Start use

You should make sure the libtiff submodule is cloned.

git clone --recursive https://github.com/google/sandboxed-api

mkdir -p build && cd build
cmake .. -DSAPI_ROOT=/path/to/sapi_root
make -j8

You should add -DLIBPNG_SAPI_ENABLE_EXAMPLES=ON to use the example.
run PNG to PNG:

./examples/pngtopng /absolute/path/to/input/image.png /absolute/path/to/output/image.png

run RGB to BGR:

./examples/rgbtobgr /absolute/path/to/input/image.png /absolute/path/to/output/image.png

Examples of input and output can be found in images.

PNG to PNG:
input: images/pngtest.png
output: images/pngtopng_pngtest.png

RGB to BGR:
input: images/red_ball.png
output: images/rgbtobgr_red_ball.png

You should add -DLIBPNG_SAPI_ENABLE_TESTS=ON to use tests and do:

cd tests
ctest .
