The "Photoshifter" is a special tool for correctly correcting the perspective of crooked lines and objects photographed at an angle. For example, facades or paintings are corrected so that all proportions are reproduced absolutely truthfully and can then be measured in FixFoto.
Is installed with FixFoto for testing! Can be found in FixFoto under "Reshape" and the penultimate item there.
