当图像为2000x1500 png时,我的MultiScaleImage返回的宽高比为1。更奇怪的是,xml元数据在宽高比标签中显示1.33,但其高度和宽度为1.
我在这里错过了什么?
感谢您的帮助!
的元数据:
<Metadata version="1">
<AspectRatio>1.33333333333333</AspectRatio>
<Image>
<FileName>C:\Documents and Settings\asmith\Desktop\Temp\DZComposer\Testing1\Source Images\2000x1500 sample image.png</FileName>
<x>0</x>
<y>0</y>
<Width>1</Width>
<Height>1</Height>
<ZOrder>1</ZOrder>
<Tag />
</Image>
</Metadata>
dzc_output.xml同意这一点:
<Collection MaxLevel="8" TileSize="256" Format="jpg" NextItemId="1" ServerFormat="Default" xmlns="http://schemas.microsoft.com/deepzoom/2009">
<Items>
<I Id="0" N="0" Source="dzc_output_images/2000x1500%20sample%20image.xml">
<Size Width="2000" Height="1500" />
<Viewport Width="1" X="-0" Y="-0" />
</I>
</Items>
</Collection>
MSI声明:
<MultiScaleImage
x:Name="msi" Grid.Column="1" Grid.Row="1" Width="720" Height="540"
MouseMove="msi_MouseMove"
MouseLeftButtonUp="msi_MouseLeftButtonUp">
</MultiScaleImage>
财产输出: (基于msi的mousemove)
宽度:720
身高:540
AspectRatio: 1
宽度/宽高比:720
逻辑X:0.55555555556
逻辑Y:0.37361111111
逻辑X *宽度:400
逻辑Y *宽度:269
原始X:400
原始Y:269
视口来源:0,0
视口宽度:1
填充属性输出的Codebehind:
private void msi_MouseMove(object sender, MouseEventArgs e)
{
txtWidth.Text = msi.Width.ToString();
txtHeight.Text = msi.Height.ToString();
txtAspectRatio.Text = msi.AspectRatio.ToString();
txtWidthDivAR.Text = (msi.Width / msi.AspectRatio).ToString();
Point pLogical = msi.ElementToLogicalPoint(e.GetPosition(msi));
txtMsiX.Text = pLogical.X.ToString();
txtMsiY.Text = pLogical.Y.ToString();
txtLogicYxW.Text = (pLogical.Y * msi.Width).ToString();
txtLogicXxW.Text = (pLogical.X * msi.Width).ToString();
Point pRaw = e.GetPosition(msi);
txtRawX.Text = pRaw.X.ToString();
txtRawY.Text = pRaw.Y.ToString();
txtVPO.Text = msi.ViewportOrigin.ToString();
txtVPW.Text = msi.ViewportWidth.ToString();
}
答案 0 :(得分:0)
dzc_output.xml的宽度和高度是原始图像大小(以像素为单位),而元数据中的宽高比是MultiScaleImage的宽度和高度整体。元数据中图像的宽度和高度符合多尺度图像的大小。
