Hi there,
I believe that ComputeBandStats() should return 4 values min, max, mean and
stddev) [1] but the Python API is
returning just mean and stddev.
python:
>>> bd.ComputeBandStats()
(9.0071713001936118, 11.350094331448236)
>>> bd.ComputeRasterMinMax()
(-1.7899999618530273, 31.149999618530273)
gdalinfo:
Band 1 Block=360x1 Type=Float32, ColorInterp=Gray
Min=-1.790 Max=31.150
Minimum=-1.790, Maximum=31.150, Mean=9.007, StdDev=11.350
Unit Type: unspecified
Metadata:
STATISTICS_MINIMUM=-1.789999961853
STATISTICS_MAXIMUM=31.14999961853
STATISTICS_MEAN=9.0071713001936
STATISTICS_STDDEV=11.350094331448
Is that a bug?
See what happens in that case:
>>> bd1.SetStatistics(bd2.ComputeBandStats())
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "E:\Python25\Lib\site-packages\osgeo\gdal.py", line 729, in SetStatistics
return _gdal.Band_SetStatistics(*args)
TypeError: Band_SetStatistics() takes exactly 5 arguments (2 given)
My best regards,
Ivan
