How do I get set up?

Clone the remote git repository, this should also give you the master branch.

git clone https://github.com/davidpshea/8itest.git
Switch to the project directory.

cd 8itest
If not already done, let cmake know where the QT cmake package configuration is by setting the environment variable CMAKE_PREFIX_PATH For instance, for my Mac, this would be

export CMAKE_PREFIX_PATH=/Users/davidshea/source/qt/5.15.0/clang_64
Initialise the build using cmake

cmake . -B build
Build the app, for example, this will build the release version.

cmake --build build --config release
You should then have an executable 8i in the build directory. You should run this in the 8itest directory (where the source files are) so the app knows where the background image is, as it looks for the folder givenfiles

./build/8i

When the app runs, there's 5 buttons on the left, and a slider.

Load Image Loads an image to be background removed.
Load Backdrop Loads a blank backdrop that's the background without anything to remove.
Save Image Saves the original image, debayered, and orientated as seen in the app as a PNG file.
Save Foreground Saves the background removed image, orientated as seen in the app as a PNG file.
Rotate 90 Rotates the images 90 degrees clockwise on each click.
The slider threshold controls how exact the match between background pixels has to be before it's considered background.
You can resize the window and the images will resize with it.
There's some sample output in exampleoutput
The original images are held in givenfiles.
