Key Features
- Multi-layer Gerber RS-274X rendering — independent opacity, visibility toggle, and color-coded layers
- ZIP batch import with automatic decompression, macOS metadata filtering, and multi-file drag & drop
- Smart layer identification from filenames — auto-detects copper, solder mask, silkscreen, solder paste, drill, and board outline
- Precision measurement tools — single and continuous modes, real-time live preview during drag, distance, angle, dx/dy readout in mil or mm
- Real-time cross-probe cursor — continuous coordinate tracking across all layers on the canvas
- Customizable grid overlay — none, lines, dots, or crosshair modes; aligns to Gerber origin or bounding box
- Zoom controls — zoom in/out buttons, fit-to-view, zoom percentage input with scroll wheel support and expression evaluation
- Canvas flip / mirror view toggle for inspecting board from different perspectives
- Layer management panel — individual visibility eye icons, per-layer opacity sliders, global opacity control
- Automatic 32-color palette assignment per layer for clear visual distinction

Frequently Asked Questions
什麼係 Gerber 檔案？
Gerber RS-274X 係 PCB 製造業標準檔案格式，用於描述電路板嘅銅層、阻焊層、絲印層同鑽孔數據。
呢個 Gerber 檢視器真係免費？
係，完全免費。唔使註冊，唔使上傳到伺服器，冇檔案大小限制。所有處理喺瀏覽器本地完成。
支援邊啲 CAD 工具？
支援 19 種 PCB 設計工具，包括 KiCad、Altium Designer、Autodesk Eagle、Cadence OrCAD/Allegro、DipTrace、gEDA、Siemens PADS、Proteus 等。
可以同時睇多個圖層嗎？
可以。支援多圖層疊加顯示，每個圖層可獨立調節唔透明度、切換可見性，並自動分配顏色以便區分。
我嘅檔案會上傳到伺服器嗎？
唔會。所有數據喺瀏覽器本地用 JavaScript 處理，檔案唔會離開您嘅裝置，完全保護隱私。
