key="MyGridBorderStyle">
                <Setter Property="Border.Background" Value="{StaticResource MyGridBrushResource}"/>
                <Setter Property="Border.HorizontalAlignment" Value="Center"/>
                <Setter Property="Border.VerticalAlignment" Value="Top"/>
                <Setter Property="Border.BorderBrush" Value="Black"/>
                <Setter Property="Border.BorderThickness" Value="1"/>
            </Style>
        </Canvas.Resources>

        <!-- 引用方式 -->
        <Border Style="{StaticResource MyGridBorderStyle}">
            <Canvas Width="630" Height="348">
                <Path StrokeThickness="5" Stroke="Orange" StrokeMiterLimit="1"

/>
            </Canvas>
        </Border>

</Canvas>

而在此之前初始版本的演示效果为：

很明显，当前已完善版本看起来更清晰明了。
