Prerequisites

To get started with Bole Linedrawing, you will need a Cognitive Actions API key and a basic understanding of how to make API calls.

Generate Line Drawing from Image

The Generate Line Drawing from Image action is designed to convert input images into stylized line drawings. This action is particularly useful for transforming photographs or complex images into simplified, artistic representations.

Purpose

This action solves the problem of needing quick and effective image stylization, making it easy to produce line art that can be used in various creative projects.

Input Requirements

To use this action, you need to provide:

  • imageUri: The URI of the input image, which should be in a valid format (e.g., https://example.com/image.png).
  • operationMode: An integer value between 1 and 8 that defines the stylization mode. By default, this is set to 1.

Example Input:

{
  "imageUri": "https://replicate.delivery/pbxt/McOfihZFQMkZjqncEnBFMvoW56kqEUuuu5dhW6ZEo7Wr8Jlx/92a3c9aeac2e43c88a8bdea358669de04490932753332960166829fb2597da2b.png"
}

Expected Output

The expected output is a URI link to the generated line drawing image, which can be easily incorporated into your projects.

Example Output:

[
  "https://assets.cognitiveactions.com/invocations/43b6778a-b2d9-4233-9707-4731c2864f1a/1041dc7e-ff64-47d6-a660-14d175eae2c9.png"
]

Use Cases for this Specific Action

  • Art and Design: Artists can quickly create line art from their sketches or images, allowing for rapid prototyping of ideas.
  • Web Development: Developers can enhance user interfaces with custom line drawings, giving a unique aesthetic to websites and applications.
  • Educational Materials: Create engaging visuals for presentations, infographics, and educational content by turning standard images into line drawings.
  • Print Media: Generate illustrations for books, magazines, or marketing materials that require a stylized touch.
