Apply affine transformation for scaling, rotation, shearing, and translation

file· File resultOpen tool

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-affine' \
  -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-affine' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'scaleX=1.0' \
  -F 'scaleY=1.0' \
  -F 'angle=0' \
  -F 'shearX=0' \
  -F 'shearY=0' \
  -F 'translateX=0' \
  -F 'translateY=0' \
  -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-affine

Parameters

Name	Type	Required	Description
imageFile	fileupload required	Yes	Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) for affine transformation
scaleX	range	No	Horizontal scaling factor (0.1 to 10.0, 1.0 = original size)
scaleY	range	No	Vertical scaling factor (0.1 to 10.0, 1.0 = original size)
angle	range	No	Rotation angle in degrees (-180 to 180, 0 = no rotation)
shearX	range

Response format

File result

JSON

{

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-affine": {
      "name": "image-affine",
      "description": "Apply affine transformation for scaling, rotation, shearing, and translation",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-affine",
      "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-affine",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "scaleX": "1.0",
  "scaleY": "1.0",
  "angle": "0",
  "shearX": "0",
  "shearY": "0",
  "translateX": "0",
  "translateY": "0",
  "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).

File parameters accept a public file URL only (https://…). Local paths, data: URIs, and Base64 strings are not supported.
