为图片添加对角水印，可自定义角度、大小、透明度和沿对角线位置
用三种语言从你的代码中调用此工具。
# 1) Request a presigned URL → returns { uploadUrl, storageKey }
curl -X POST 'https://api.elysiatools.com/api/upload/presign/image-watermark-diagonal' \
-H 'Content-Type: application/json' \
-d '{"filename":"imageFile.ext","contentType":"application/octet-stream","size":12345}'
curl -X POST 'https://api.elysiatools.com/api/upload/presign/image-watermark-diagonal' \
-H 'Content-Type: application/json' \
-d '{"filename":"watermarkImageFile.ext","contentType":"application/octet-stream","size":12345}'
# 2) PUT the file bytes directly to the presigned uploadUrl
curl -X PUT '<presigned uploadUrl>' \
--data-binary @/path/to/file.ext
# 3) Call the tool, passing the returned storageKey for each file field
curl -X POST 'https://api.elysiatools.com/zh/api/tools/image-watermark-diagonal' \
-F 'imageFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
-F 'watermarkImageFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
-F 'diagonalAngle=45' \
-F 'scale=0.3' \
-F 'opacity=0.5' \
-F 'spacing=100' \
-F 'margin=50' \
-F 'blendMode=over' \
-F 'repeatCount=3' \
-F 'centerOnDiagonal=false' \
-F 'autoFit=false' \
-F 'stretchToFit=false'以 JSON 形式 POST 提交输入参数。文件类型参数需先单独上传。

}将此工具加入你的 Model Context Protocol 服务，让 AI 智能体可以列出并调用它。
将以下内容加入你的 MCP 客户端配置：
{
"mcpServers": {
"elysiatools-image-watermark-diagonal": {
"name": "image-watermark-diagonal",
"description": "为图片添加对角水印，可自定义角度、大小、透明度和沿对角线位置",

}
}
}连接到 SSE 端点后，列出已开放的工具：
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}通过工具 id 调用，参数由其参数表构建：
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "image-watermark-diagonal",
"arguments": {
