Dockerfile for automated DockerHub build of exrtools on Ubuntu.
The Dockerfile here installs exrtools on Ubuntu. This gives us a handy Docker image for distributing exrtools.
It might be nice to build on Alpine rather than Ubuntu, to get a smaller image. it would take more config to get the build tools and OpenEXR installed under Alpine.
An alternative to exrtools is ImageMagick but this does not have high dynamic range enabled by default. So again, it would take more work.
Invoke this image just like you would invoke exrtools. For example:
docker run ninjaben/exrtools exrnormalize input.exr output.exr [ maxval ] docker run ninjaben/exrtools exrtopng input.exr output.png docker run ninjaben/exrtools jpegtoexr input.jpg output.exr
And so on.
