[Python.NET] How to use BitmapSource from System.Windows.Media.Imaging ?

[Daniel Krause]

Hi Jojo,

thanks for your help.

The following code is running (64bit-Windows):

import clr
import sys
sys.path.append("C:\\Windows\\Microsoft.NET\\Framework64\\v4.0.30319\\WPF")
clr.AddReference("PresentationCore")
from System.Windows.Media.Imaging import BitmapSource
bitmapsrc = BitmapSource
print bitmapsrc

Console output:
<class 'System.Windows.Media.Imaging.BitmapSource'>

Best regards
Daniel
