CameraFinder & Python doc

[maximecharriere]

1st question In C# there is a CameraFinder to enumarate all connected cameras and emulators. Is there an equivalence in Python ?

---

2nd question As explained in some places, I can use the C++ doc for the Python wrapper. But I don't understand because many C++ examples don't work.

For example for camera emulation with custom images :

C++ doc

// ** Custom Test Images **
// Disable standard test images
camera.TestImageSelector.SetValue(TestImageSelector_Off);
// Enable custom test images
camera.ImageFileMode.SetValue(ImageFileMode_On);
// Load custom test image from disk
camera.ImageFilename.SetValue("c:\\images\\image1.png");

What I coded in Python based on the C++ doc and did not work

# ** Custom Test Images **
# Disable standard test images
camera.TestImageSelector.SetValue(pylon.TestImageSelector_Off)
# Enable custom test images
camera.ImageFileMode.SetValue(pylon.ImageFileMode_On)
# Load custom test image from disk
camera.ImageFilename.SetValue("c:\\images\\image1.png")

What I had to code in Python to make it work

# ** Custom Test Images **
# Disable standard test images
camera.TestImageSelector = "Off"
# Enable custom test images
camera.ImageFileMode = "On"
# Load custom test image from disk
camera.ImageFilename = "c:\\images\\image1.png"

Where can I find what to write to call methods and get/set values ? How do I know what methods and enums are available in python and how to write them ?

1) Try following code Please refer to following code https://github.com/basler/pypylon/blob/master/samples/grabmultiplecameras.py

2) Some parameter is not available on across the camera models. So you need to check with pylonviewer if the parameter available on your camera.

or via SDK e.g if genicam.IsAvailable(camera.Exposuretime):
