The path to a Lua script that returns the rotation to apply to the input image, in degrees, clockwise.
The Lua script must define a function named getAngle, which must return the angle. HPE Media Server can rotate images in 90-degree increments, so all other angles are rounded.
The following is an example Lua script that you could use to rotate images based on the angle of a face detected in the image, or text detected in the image. In this example, the angles returned are negative, so the rotation is anticlockwise.
function getAngle(record)
if (record.OCRResultAndImage) then
return -record.OCRResultAndImage.angle
elseif (record.FaceResultAndImage) then
return -record.FaceResultAndImage.face.ellipse.angle
elseif (record.FaceRecognitionResultAndImage) then
return -record.FaceRecognitionResultAndImage.face.ellipse.angle
elseif (record.DemographicsResultAndImage) then
return -record.DemographicsResultAndImage.face.ellipse.angle
elseif (record.FaceStateResultAndImage) then
return -record.FaceStateResultAndImage.face.ellipse.angle
end
return 0
end
