rawpy is an easy-to-use Python wrapper for the LibRaw library. It also contains some extra functionality for finding and repairing hot/dead pixels.
Sample code
Load a RAW file and save the postprocessed image using default parameters:
import rawpy
import imageio
path = 'image.nef'
raw = rawpy.imread(path)
rgb = raw.postprocess()
imageio.imsave('default.tiff', rgb)Save as 16-bit linear image:
rgb = raw.postprocess(gamma=(1,1), no_auto_bright=True, output_bps=16)
imageio.imsave('linear.tiff', rgb)Find bad pixels using multiple RAW files and repair them:
import rawpy.enhance
paths = ['image1.nef', 'image2.nef', 'image3.nef']
bad_pixels = rawpy.enhance.find_bad_pixels(paths)
for path in paths:
raw = rawpy.imread(path)
rawpy.enhance.repair_bad_pixels(raw, bad_pixels, method='median')
rgb = raw.postprocess()
imageio.imsave(path + '.tiff', rgb)Installation on Linux
You need to have the LibRaw library installed to use this wrapper.
On Ubuntu, you can get (an outdated) version with:
sudo apt-get install libraw-devOr install the latest developer version from the SVN repository:
git clone git://github.com/LibRaw/LibRaw.git libraw
git clone git://github.com/LibRaw/LibRaw-cmake.git libraw-cmake
cp -R libraw-cmake/* libraw ;
cd libraw
cmake .
sudo make installAfter that, it’s the usual pip install rawpy.
If you get the error “ImportError: libraw.so: cannot open shared object file: No such file or directory” when trying to use rawpy, then do the following:
echo "/usr/local/lib" | sudo tee /etc/ld.so.conf.d/99local.conf
sudo ldconfigThe LibRaw library is installed in /usr/local/lib and apparently this folder is not searched for libraries by default in some Linux distributions.
Installation on Windows and Mac OS X
Binaries are provided for Python 2.7, 3.3 and 3.4 for both 32 and 64 bit. These can be installed with a simple pip install --use-wheel rawpy (or just pip install rawpy if using pip >= 1.5).
Binaries for other Python versions are currently not produced but if there is a need then this is possible as well. In that case, just contact me.
