Image Projective Transformation

Apply advanced projective transformation for complex 3D surface mapping and projection effects

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-projective' \
  -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-projective' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'matrixRows=Enter 3x3 transformation matrix (e.g., [[1, 0, 0], [0, 1, 0], [0.001, 0.002, 1]])...' \
  -F 'interpolation=bilinear' \
  -F 'background=transparent' \
  -F 'format=png' \
  -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-projective

Parameters

Name	Type	Required	Description
imageFile	fileupload required	Yes	Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) for projective transformation
matrixRows	textarea	Yes	3x3 projective transformation matrix in homogeneous coordinates. Format: [[a,b,c],[d,e,f],[g,h,i]]
interpolation	select	No	Method for interpolating pixel values during transformation
background	text	No	Background color for empty areas (hex #RRGGBB or #RRGGBBAA, or color name)
format	select	No	Output format for the result image (PNG recommended for transparency)
quality	number	No	Output quality for lossy formats

File-type parameters must be uploaded first via POST /upload/image-projective, then the returned filePath is passed to the corresponding file field.

Response format

File result

JSON

{
  "filePath": "/public/processing/randomid.ext",
  "fileName": "output.ext",
  "contentType": "application/octet-stream",

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-projective": {
      "name": "image-projective",
      "description": "Apply advanced projective transformation for complex 3D surface mapping and projection effects",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-projective",
      "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-projective",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "matrixRows": "Enter 3x3 transformation matrix (e.g., [[1, 0, 0], [0, 1, 0], [0.001, 0.002, 1]])...",
  "interpolation": "bilinear",
  "background": "transparent",
  "format": "png",
  "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.
