A simple python image difference library. It returns the % difference of the
image. Additionally, it also saves the visual differences to a file called
diff.png.
Here is a sample image of the visual difference:
The difference will be in red.
| Left-hand Side | Difference between left and right images | Right-hand Side |
|---|---|---|

To use the library you need to build the .so. Here is the go building command:
go build -o lib.so -buildmode=c-shared library.go
Usage of the library is really simple. The only exported function is compare.
import imagediff
with open("a.png", 'rb') as a:
with open("b.png", 'rb') as b:
difference = library.compare(a.read(), b.read())
print(difference)
