int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

Type:

pyqtSignal(*types, name

Type:

str = …, revision

set_points(points)

Set a point to a new ID

Parameters:

• pos (QPointF) - position of the point on the screen

update_pix()

update_points()

Gui.Slide_Viewer

openalea.image.gui.slide_viewer

This module contains a widget that allows viewing of image stacks. It should thus be called slice_viewer, not slide_viewer.

This module provide a simple viewer to display 3D stacks

class openalea.image.gui.slide_viewer.SlideViewer(parent=None)

Display each image in a stack using a slider

A pure QWidget (instead of QMainWindow) is also available, see openalea.image.gui.slide_viewer_widget.
