IMAGE_CROP

ImageCropStep is used to crop an image to the specified rectangular region. The crop region may be specified in one of two ways:

1. Via a bounding box, or

2. Via a list of points of length 2, containing the top-left and bottom-right crop locations.

These may be specified statically (i.e., fixed crop region) via cropBox or cropPoints property, or dynamically via cropName (which may specify a bounding box or list of point in the input data instance).

Furthermore, the bounding box and corner point coordinates may be specified in terms of either pixels or fraction of image - specified via the coordsArePixels property. Note that if the crop region falls partly outside the input image region, black padding will be added as necessary to keep the requested output size.

Configs	Descriptions
imageName	Name of the Image or in the list, List<Image> field to crop.
cropName	Name of the input Data field used for dynamic cropping. May be a BoundingBox or List<Point>.
cropPoints	Static crop region defined as a list of point, List<Point>.
cropBox	Static crop region defined as a bounding box, BoundingBox.
coordsArePixels	Weather the crop region (BoundingBox / List<Point>) are specified in pixels, or fraction of image.
