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.
Plugins can be automatically installed provided they are in the appropriate place:
- In the user home directory (POSIX systems): *${HOME}/.pymca/plugins*
or *${HOME}/PyMca/plugins* (older PyMca installation)
- In *"My Documents\\\\PyMca\\\\plugins"* (Windows)
It has to inherit the :class:`StackPluginBase` class and implement the following methods:
- :meth:`StackPluginBase.getMethods`
- :meth:`StackPluginBase.getMethodToolTip` (optional but convenient)
- :meth:`StackPluginBase.getMethodPixmap` (optional)
- :meth:`StackPluginBase.applyMethod`
and modify the static module variable :const:`MENU_TEXT` and the static module function
:func:`getStackPluginInstance` according to the defined plugin.
The plugin class has access to following inherited methods:
- :meth:`StackPluginBase.addImage`
- :meth:`StackPluginBase.getActiveCurve`
- :meth:`StackPluginBase.getGraphXLabel`
- :meth:`StackPluginBase.getGraphXLimits`
- :meth:`StackPluginBase.getGraphYLabel`
- :meth:`StackPluginBase.getGraphYLimits`
- :meth:`StackPluginBase.getStackData`
- :meth:`StackPluginBase.getStackDataObject`
- :meth:`StackPluginBase.getStackDataObjectList`
- :meth:`StackPluginBase.getStackInfo`
- :meth:`StackPluginBase.getStackOriginalCurve`
- :meth:`StackPluginBase.getStackOriginalImage`
- :meth:`StackPluginBase.getStackROIImagesAndNames`
- :meth:`StackPluginBase.getStackSelectionMask`
- :meth:`StackPluginBase.isStackFinite`
- :meth:`StackPluginBase.removeImage`
- :meth:`StackPluginBase.replaceImage`
- :meth:`StackPluginBase.setStack`
- :meth:`StackPluginBase.setStackSelectionMask`
- :meth:`StackPluginBase.stackClosed`
These plugins will be compatible with any stack window that provides the following methods:
#data related
- :meth:`getStackDataObject`
- :meth:`getStackData`
- :meth:`getStackInfo`
- :meth:`setStack`
- :meth:`getStackROIImagesAndNames`
- :meth:`isStackFinite`
- :meth:`getStackOriginalCurve`
- :meth:`getStackOriginalImage`
#mask related
- :meth:`setStackSelectionMask`
- :meth:`getStackSelectionMask`
#displayed curves
- :meth:`getActiveCurve`
- :meth:`getGraphXLimits`
- :meth:`getGraphYLimits`
- :meth:`getGraphXLabel`
- :meth:`getGraphYLabel`
#images
- :meth:`addImage`
- :meth:`removeImage`
- :meth:`replaceImage`
#information method
- :meth:`stackUpdated`
- :meth:`selectionMaskUpdated`
- :meth:`stackClosed`
