Setting all keystone values to 0 will place all four corners of the image at the four corners of the projector output.
The keystone values can also be used to create interesting skewing effects.
For the picture merging are important both the KeyStone X-ratio and KeyStoneY-ratio channels for correction of
the image distortion caused by placing projectors at different distances from the final image.
If the channel Global effect 1 - Parameter 3 is set to the range of 171-180, the aspect ratio of an actual image is
displayed in the image. The feature is activated when the Picture Merging is active only.
16.2 Layer keystone parameters
By the global keystone parameters stated above you can control each of the four corners of the graphics output
individually to reshape your image to a form that is projected correctly.
By the layer keystone parameters you can control all four corners of the image at the same time. With these
parameters you can create the same skewing and shape effects like with the global keystone parameters but on
each gobo layer.
Major use of these effects is in a situation where the gobo mask is applied on a layer and you need to adjust a mask
shape onto some object on the scene. More important is adjusting of the inner part of the image on the layer than
the outer shape of the graphics output.
Characteristic case is a composition of 2 layers: the layer 1, where is applied a picture of the landscape and the
layer 2, where is a gobo mask selected (see picture below).
