PERSPECTIVE_TRANSFORM

Configs	Descriptions
inputNames	A list of names of the input fields to process. May be points, bounding boxes, images, or lists of these. If input names are not set, the fields of these types will be inferred automatically.
outputNames	A list of names of the output field. If not set, the output has the same name as the input field.
sourcePointsName	List of 4 source points: top left, top right, bottom left, bottom right.
targetPointsName	List of 4 target points: top left, top right, bottom left, bottom right.
referenceImage	When a referenceImage is provided, the transform will be adjusted to ensure the entire transformed image fits into the output image (up to 4096x4096). Can also reference a list of images, in which case, only the first image is used as the reference.The adjustment is applied to all inputs of the step.
referenceWidth	When a reference width and height are provided, the transform will be adjusted to make sure the entire area fits into the output image (up to 4096x4096). The adjustment is applied to all inputs of the step.
referenceHeight	When a reference width and height are provided, the transform will be adjusted to make sure the entire area fits into the output image (up to 4096x4096). The adjustment is applied to all inputs of the step.
sourcePoints	Takes exactly 4 source points: top left, top right, bottom left, bottom right.
targetPoints	Takes exactly 4 target points: top left, top right, bottom left, bottom right.
keepOtherFields	If true, other data key and values from the previous step are kept and passed on to the next step as well. Default value is set to true.
