FicImageScript 4.1.1

Installation with PIP

1. Install FicImage using pip install FicImageScript.

2. After installation, run the program using ficimage -p path/to/epub -c path/to/ficimage/json where path/to/epub is the path to the FicHub epub you want to add images to and path/to/ficimage/json is the path to a file called ficimage.json . ficimage.json lets you configure FicImage. See more in the configuration section below.

(virt) nonso@HPEnvy:~/Documents/Code$ ficimage -h
 usage: main.py [-h] [-p PATH_TO_EPUB] [-c CONFIG_FILE_PATH] [-d] [-v] [-r RECURSIVE]

 Update a FicHub epub file with images.

 options:
   -h, --help            show this help message and exit
   -p PATH_TO_EPUB, --path_to_epub PATH_TO_EPUB
                         The path to the FicHub epub file.
   -c CONFIG_FILE_PATH, --config_file_path CONFIG_FILE_PATH
                         The path to the ficimage.json file.
   -d, --debug           Enable debug mode.
   -v, --version         Prints out the current version and quits
   -r RECURSIVE, --recursive RECURSIVE
                         This will update all files in the directory path given and its subdirectories

Image Support

FicHub creates EPUB 3.3 files, which means that FicImage only save images in the following file format:

• JPEG

• PNG

• GIF

• WEBP

• SVG

See the Core Media Types Section of the EPUB Version 3.3 Specification for more information.

While FicImage can save SVG images, it can not compress them because SVGs are not supported by Pillow.

FicImage uses Pillow for image manipulation and conversion.

By default, FicImage will try and save all non-animated images as JPEGs.

The only animated images that FicImage will save are GIFs and WEBPs.

FicImage does little to no processing on GIFs and WEBPs images. This is to avoid breaking the animation.

If FicImage can not download an image, it leaves the image url paragraph the same way it met it.

To configure image support, you will need to create a file called ficimage.json. See the section below for more information.

Configuration

FicImage comes with a configuration file that allows you to customize the program to your liking.

The configuration file is in the JSON file format and contains the following options:

• compress_images: A boolean that tells FicImage whether to compress images. This is only supported for jpeg and png images.

• default_image_format: A string that tells FicImage what default format to convert and save images in. This is only supported for jpeg and png images.

• max_image_size: An integer that tells FicImage the maximum size of an image in bytes. If an image is larger than this value, FicImage will compress it.

FicImage checks for a configuration file in the given directory path. If no directory path is given, FicImage checks the current directory and then the Operating System’s home directory.

If it does not find one, it uses the following defaults:

{
    "compress_images": true,
    "default_image_format": "JPEG",
    "max_image_size": 100000
}

Note: The compress_images key is a boolean and can only be true or false. Booleans in JSON are written in lowercase.

Note: If the default_image_format key does not exist, FicImage will default to jpeg. The two image formats are jpeg and png. The default_image_format key is case-insensitive.

Note: The compress_images key tells FicImage to compress images. This is only supported for jpeg and png images. This also goes hand-in-hand with the max_image_size key. If the compress_images key is true but there’s no max_image_size key, FicImage will compress the image to a size less than 1MB (1000000 bytes). If the max_image_size key is present, FicImage will compress the image to a size less than the value of the max_image_size key. The max_image_size key is in bytes.

If compress_images is false, FicImage will ignore the max_image_size key.

Warning: Compressing images might make the image quality worse.

Warning: max_image_size is not a hard limit. FicImage will try to compress the image to the size of the max_image_size key, but it might not be able to compress the image to the exact size of the max_image_size key.

Warning: max_image_size should not be too small. For instance, if you set max_image_size to 1 000, FicImage will probably not be able to compress the image to 1 000 bytes (1 KB). If you set max_image_size to 1 000 000, FicImage will probably be able to compress the image to 1 000 000 bytes (1 MB).

Warning: FicImage will not compress GIFs or WEBPs, that might damage the animation.
