ScrollSnap

ScrollSnap is an open-source macOS application designed to capture scrolling screenshots with a customizable selection area and menu interface. It allows users to define a capture region, take stitched scrolling screenshots, and save them to various destinations (e.g., Desktop, Clipboard, Preview). Built with Swift and leveraging AppKit and ScreenCaptureKit, ScrollSnap provides a sleek overlay-based UI for precise control.

Features

• Customizable Selection Area: Resize and drag a selection rectangle to define the capture region.
• Scrolling Capture: Automatically stitches multiple screenshots into a single image for capturing long content.
• Keyboard Shortcut: Press Return while the overlay is active to start or stop scrolling capture.
• Interactive Menu: Includes options to capture, save, reset positions, or cancel, with a draggable interface.
• Thumbnail Preview: Displays a draggable thumbnail of the captured image with swipe-to-save or right-click options.
• Save Destinations: Supports saving to Desktop, Documents, Downloads, Clipboard, or opening in Preview.
• Settings: Adjust language and reset selection and menu positions via the native settings window (Command + ,).

Multi-Language Support

ScrollSnap currently supports English, Simplified Chinese, French, German, Japanese, Korean, Romanian, Spanish, and Turkish.
