Image Shear

Apply shear transformation to create slanted or skewed images. Visualize shear matrices and see how they distort the image geometry.

file· File resultOpen tool

Quick start

Call this tool from your code in three languages.

cURL
# 1) Request a presigned URL → returns { uploadUrl, storageKey }
curl -X POST 'https://api.elysiatools.com/api/upload/presign/image-shear' \
  -H 'Content-Type: application/json' \
  -d '{"filename":"imageFile.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/en/api/tools/image-shear' \
  -F 'imageFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
  -F 'shearX=0' \
  -F 'shearY=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-shear

Parameters

NameTypeRequiredDescription
imageFilefileupload requiredYesUpload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) for shear transformation
shearXrangeYesHorizontal shear factor (-2.0 to 2.0, 0 = no shear, positive = rightward tilt)
shearYrangeYesVertical shear factor (-2.0 to 2.0, 0 = no shear, positive = downward tilt)
backgroundtextNoBackground color for transparent areas (hex #RRGGBB or #RRGGBBAA, or color name)
formatselectNoChoose output format or keep original. PNG recommended for transparency
qualitynumberNoOutput quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size
File-type parameters must be uploaded first via POST /upload/image-shear, then the returned filePath is passed to the corresponding file field.

Response format

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-shear": {
      "name": "image-shear",
      "description": "Apply shear transformation to create slanted or skewed images. Visualize shear matrices and see how they distort the image geometry.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-shear",
      "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-shear",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "shearX": "0",
  "shearY": "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.
