# Calendar Generator Flask App
|
||||
|
||||
This Flask application generates a web-based calendar view with images and associated texts for each day. It's designed to read images and texts from specified directories and display them in a calendar format. The web-based pages can be printed to a pdf-file. This is easy, because every browser application has the option to print a page to a pdf-file. Per DIN A4 page 4 days get displayed.

# Calendar Generator PDF App

3. Access the calendar in a web browser at `http://127.0.0.1:5000/`.
|
||||
3. "PDF created successfully" shoud appear, then you can access the pdf file which is in the same directory as the script.
|
||||
|
||||
## How It Works
|
||||
|
||||
- The application serves a web page displaying a calendar.
|
||||
- Each day on the calendar can have an image and a text associated with it.
|
||||
- Images are read from `static/images/`, and text files are from `texts/`.
|
||||
- Images are read from `images/`, and text files are from `texts/`.
|
||||
- Files are matched based on their filenames, formatted as `YYYY-MM-DD`.
|
||||
- The calendar is dynamically generated based on available images and texts.
|
||||
- If an image or text is not available for a specific day, it will be displayed without that content.

|
||||
## Notes
|
||||
|
||||
- Text for each day should be concise. Lengthy texts may be truncated in the display to maintain the layout of the calendar.
|
||||
- You can customize the appearance and behavior of the calendar by modifying the HTML, CSS, and Flask application logic.
