Usage

ShareImage Can be easily integrated in any Python Project.
For example, in Flask:

from flask import Flask, render_template
from ShareImage import ShareImage

app = Flask(__name__)

@app.route('/')
def index():
    image = ShareImage(
        title="Home",
        cloudName="CLOUDINARY_CLOUD_NAME",
        imagePublicId="CLOUDINARY_IMAGE_ID"
    )
    return render_template('index.html', image=image)

@app.route('/posts/<string:slug>')
def posts(slug):
    image = ShareImage(
        title=bySlug.get(slug)['title'],
        cloudName="CLOUDINARY_CLOUD_NAME",
        imagePublicId="CLOUDINARY_IMAGE_ID"
    )
    return render_template('index.html', image=image)

if __name__=="__main__":
    app.run()

Now, you can use the image variable in any img Tag or og:image/twitter:image/image Meta Tags!
Note: CLOUDINARY_CLOUD_NAME and CLOUDINARY_IMAGE_ID are respectedly Your Cloudinary Cloud Name and Image Public Id (Including Folder Name) & the bySlug is a Special Variable to find specific posts in a Array of Dictionaries by Slug and it can be achieved by the following Code:

def build_dict(seq, key):
    return dict((d[key], dict(d, index=index)) for (index, d) in enumerate(seq))

bySlug = build_dict(ARRAY_OF_POSTS, key="KEY_OF_SLUG")

# Usage: bySlug(SLUG_OF_POST)['KEY_TO_FIND']

Utilites

By default ShareImage provides two useful Utility Functions.

Clean Text (clean_text)

It Cleanes a Text String and makes it URI-Compatible. Note: It uses Double-Escape for most Special Charecters to use it with Cloudinary. Example:

from ShareImage import clean_text

title = "A Test String"
print(clean_text(title)) # Will return A%2520Test%2520String

Join Tags (join_tags)

It Joins a Array of Tags to with # to use it as the tagline of ShareImage.
Example:

from ShareImage import ShareImage, join_tags

tags = [
	'Python',
	'Cloudinary'
]

image = ShareImage(
	cloudName = "zype",
	imagePublicId = "blog/Post-Image"
	title = "A Python Library to Generate Dynamic Share Images",
	tagline = join_tags(tags),
	taglineFont = "futura"
)
