ImgEvaluateOrientation

Prototype

intAngle:=ImgEvaluateOrientation(intImageHandle)

Description

Evaluates orientation angle for the image.

Parameters

intImageHandle: integer value corresponding to the image handle.

Returned value

Integer value with calculated orientation angle (clockwise): can be 90, 180 or 270

Notes

To evaluate and correct orientation automatically you can use ImgAutoOrient else you can evaluate angle and the rotate the image using ImgRotate. Please note that returned value is the orientation angle and not the angle to be rotate to get well oriented image, so, as example, if the result is 90 then to get correct oriented image you have to make a 270° rotation.

Example

// Find orientation angle

Angle:=ImgEvaluateOrientation(_CurrentImage);

// Log a message 

ApplicationLog('Orientation angle is: '+ IntToStr(Angle) +'°.');
