Rounded Window Capture

A Linux X11 alternative to WinSnap. Independent open-source project, not
affiliated with or endorsed by NTWind Software.

Window enumeration, crosshair X11 pointer picking, and QScreen.grabWindow
capture operate on X11 and XWayland windows; Wayland-native windows cannot
be enumerated or captured by external X11 clients.

FEATURES
• Window Capture & Visual Stylist: enumerate live X11 windows or pick any
target with an interactive X11 crosshair cursor, capture clean window pixels
or full screen with optional delay timer, apply anti-aliased rounded
corners (0-32px), multi-pass drop shadow blur, transparent or gradient
canvas padding, reflection, and watermark stamp. Save PNG/JPG or copy
directly to clipboard.
• Quick Annotator: interactive vector toolbar directly over captured frames
with Arrow, Rectangle Box, Highlight Marker, Pixelate/Redact region tool,
and Text Labels with Undo/Redo history baked cleanly into exported images.
• Capture Library & Batch Auto-Style: browse real saved captures in your
Pictures folder, load captures back into the editor, and batch-apply saved
corner, shadow, and background presets across multiple PNG files.
