when run debayer dng -o exr,output error message'Error: could not locate oiiotool'.How do I install oiiotool dependency?
I am confused about the color transform matrix.
In debayer file line179:
mtx_XYZ_to_ACEScg = '1.65885437,-0.31185693,-0.24315603,-0.66228336,1.61220002,0.01585913,0.01148057,-0.00923633,0.91668653'
This has slight differences with the aces offical transform matrix:
R_out = 1.6410233797 * R_in + -0.3248032942 * G_in + -0.2364246952 * B_in;
G_out = -0.6636628587 * R_in + 1.6153315917 * G_in + 0.0167563477 * B_in;
B_out = 0.0117218943 * R_in + -0.0082844420 * G_in + 0.9883948585 * B_in;
In comments, it says "D65-aligned XYZ to ACEScg with CAT02 CAT. Works with dcraw"
What is the meaning of D65-aligned XYZ? Is the XYZ output of dcraw not standard?
I am trying to read raw image into ACES Ap0 color space. I find in libraw color matrix, there is a comment:
Coffin's values (commented out) are not adapted from ACES "D60-like" WP to D65
I did some tests with the libraw color matrix:
So, is the result of libraw xyz standard? At least I found the LibRaw_constants::xyz_rgb matrix is standard matrix for sRGB->XYZ.
Thanks for your reply!

请问使用debayer需要安装什么,比如设置DEBAYER_ENGINE = 'dc',需要安装哪些?如何安装?
libraw安装编译之后并没有起作用,oiio安装不了
Ok so first a few "fixes"for the readme.md
on MacOS BigSur I have to install pip using get-pip.py it does not work via homebrew:
brew install openimageio dcraw python exiftool
curl -O https://bootstrap.pypa.io/pip/2.7/get-pip.py
python get-pip.py
pip install PyYAML
so far so good if I launch ./debayer
I get the help printout, but when I run ./debayer input_paths /Volumes/raid/HDri/testJEDY
I end up with this:
Traceback (most recent call last):
File "./debayer", line 709, in <module>
debayer = Debayer()
File "./debayer", line 61, in __init__
self.success = self.validate()
File "./debayer", line 374, in validate
if not os.path.exists(self.ocioconfig):
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/genericpath.py", line 26, in exists
os.stat(path)
TypeError: coercing to Unicode: need string or buffer, NoneType found
Any Idea?
Hi,
I really want to try this tool. I finally figured out how to get everything installed on my Mac using brew and pip. I get Debayer command not found when I try to run it in terminal. Not sure where to go from here. Any help is appreciated.
