Overview

This node performs image cropping operations. It allows users to specify the cropping area by defining the starting X and Y coordinates, as well as the width and height of the crop region. The node supports input images from file paths, base64 strings, or binary data, and can output the cropped image either saved to a file or as binary data. This is useful for scenarios where you need to extract a specific portion of an image, such as focusing on a subject or removing unwanted parts.

Use Case Examples

  1. Cropping a product image to highlight the product only.
  2. Extracting a face from a group photo for profile pictures.
  3. Removing borders or margins from scanned documents.

Output

JSON

  • error - Error message if the operation fails
  • success - Boolean indicating if the operation was successful
  • operation - The image processing operation performed (crop)

Dependencies

  • sharp library for image processing

Troubleshooting

  • Ensure the source image path or input data is correct and accessible.
  • Verify that the crop coordinates and dimensions are within the bounds of the source image.
  • Check that the output path is writable if saving to a file.
  • If using binary data input, confirm the binary property name is correct and contains valid image data.
  • Common errors include file not found, invalid image format, or out-of-bound crop dimensions. These can be resolved by correcting the input parameters and ensuring file system permissions.
