 * **Location**: lib/graphic/widget/base_support/image.h\n
 *\n
 * **Purpose**: Bitmap image rendering at arbitrary positions\n
 *\n
 * **Key Components**:\n

 *\n
 * @section widget_design_patterns Design Patterns\n
 *\n
 * @subsection pattern_init_render Initialize → Configure → Render\n
 *\n
 * All widgets follow this pattern:\n
 *\n
 * @code\n
 * 1. Initialize with base properties (Init function)\n
 * 2. Configure visual/behavioral properties (ops->set_property)\n
 * 3. Render (ops->immediate_draw or equivalent)\n
 * @endcode\n
 *\n
 * @subsection pattern_operation_tables Operation Tables\n
 *\n
 * Polymorphic behavior through function pointer tables enables:\n
 * - Multiple implementations per widget type\n
 * - Compile-time or runtime selection\n
 * - Future extensibility\n
 *\n
 * @subsection pattern_memory_ownership Caller Ownership\n
 *\n
 * - All structures stack/static allocated\n
 * - Caller owns: display device, bitmap data, item arrays\n
 * - Widgets reference, don't copy data\n
 * - Ensures deterministic memory usage\n
 *\n
 * @section widget_best_practices Best Practices\n
 *\n
 * @subsection bp_initialization Initialization\n
 *\n
 * - Call *_Init() for all widgets before using\n
 * - Initialize in order: dependencies first\n
 * - Keep structures valid for entire usage lifetime\n
 *\n
 * @subsection bp_drawing Drawing\n
 *\n
 * - Use deferred mode for multiple widgets\n
 * - Batch operations then single update()\n
 * - Minimize update calls in tight loops\n
 *\n
 * @subsection bp_animation Animation\n
 *\n
 * - Use 4-8 frames for UI feedback\n
 * - Use 16+ frames for smooth transitions\n
 * - Choose delays based on HAL tick resolution (25-50ms typical)\n
 *\n
 * @subsection bp_error_handling Error Checking\n
 *\n
 * - Always check return values from add_item() - may fail if full\n
 * - Always check return values from set_property() - property may not exist\n
 * - Validate coordinates before drawing (device->ops->setPixel may fail)\n
 *\n
 * @section widget_maintenance Documentation Maintenance\n
 *\n
 * When modifying widget code:\n
 *\n
 * 1. Update @file/@brief/@details comments\n
 * 2. Update member documentation if structure changes\n
 * 3. Add @example if new patterns emerge\n
 * 4. Update operation table documentation if callbacks change\n
 * 5. Regenerate Widget_UserGuide.md if major features added\n
 * 6. Update this Graphics_Widget_Documentation page\n
 *\n
 * @section widget_integration Integration with Core Graphics\n
 *\n
 * Widgets integrate seamlessly with core Graphics Device:\n
 *\n
 * @verbatim\n
 * Core Graphics Features:          Widget Support:\n
 * - Immediate/Deferred Mode   →    All widgets respect device mode\n
 * - Device abstraction        →    All widgets use CFBD_GraphicDevice\n
 * - Animation framework       →    Built-in CFBD_BaseAnimation support\n
 * - Multiple device types     →    Works with any device (OLED, LCD, etc.)\n
