Release Overview

Release v1.4.1.0

This is a major update to Pyicon-Editor, bringing deep native Windows integration, a completely revamped copy/paste workflow, vital data-loss protections, and significant UI and stability improvements.

New Features & Workflow Enhancements

• Windows EXE/DLL Icon Extraction (#8):
  • Implemented native Windows resource extraction using PrivateExtractIconsW.
  • Interactive UI: Opening an executable now spawns a visual IconPopup modal, allowing you to browse and select specific embedded icons from a scrollable grid.
  • High-Res & Legacy Support: Integrated cascading size resolution (starting at 256x256) and raw hbmMask parsing to guarantee high-quality, uncorrupted extraction of both modern and legacy transparent icons.
• Native System Clipboard Integration:
  • Full two-way support for the Windows OS clipboard. You can now Copy/Paste images directly between the editor and external applications (e.g., Photoshop, Discord, MS Paint).
  • Simultaneously pushes both DIB (for legacy app compatibility) and PNG (for modern alpha-transparency) formats to system memory.
  • Smart File Interception: Simply paste an image file path copied directly from Windows Explorer to automatically import it onto the canvas.
• MS Paint-Style Selection Workflow:
  • Added Select All (Ctrl+A) capabilities.
  • Pasting an image now spawns it as a dynamic, floating selection perfectly aligned to the top-left of your active viewport, automatically activating the Move tool so you can position it immediately.

Data Safety & Core Fixes

• Unsaved Changes Protection: The editor now actively tracks canvas modifications. Interacting with Exit, New Canvas, or Open Image while work is unsaved will spawn a safety prompt, completely preventing accidental data loss.
• Double-Undo & History Overhaul: Fixed a frustrating off-by-one stack bug and halted Tkinter event propagation bleeding (return "break"), ensuring that hitting Ctrl+Z perfectly steps back exactly one drawing stroke at a time.
• 64-bit Memory Safety: Explicitly defined 64-bit ctypes handles for all native Windows API calls, permanently fixing silent memory truncation crashes during clipboard operations.

UI & Quality of Life Improvements (#9, #10)

• Smooth Slider Snapping: All toolbar sliders (Brush Size, Alpha, Tolerance, Zoom) now feature instant click-to-snap and smooth hold-to-drag adjustments, bypassing clunky default Tkinter "page jumping".
• Horizontal Scrolling: Added native support for horizontal trackpad panning and Shift + MouseWheel scrolling across the canvas.
• Theming Engine Isolation: Fixed global Dark Mode/System Theme conflicts. The new IconPopup utilizes custom, isolated styles to ensure a clean, native Windows appearance while preventing visual "border bleeding" on scrollbars and buttons when Dark Mode is active.
• Graceful Cancellation: All dialogs and extraction operations now handle user cancellation (clicking 'X') cleanly, silently aborting operations without throwing application errors.
