Montafons

Python library to generate an image collage from other images. I mainly use it to generate horizontal wallpapers from multiple vertical images, but feel free to use it for any other purpuse. It is optimized for speed by using multiple threads to render images in paralel.

                 [-top BORDER_TOP] [-right BORDER_RIGHT] [-bottom BORDER_BOTTOM]
                 [-left BORDER_LEFT] [-smin SEPARATION_MIN] [-smax SEPARATION_MAX]
                 [-mw WIDTH_MIN] [-c CORRECTION_MAX] [-t] [-rn]
                 [images ...]

Usage as a library

from montafons import Montafons

example_images = ['a.png', 'b.jpg', 'c.png']
params = {
    "width": 1080,
    "height": 1920,
    # More parameters can be added, see the parametres section
}

mf = Montafons(**params)

for image in example_images:
    mf.add(image)

mf.make("output.png")
