Quick start

Call this tool from your code in three languages.

cURL

# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/image-rotation-matrix' \
  -F 'file=@/path/to/imageFile.ext'

# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/image-rotation-matrix' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'angle=45' \
  -F 'background=transparent' \
  -F 'format=original' \
  -F 'quality=95'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP

POST https://api.elysiatools.com/en/api/tools/image-rotation-matrix

Parameters

Name	Type	Required	Description
imageFile	fileupload required	Yes	Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) for rotation matrix transformation
angle	range	Yes	Rotation angle in degrees (-180 to 180, 0 = no rotation). Positive = clockwise, negative = counter-clockwise
background	text	No	Background color for transparent areas (hex #RRGGBB or #RRGGBBAA, or color name)
format	select	No	Choose output format or keep original. PNG recommended for transparency

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-image-rotation-matrix": {
      "name": "image-rotation-matrix",
      "description": "Apply rotation transformation using rotation matrix mathematics. See the 2x2 rotation matrix in action and understand the trigonometric principles behind image rotation.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-rotation-matrix",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "image-rotation-matrix",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "angle": "45",
  "background": "transparent",
  "format": "original",
  "quality": 95
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
