  1. PODeep Zoom Aspect Ratio Returning Wrong Value

    copied!<p>My MultiScaleImage is returning an aspect ratio of 1, when the image is a 2000x1500 png. What's even more odd, is that the xml metadata shows 1.33 in the aspect ratio tag, but then has a height and width of 1. </p> <p>What the heck am I missing here? </p> <p>Thanks for any help!</p> <p><strong>MetaData:</strong></p> <pre><code>&lt;Metadata version="1"&gt; &lt;AspectRatio&gt;1.33333333333333&lt;/AspectRatio&gt; &lt;Image&gt; &lt;FileName&gt;C:\Documents and Settings\asmith\Desktop\Temp\DZComposer\Testing1\Source Images\2000x1500 sample image.png&lt;/FileName&gt; &lt;x&gt;0&lt;/x&gt; &lt;y&gt;0&lt;/y&gt; &lt;Width&gt;1&lt;/Width&gt; &lt;Height&gt;1&lt;/Height&gt; &lt;ZOrder&gt;1&lt;/ZOrder&gt; &lt;Tag /&gt; &lt;/Image&gt; &lt;/Metadata&gt; </code></pre> <p><strong>The dzc_output.xml agrees with this also:</strong></p> <pre><code>&lt;Collection MaxLevel="8" TileSize="256" Format="jpg" NextItemId="1" ServerFormat="Default" xmlns="http://schemas.microsoft.com/deepzoom/2009"&gt; &lt;Items&gt; &lt;I Id="0" N="0" Source="dzc_output_images/2000x1500%20sample%20image.xml"&gt; &lt;Size Width="2000" Height="1500" /&gt; &lt;Viewport Width="1" X="-0" Y="-0" /&gt; &lt;/I&gt; &lt;/Items&gt; &lt;/Collection&gt; </code></pre> <p><strong>MSI Declaration:</strong></p> <pre><code>&lt;MultiScaleImage x:Name="msi" Grid.Column="1" Grid.Row="1" Width="720" Height="540" MouseMove="msi_MouseMove" MouseLeftButtonUp="msi_MouseLeftButtonUp"&gt; &lt;/MultiScaleImage&gt; </code></pre> <p><strong>Property outputs:</strong> <em>(based on the msi's mousemove)</em></p> <p>Width: 720</p> <p>Height: 540</p> <p>AspectRatio: <strong>1</strong></p> <p>Width / Aspect Ratio: 720</p> <p>Logical X: 0.55555555556</p> <p>Logical Y: 0.37361111111</p> <p>Logical X * Width: 400</p> <p>Logical Y * Width: 269</p> <p>Raw X: 400</p> <p>Raw Y: 269</p> <p>Viewport Origin: 0,0</p> <p>Viewport Width: 1</p> <p><strong>Codebehind that populates property outputs:</strong></p> <pre><code>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(); } </code></pre>
