如果没有明确的宽度和高度,是我还是MultiScaleImage甚至不显示?由于某种原因,我不能让它填充网格单元格。它的行为与大多数其他元素不同。
如果我在Viewer上丢弃高度和宽度,它根本不会显示。
编辑:这是完整的图片...... XAML:
<UserControl x:Class="CliqueSite.DeepZoom.Viewer.ZoomPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid x:Name="LayoutRoot" Background="Black">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="34" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<MultiScaleImage x:Name="Viewer" Margin="1,1,1,0" Height="675" Width="900" />
<Rectangle Grid.Row="1">
<Rectangle.Fill>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FF000000"/>
<GradientStop Color="#FF808080" Offset="1"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<Button HorizontalAlignment="Right" Margin="0,0,4,4" VerticalAlignment="Bottom" Padding="6" Grid.Row="1"
Content="Zoom Reset" x:Name="ZoomReset" FontSize="9" FontFamily="Verdana" />
</Grid>
背后的相关代码:
[ScriptableMember]
public void SetSource(int width, int height, int tileSize, int id, string urlToFormat)
{
Viewer.Source = new ViewerSource(width, height, tileSize, id, urlToFormat);
double x = 0;
double y = 0;
double w = 1;
if ((width > height && Viewer.Width > Viewer.Height) || (width > height && Viewer.Width < Viewer.Height))
{
double scaleFactor = Viewer.Width / width;
double adjustedHeight = height * scaleFactor;
double topSpace = (Viewer.Height - adjustedHeight) / 2;
y = -(topSpace / Viewer.Height) * (Viewer.Height / Viewer.Width);
}
else
{
double scaleFactor = Viewer.Height / height;
double adjustedWidth = width * scaleFactor;
w = Viewer.Width / adjustedWidth;
double leftSpace = (Viewer.Width - adjustedWidth) / 2;
x = -(leftSpace / Viewer.Width) * w;
}
_viewportOrigin = new Point(x, y);
_viewportWidth = w;
ResetZoom();
}
Javascript代码(从嵌入对象的onload参数运行):
function LoadImage() {
var viewer = $("#DeepZoomViewer")[0];
viewer.content.Bridge.SetSource(<%= Model.ZoomProperties.Width %>, <%= Model.ZoomProperties.Height %>, 256, <%= Model.Photo.ID %>, "http://localhost:7070/TileHandler.ashx?id={0}&level={1}&x={2}&y={3}");
}

当我将h / w设置为Auto时,它为我填充第0行就好了,就像这样:
<MultiScaleImage x:Name="Viewer" Margin="1,1,1,0" Height="Auto" Width="Auto" />
你甚至可以在行中进行额外的测量,但是当我这样做时不需要它:
<MultiScaleImage Grid.Row="0" x:Name="Viewer" Margin="1,1,1,0" Height="Auto" Width="Auto" />

尝试更改网格单元格定义,如下所示: -
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="34" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=*" />
</Grid.ColumnDefinitions>
MultiscaleImage控件指定图像的“自然”大小(这将是巨大的)是没有意义的。因此,它希望给定尺寸或拉伸到可用尺寸。您需要在gird行/列定义中使用*以确保将Grid所在的控件的剩余可用大小传递到放置MultiscaleImage控件的单元位置。
