Manually setting white balance ratio.

[Septembit]

Hello, do anyone know in pypylon there is way of setting white balance manually. Just like C++ does in this link https://docs.baslerweb.com/balance-white.

// Set the red intensity to 108.789%
camera.BalanceRatioSelector.SetValue(BalanceRatioSelector_Red);
camera.BalanceRatio.SetValue(1.08789);
// Set the green intensity to 100%
camera.BalanceRatioSelector.SetValue(BalanceRatioSelector_Green);
camera.BalanceRatio.SetValue(1.0);
// Set the blue intensity to 219.678%
camera.BalanceRatioSelector.SetValue(BalanceRatioSelector_Blue);
camera.BalanceRatio.SetValue(2.19678);

Hi @Septembit,

the c++ API and the pypylon API are very close to each other.
See pypylon-samples for in depth background and documentation.

Typically a search'n'replace is enough ;-)

You can use this sed script to convert the C++ Basler product documentation code snippets to python

cat <sample_code.cpp> | sed -E 's/(\S+)\.(\S+).SetValue\(\s*\2_(\S+)\)/\1.\2\.SetValue("\3")/;s/^\/\//#/;s/SetValue\((.*)\)/Value = \1/;s/;\s*$//'

so your request gets:

# Set the red intensity to 108.789%
camera.BalanceRatioSelector.Value = "Red"
camera.BalanceRatio.Value = 1.08789
# Set the green intensity to 100%
camera.BalanceRatioSelector.Value = "Green"
camera.BalanceRatio.Value = 1.0
# Set the blue intensity to 219.678%
camera.BalanceRatioSelector.Value = "Blue"
camera.BalanceRatio.Value = 2.19678

If you don't have sed on your system you can use an online tool like https://sed.js.org/ with -E 's/(\S+)\.(\S+).SetValue\(\s*\2_(\S+)\)/\1.\2\.SetValue("\3")/;s/^\/\//#/;s/SetValue\((.*)\)/Value = \1/;s/;\s*$//' as Command line

Thank you!

How can I change it in python ?

You can look up every camera feature in our products documentation docs.baslerweb.com
We have python sample code for every feature online.
