SOLVED How to change the EXR compression method via python

I need to change my exr compression to one scanline at a time but beside using a c4d default document is there any other way to change it directly in a script?

Here you go: https://github.com/PluginCafe/cinema4d_py_sdk_extended/blob/762c9d505e0ed2f09dafdd8c6cef972a82d084e8/scripts/04_3d_concepts/rendering/render_settings_openexr_data_r20.py

The script change the compression method to zip not to Zips or what i expected: RLE because rle was the given value.

Oh yes, you are right. The SDK example doesn't work at all.
Problem is, maxon.Id is wrong. maxon.InternedId would be the correct way for setting the save options. Here's the correct code:

"""
Copyright: MAXON Computer GmbH

Description:
    - Configures OpenEXR output render format with SetImageSettingsDictionary() then reads these with GetImageSettingsDictionary().
Class/method highlighted:
    - c4d.bitmaps.SetImageSettingsDictionary()
    - c4d.bitmaps.GetImageSettingsDictionary()
Compatible:

    - R20, R21, S22, R23
"""
import c4d
import maxon


def main():
    # Retrieves render data and its container
    renderData = doc.GetActiveRenderData()
    bc = renderData.GetDataInstance()

    # Gets image filters options
    saveOptions = bc.GetContainerInstance(c4d.RDATA_SAVEOPTIONS)

    # Sets OpenEXR output format
    bc[c4d.RDATA_FORMAT] = c4d.FILTER_EXR

    # Defines OpenEXR settings
    compressionmethodID = maxon.InternedId('net.maxon.mediasession.openexr.export.compressionmethod')
    halffloatID = maxon.InternedId('net.maxon.mediasession.openexr.export.halffloat')
    layernumberingID = maxon.InternedId('net.maxon.mediasession.openexr.export.layernumbering')

    # Configures OpenEXR format options with a maxon.DataDictionary
    exportSettings = maxon.DataDictionary()
    exportSettings.Set(compressionmethodID, maxon.Id("rle"))
    exportSettings.Set(halffloatID, True)
    exportSettings.Set(layernumberingID, True)

    # Stores settings in render data container
    c4d.bitmaps.SetImageSettingsDictionary(exportSettings, saveOptions, c4d.FILTER_EXR)

    # Pushes an update event to Cinema 4D
    c4d.EventAdd()

    # Retrieves OpenEXR images settings
    settings = c4d.bitmaps.GetImageSettingsDictionary(saveOptions, c4d.FILTER_EXR)

    # Reads and prints OpenEXR format options
    print("openexr.export.compressionmethod: " + str(settings.Get(compressionmethodID)))
    print("openexr.export.halffloat: " + str(settings.Get(halffloatID)))
    print("openexr.export.layernumbering: " + str(settings.Get(layernumberingID)))


if __name__ == '__main__':
    main()

@m_adam maybe the code example in the repo should be updated.

Thanks a lot for the update and yes maxon.InternedId should be used instead of maxon.Id.
I will take care of updating the example in Github.
Cheers,
Maxime.
