A Stack plugin is a module that will be automatically added to the PyMca stack windows
in order to perform user defined operations on the data stack.
These plugins will be compatible with any stack window that provides the functions:
#data related
getStackDataObject
getStackData
getStackInfo
setStack
#images related
addImage
removeImage
replaceImage
#mask related
setSelectionMask
getSelectionMask
#displayed curves
getActiveCurve
getGraphXLimits
getGraphYLimits
#information method
stackUpdated
selectionMaskUpdated
