LightCapture Area Screenshot

Lightshot for Linux v2.0.0 is a native PyQt5 screen capture, instant inline
annotation, perceptual dHash visual similarity analyzer, and share package
exporter engineered for Linux desktops with 100% real X11/Wayland screen
capture and image processing.

KEY FEATURES:
• Fast Screen / Region Capture & Instant Floating Markup Toolbar: Captures real full screen or custom rectangle (x, y, width, height) via QGuiApplication.primaryScreen().grabWindow(0) and renders real inline annotations directly onto the QImage buffer (Pen/Freehand Draw, Straight Line, Arrow Callout, Rectangle HighlightBox, Yellow Marker Highlighter, Text Label Overlay, and Crop to Selection).
• Visual Similarity Histogram Analyzer & Share Package Exporter: Computes real 64-bin RGB color histograms, 64-bit hex perceptual dHash (difference hash from real 9x8 grayscale pixels), Hamming distance visual similarity comparison, SHA-256 checksums, and exports real Data-URI / HTML / Markdown share packages to /tmp/lightshot-captures.
• Capture & Annotation History Manager: Scans /tmp/lightshot-captures and /usr/share/pixmaps for real image files, inspecting Filename, Real Path, Dimensions (WxH), Perceptual dHash, Byte Size, SHA-256, and Modified Time.
