Peter Kronenberg commented on TIKA-3260:
----------------------------------------
More info for the documentation
Maybe this will help somebody. I just spent the last day trying to resolve all
the dependencies needed for a Linux Docker image. Here's what I came up with
{code:java}
FROM openjdk:8-jre-alpine
RUN apk add --no-cache tesseract-ocr python3 py3-numpy imagemagick
python3-tkinter && \
pip3 --no-cache-dir install --upgrade pip setuptools wheel && \
apk add --no-cache --virtual .build-deps gcc g++ zlib-dev make python3-dev
py-numpy-dev jpeg-dev gfortran lapack-dev && \
pip3 --no-cache-dir install scikit-image && \
apk del --no-cache .build-deps
{code}
Also, this is the test that Tika does internally to ensure that all the
dependencies are there
{code:java}
python3 -c "import numpy, matplotlib, skimage, _tkinter;"{code}
If you don't get any errors, then you're good
> Update rotation.py to work with python3 and a more modern matplotlib

> When I tried to work with rotation.py, I found that we should allow python to
> be python3 (not require an alias), and I found that rms_flat (once
> deprecated) has actually been removed in recent versions of matplotlib.
