Gemini 浮水印移除工具

移除 Google Gemini AI 生成圖片中的浮水印。完全在本地執行，無需上傳圖片至任何伺服器。

使用方式

方式一：npx（推薦）

# 直接執行，無需安裝
npx gemini-watermark-remove <圖片路徑>

# 範例
npx gemini-watermark-remove image.png
npx gemini-watermark-remove image.png --output clean.png
npx gemini-watermark-remove image.png --mode large --gain 1.5

方式二：Node.js（npx 失敗時使用）

若 npx 執行失敗，可改用 Node.js 直接執行腳本：

# 1. 先安裝相依套件
cd <skill目錄>
npm install

# 2. 執行腳本
node scripts/remove-watermark.js <圖片路徑>

# 範例
node scripts/remove-watermark.js image.png
node scripts/remove-watermark.js image.png --output clean.png
node scripts/remove-watermark.js image.png --mode large --gain 1.5

參數

參數	說明	預設值
`-o, --output`	輸出檔案路徑	`{檔名}_clean.{副檔名}`
`-m, --mode`	遮罩模式:`auto`, `small`, `large`	`auto`
`-g, --gain`	Alpha 增益值 (1.0-3.0)	`1.0`

批次處理

Get-ChildItem "*.png" | ForEach-Object { npx gemini-watermark-remove $_.FullName }

技術原理

逆向 Alpha 混合演算法：原始像素 = (當前像素 - α × 浮水印顏色) / (1 - α)

≤1024px: 48×48 遮罩，邊距 32px
>1024px: 96×96 遮罩，邊距 64px
