Crop Area
• With the crop node a ‘crop area‘  photo can be
specified by the x/y-size and the origin of the crop box in
relation to the original image.
By selecting a projection aspect ratio (e.g. 1.66) in the
‘output format’ node the maximum appropriate ‘crop area’
settings are adjusted automatically and, if necessary,
the image is auto scaled to fit into the chosen ‘output
format ’.
By default the x-size of the crop box is set to
maximum input image width and the image height is
selected according to the aspect ratio.
Crop box handling with the aspect locked:
CTRL + drag the center -> move the crop box.
ALT + drag the border -> vary the size fixed to its center.
Drag a corner -> vary the size fixed
to the opposite corner.
Drag a side -> vary the size fixed
to the opposite side.
