Hello guys,
I'm struggling to load images from XAML using the XamlReader with
IronPython. The equivalent with compiled XAML and C# works fine -
however this doesn't directly use the XamlReader so I wonder if it is an
issue with that?
The Python code is:
import clr
clr.AddReference("PresentationFramework")
clr.AddReference("PresentationCore")
from System.IO import File
from System.Windows.Markup import XamlReader
from System.Windows import (
Application, Window
)
class HelloWorld(Window):
def __init__(self):
stream = File.OpenRead("HelloWorld.xaml")
self.Content = XamlReader.Load(stream)
hello = HelloWorld()
app = Application()
app.Run(hello)
The XAML is:
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation";
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml";>
<Grid>
<Image Source="images/image.jpg" Stretch="None"
HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Window>
The image stubbornly refuses to appear and reports an ActualHeight and
ActualWidth of 0.0 if I inspect it.
I've even tried instantiating a BitmapImage directly from code and
setting it as the Source on the image:
image = root.FindName("image")
bi = BitmapImage()
bi.BeginInit()
bi.UriSource = Uri("/images/image.jpg", UriKind.RelativeOrAbsolute);
bi.EndInit()
image.Source = bi
Same problem - the image doesn't show. Anyone got any clues?
