To evaluate and correct inversion automatically you can use ImgAutoInvert else you can evaluate inversion and then invert the image using ImgInvert.

IsInverted:=ImgEvaluateInversion(_CurrentImage);

// Log a message 

if IsInverted

then ApplicationLog('Image is inverted !')

else ApplicationLog('Image is NOT inverted !')
