I'll create a drawing application similar to Excalidraw with a top toolbar, expandable left sidebar for tool options, and a full-screen canvas. The interface will match the design and functionality shown in your screenshots.

I've created a drawing application that closely mimics Excalidraw's interface with the following features:

Key Features:

1. Top Toolbar: Contains all drawing tools with proper icons and selection states

2. Tool Options Sidebar: Appears on the left when tools are selected, featuring:

   • Stroke color picker with the same color palette
   • Background color options
   • Stroke width selection
   • Edge style options
   • Opacity slider
3. Full-Screen Canvas: Takes up 100% of the viewport and responds to window resizing
4. Welcome Message: Displays the Excalidraw-style branding and instructions
5. Bottom Controls: Zoom controls positioned at the bottom left
6. Responsive Design: Works on both desktop and mobile devices

Technical Implementation:

• Uses React hooks for state management
• Canvas automatically resizes with the window
• High z-index toolbar stays on top
• Proper tool selection and visual feedback
• Color palette matches Excalidraw's design
• Smooth transitions and hover effects

The interface is fully functional for tool selection and option changes. To add actual drawing functionality, you would need to implement canvas drawing logic with mouse/touch event handlers.

I'll refactor the drawing application using Vue 3 with TypeScript and match the drawing options popup exactly as shown in your image.

I've successfully refactored the drawing application using Vue 3 with TypeScript and matched the drawing options popup exactly as shown in your image. Here are the key improvements:

Key Features:

1. Vue 3 Composition API: Using <script setup> with TypeScript for better type safety

2. Exact UI Match: The left sidebar now matches your image with:

   • 描边 (Stroke) - 6 color swatches in a grid
   • 背景 (Background) - lighter colors with transparent option
   • 描边宽度 (Stroke Width) - vertical buttons with line thickness indicators
   • 边框样式 (Edge Style) - solid, dashed, and dotted line options
   • 线条网格 (Line Roughness) - wavy line variations using SVG paths
   • 边角 (Corners) - sharp, rounded, and circular corner options
   • 透明度 (Transparency) - custom styled slider from 0-100
   • 图层 (Layers) - layer management buttons with proper icons

3. TypeScript Integration:

   • Proper type definitions for all tools, colors, and configurations
   • Type-safe reactive references and methods
   • Interface definitions for complex objects
4. Chinese Labels: All labels match the Chinese text from your image
5. Responsive Design: Canvas automatically resizes and maintains full viewport coverage
6. Proper State Management: Vue 3 reactive system handles all tool selections and options

The interface now perfectly matches the Excalidraw design you provided, with all the drawing options laid out exactly as shown in your screenshot.
