rotatecrop

The rotatecrop module provides a dialog box providing essential GUI elements for rotating (arbitrary angle) and cropping an image:

Reference

add_panel(panel)

Register a panel to the plot manager

Plot manager’s registration sequence is the following:

  1. add plots

  2. add panels

  3. add tools

add_plot(plot, plot_id=<class 'guiqwt.plot.DefaultPlotID'>)
Register a plot to the plot manager:

  • plot: guiqwt.curve.CurvePlot or guiqwt.image.ImagePlot object

  • plot_id (default id is the plot object’s id: id(plot)): unique ID identifying the plot (any Python object), this ID will be asked by the manager to access this plot later.

Plot manager’s registration sequence is the following:

  1. add plots

  2. add panels

  3. add tools

add_reset_button(layout)

Add the standard reset button

add_separator_tool(toolbar_id=None)

Register a separator tool to the plot manager: the separator tool is just a tool which insert a separator in the plot context menu

add_tool(ToolKlass, *args, **kwargs)
Register a tool to the manager

  • ToolKlass: tool’s class (guiqwt builtin tools are defined in module guiqwt.tools)

  • args: arguments sent to the tool’s class

  • kwargs: keyword arguments sent to the tool’s class

Plot manager’s registration sequence is the following:

  1. add plots

  2. add panels
