thumbnails-readme --- Create thumbnails

Create thumbnails for raster and vector images in parent and its subdirectories and append them to the README.md file

---

Description 📋

The "thumbnails-readme" package is a simple library devoted to automatically generating thumbnails from a directory. It is explicitly designed to create thumbnails from Git folders. The thumbnails are shown in the README file of that Git folder. 📁🌐📸

Multi-pages PDFs are turned into .gif thumbnails 🔄

Current supported filetype extensions are: ".bmp", ".gif", ".ico", "jpeg", ".jpg", ".png", ".tga", ".tiff", ".webp", ".pdf" and ".svg"

How does it work? 💡

In the first step the program finds graphical material in your directories:

• ['fig1.pdf', 'fig2.pdf', 'fig3.pdf', 'fig4.pdf']

In the second step the program generates thumbnails for each material identified in folders.

In the third step the program appends thumbnails to the README file.

Additional dependencies

Windows

Windows users have to download poppler for Windows. Add poppler path in your Python file (see the main example).

poppler_path = path/to/your/poppler/bin/

for example: poppler_path = C:/Program Files/poppler-0.68.0/bin

Linux

Linux's users can install poppler-utils from the main repositories.

Example

# Maximum thumbnail size - lower the number, smaller the thumbnail
MAX_SIZE = (128, 128)

# PDF quality, lower the number, lower the quality
pdf_quality = 15

# Skiplist - which directories to ignore
skiplist = (
    ".git",
    )


# Path to your directory
path = os.getcwd()
path = os.path.dirname(path)

# Path to the folder, you want new thumbnails to be placed in
path_to_thumbnails_folder = Path(path + "/image_thumbnails")

# Path to README.md file to be written to
path_to_readme = Path(path + "/README.md")

Run the script

# Prepare thumbnails folder (check if exists, delete old thumbnails and create new ones)
thumbnails_readme.prepare_thumbnails_folder(path_to_thumbnails_folder)

# Prepare README.md file (check if exists, delete last modifications and place newly generated ones)
thumbnails_readme.prepare_readme(path_to_readme)

# Generate thumbnails
thumbnails_readme.crawl(path, path_to_readme, path_to_thumbnails_folder, MAX_SIZE, pdf_quality, skiplist, poppler_path)
