Hi, CreatorOptions has a string field "ecLevel" so I supposed I should use "L", "M", "Q", "H" but as it turns out one has to use "0" to "8". |

AFAIK, zint is used. The zint parameter "error correction level" may be applicable to multiple symbologies (PDF417,Aztec,QR).

CreatorOptionsmachinery useszintiff you configurezxing-cppwithZXING_WRITERS=NEW(orBOTH). I suspect you did not do that, because if you would, then passing any of "L", "M", "Q", "H" for the QRCode symbologies would actually work. Alternatively, you could pass plain numbers 1-4 as well as a percentage like "50%".If that does not work, then the old
MultiFormatWriteris used in the background (ZXING_WRITERS=ON) and there, the mapping is different for historical reasons: 0-8 are mapped like this 0/1 -> L, 2/3 -> M, etc. (IIRC). I actually don't intend to properly release the old writers as a backend for the new API.
