image-merge is a command line program that merges multiple images using a variety of template options.

• outputs standard 4" X 6" (300dpi) jpeg images for printing
• automatically rotates and re-sizes images to fit

• combines 2, 3, or 4 source images
• combines images by setting a maximum height in cm

Clone master branch. From a terminal inside the cloned directory type:

python setup.py install

image-merge --help

test images are created and saved to /tmp/img#-0001.img where # is the number of images per page.

1. install py.test:

   pip install pytest

2. from the root directory run the tests:

   py.test

If you need to change the output directory, set the environment variable IMAGE_MERGE_TEST_DIR to the directory you want.

For example:

export IMAGE_MERGE_TEST_DIR="/home/username/my-dir/"    
py.test

or

IMAGE_MERGE_TEST_DIR="/home/username/my-dir/" py.test
