Hi,

I am trying to add the ZoomPanel to my image editing application. It works so far but I can not seem to figure out how to zoom out past the ZoomPanel boundaries.

Here is an image of my Minimum Zoom, I can not zoom out further than that.

   


And here is my code:

Code:

<UserControl x:Class="Electric.View.CanvasView"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
            xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
            xmlns:ab2d="clr-namespace:Ab2d.Controls;assembly=Ab2d.Controls.ZoomPanel"
            xmlns:local="clr-namespace:Electric.View"
            DataContext="{Binding Source={StaticResource Locator}, Path=Canvas}"
            mc:Ignorable="d"
            d:DesignHeight="800" d:DesignWidth="800"
            Background="Green">
   <Grid>
       <ab2d:ZoomPanel Name="ZoomPanel1" ZoomMode="Rectangle" VerticalAlignment="Center" HorizontalAlignment="Center"
           ViewboxLimits="0 0 1 1"
            ViewboxMinSize="0.1 0.1"
            IsViewboxLimited="False"
            IsZoomPositionPreserved="True"
            Viewbox="0 0 1 1">
            <Image
                Source="{Binding ViewerImage}"
                Width="{Binding ViewerImage.Width}"
                Height="{Binding ViewerImage.Height}"/>
        </ab2d:ZoomPanel>
       <ab2d:ZoomController VerticalAlignment="Top" HorizontalAlignment="Right"/>
       <ab2d:ZoomPanelNavigator VerticalAlignment="Top" HorizontalAlignment="Left"/>
       <ab2d:ZoomPanelMiniMap VerticalAlignment="Bottom" HorizontalAlignment="Right"/>
   </Grid>
</UserControl>

Can you help?

When you use ZoomPanelNavigator it by default limits the zoom factor to the limits defined by the ZoomPanelNavigator.MinZoomFactor and ZoomPanelNavigator.MaxZoomFactor properties. But you can disable this by setting the ZoomPanelNavigator.IsZoomPanelLimitedToMinMaxZoomFactors to false. You can also change the limits so they will suit your needs.

See ZoomPanelNavigator sample that comes with ZoomPanel samples project for more info.
