Placeholder Service

This is a Python script that creates images from text input received through HTTP requests.

Features

• Generates images with user-provided text.
• Supports various image formats (PNG by default).
• Allows customization of font, text color, background color, font size, and alignment.
• Fetches fonts from Google Fonts repository if not found locally.

Usage

Server:

• Save the script as placeholder_service.py.
• Install required libraries:

pip install -r requirements.txt

Run the server:

python placeholder_service.py

This will start the server on http://localhost:9845 by default.

Client:

You can use any tool that can send HTTP requests, such as curl or a web browser. Here's an example using curl:

curl "http://localhost:9845/?text=YOUR_TEXT&font=FONT_NAME.ttf&color_text=COLOR_CODE&color_bg=COLOR_CODE&font_size=SIZE&font_align=ALIGN&img_format=FORMAT"

# Replace with your desired options:
#  - text: The text to be displayed on the image (required)
#  - font: Path to a font file (optional, defaults to 'FrederickatheGreat-Regular.ttf')
#  - color_text: Text color in hex code (e.g., 'FF0000' for red, optional, defaults to '1400FF')
#  - color_bg: Background color name or hex code (optional, defaults to 'white')
#  - font_size: Font size in pixels (optional, defaults to 200)
#  - font_align: Horizontal text alignment ('left', 'center', or 'right', optional, defaults to 'center')
#  - img_format: Image format (e.g., 'png', 'jpg', etc., optional, defaults to 'png')

Example:

curl "http://localhost:9845/?text=Hello\nWorld!&color_text=00FF00&color_bg=0000FF"

This will download an image with the text "Hello\nWorld!" in green color and in blue background.

Configuration

Font Download:

By default, the server tries to download fonts from the Google Fonts repository if the requested font is not found locally. This functionality requires an internet connection.

Logging:

The script uses Python's built-in logging module. You can configure logging behavior by creating a separate logging configuration file.

Development

Feel free to modify the script to suit your specific needs. You can add functionalities like:

• Additional image processing options.
• User authentication for secure text submission.
• Support for different text formats (e.g., HTML).
