Python Image generating script

A helpful tool for those in need of a large number of different images, with various sizes. Check out the Github page for the code, my blog post for some insights or just read the instructions below.

How to use it

After you download the archive from Github or just the backup script itself, you have to configure the config.json file by hand or you can use the online configurator.
All you have to do next is run python generate.py.

Settings

This is how the sample config file looks like:

            {
    "settings": {
        "total_images": 1,
        "output_path": "output",
        "filename": "sample_##index",
        "zfill": true,
        "format": "JPEG",
        "quality": 100,
        "background_color": "#000000",
        "size": {
            "width": 200,
            "height": 200,
            "ratio": 1
        },
        "text": "(##width x ##height)",
        "text_size": 20,
        "text_color": "#FFFFFF",
        "text_position": "center"
    }
}

total_images refers to the number of images you wish to generate. Has to be an integer.
output_path refers to the folder where the generated images will be saved. The default value is "output". The folder must exist before running the script.
filename refers to name structure of the saved image. You can use the dynamic keyword ##index, which will be automatically replaced with the image index (0 for the first image, 1 for the second, and so on).
zfill refers to zero-padding the index mentioned above, so you can preserve the alphabetical order. For 100 images, their names will regularly be image_0, image_1, etc. With zfill set to true you will get image_000, image_001, etc. Has to be a boolean.
format refers to image format. The possible values are JPEG and PNG.
quality refers to image quality, 0 for the lowest, 100 for the highest.
background_color refers to image's background color.
size refers to the image size.
text refers to the text written on the image (optional).
text_size refers to the font size in pixels of the text written on the image.
text_color refers to color of the text written on the image.
text_position refers to the position of the text written on the image. It can be top, center or bottom and comes with a 10 pixels margin.

Running the script

Open a terminal window and navigate to the location of the generate.py file. Then run python generate.py and watch the magic happen!
