是我还是MultiScaleImage甚至没有显式宽度和高度显示?出于某种原因,我无法填充网格单元格。它的行为与大多数其他元素不同。Silverlight MultiScaleImage不会填充可用空间
如果我在查看器上放弃高度和宽度,它根本不显示。
编辑:下面是完整的图片... XAML:
<UserControl x:Class="CliqueSite.DeepZoom.Viewer.ZoomPage"

</Grid.ColumnDefinitions>
<MultiScaleImage x:Name="Viewer" Margin="1,1,1,0" Height="675" Width="900" />

[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 PARAM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}");
}
