screenshot-framer 0.4.0

A robust, Pillow-based alternative to fastlane frameit for composing premium mobile marketing screenshots.

screenshot-framer

A robust, Python-based CLI tool to composite premium marketing screenshots for iOS and Android applications.

screenshot-framer was built as a lightweight, flexible alternative to fastlane frameit. It bypasses the common system-level ImageMagick/FreeType font rendering failures by relying entirely on Python's self-contained Pillow library for image composition, device rounding, drop shadows, and responsive text overlay.

Features

• No ImageMagick Required: Pure Python image manipulation using Pillow.
• Cross-Platform Auto-Detection: Dynamically detects iOS (flat directories) and Android (nested phoneScreenshots, sevenInchScreenshots, tenInchScreenshots) architectures and automatically applies the correct scaling and border radii.
• Dynamic Text Scaling: Automatically scales down long titles so they never clip off the edge of your marketing canvas.
• Modern Device Styling: Instead of forcing clunky hardware bezels onto your UI, it elegantly rounds the corners of your raw screenshots and applies a premium Gaussian drop-shadow, floating it over your chosen background.
• Fastlane Compatible: Can parse your existing title.strings and keyword.strings files directly.

Installation

pip install screenshot-framer

Usage

Create a configuration JSON file (e.g. framer_config.json) in your project:

{
  "base_dir": "./fastlane/metadata/android/en-US",
  "background": "./fastlane/metadata/android/en-US/background.png",
  "title_font": "/System/Library/Fonts/SFCompact.ttf",
  "keyword_font": "/System/Library/Fonts/SFCompact.ttf",
  "title_color": "#ffffff",
  "keyword_color": "#c8c8c8",
  "device_radius_phone": 80,
  "device_radius_seven_inch": 70,
  "device_radius_tablet": 60,
  "shadow_radius": 50,
  "shadow_opacity": 150,
  "screenshot_scale": 0.70,
  "exclude_files": ["01_dashboard.png", "raw_marketing.png"],
  "fallback_title": "Upnext",
  "default_disclaimer": "TV SHOW METADATA PROVIDED BY TVMAZE.COM"
}

Configuration Options

• screenshot_scale: Defines how large the device will appear relative to the background canvas height (e.g., 0.70 means 70% of the canvas height).
• exclude_files: An array of substrings. Any raw screenshot containing these strings in its filename will be skipped.
• device_radius_*: Defines the corner roundness depending on whether the detected screenshot belongs to a phone, 7-inch tablet, or 10-inch tablet.

Then run the tool from your terminal:

screenshot-framer --config framer_config.json

How It Works

1. Discovery: The script intelligently scans the base_dir and common fastlane subdirectories (phoneScreenshots, sevenInchScreenshots, tenInchScreenshots).
2. Device Detection: It determines the device type (Phone, 7-inch Tablet, 10-inch Tablet) based on the containing folder or the filename (perfect for iOS devices like iPad Pro).
3. Matching: It maps your raw screenshots to the translated strings in title.strings.
4. Compositing: It scales your background, frames your screenshot with rounded corners, adds a premium drop shadow, and responsively fits your Title and Keyword text.
5. Export: It outputs _framed.png files ready for the App Store and Google Play.
