In this example, we create a contextual menu for arbitrary lines in map seismic outlines. The script behind this contextual menu converts the coordinates of that line to the INLINE-XLINE coordinates of the other outline layer in the same window

The text of the script is:

window = layer.getViewerWindow()

allLayers = window.getAllLayers()

for currentLayer in allLayers:

  if currentLayer != layer:

  otherLayer = currentLayer

  break

otherIJToXY = otherLayer.getIJToXY()

newPolyline=TraverseData('MyData', 'INLINE', 'XLINE')

allPoints = polyline.getPoints()

for currentPoint in allPoints:

 x = currentPoint[0]

 y = currentPoint[1]

 trans = otherIJToXY.invCoordTrans(x, y)

 inline = trans[0]

 xline = trans[1]

 newPolyline.addPoint(inline, xline)

writer=TraverseDataWriter(newPolyline)

saver = TraverseDataSaver()

saver.saveInBackground(newPolyline, None)

Place this "ConvertAndSave.py" script in the Contextual_Map_Outline_Polyline directory of your Python scripts directory

Press the button "Refresh from Disk" in your Python options. Your script should appear.

And it should be available as a contextual menu of your polyline

Select the "ConvertAndSave.py" menu item to launch this script. After performing the conversion, this script prompts the user for a location on disk where to save the converted arbitrary line. Use the "Load Arbitrary Line" menu item to load this arbitrary line onto the other layer.
