about sif.py and others in guiqwt

Hi People:
Ihave two questions:
1) sift.py works with other files (tools.py, plot.py, etc.), where I work with
the context menu to add or remove options
2) the tool annotatedSegmentTool shows distance in pixels, but I'm looking
for where you store this result (numeric variable) to make a
conversion from pixels
in a real size of a photograph loaded

Thanks in advance

I do not understand this question. What do you want to do?

I haven't tried myself, but I guess what you need is
AnnotatedSegment.get_tr_length()
or get_text() or get_infos()
See:

Carlos:

Thanks for reply.
A context menu (or contextual menu) appears with rigth click mouse (or
middle click) and offers a set of choices available. How can I add or
delete options
in this menu?
best regards

AFAIK, all the options in the context menu of guiqwt plots are associated to
"tools"
So you have to add/remove tool. Have a look on the guiqwt docs and in the
tools.py file of guiqwt source code.

Note, you can create your own tools. I do it in my extension of guiqwt for
taurus:
http://tango-cs.svn.sourceforge.net/viewvc/tango-
cs/gui/taurus/trunk/lib/taurus/qt/qtgui/extra_guiqwt/tools.py?revision=17889&view=markup

Finally, the menu itself is a PyQt4.Qt.QMenu, so if you want to go low-level,
you can get the menu object and add/remove QActions (but that should be the
last option)

You want to configure the Anotation tool's transform_matrix which is
located in the annotationparam property of the Annotated item,
You set the 'create_shape' function to your own for the tool you want
in your overridden "register_tools" function, 'create_shape' is called
when the tool is created, so it gives you a chance to set things up
the way you want.

def create_seg_shape(self):
print 'create_seg_shape:'
ap = AnnotationParam()
ap.title = '%s %d' % (SPATIAL_TYPE_PREFIX[SEG], self.segNum)
ap.transform_matrix = [[ 5.0, 0.0, 0.0],[ 0.0, 10.0, 0.0],
[ 0.0, 0.0, 1.0]]
ap.format = '%5.2f um'
return AnnotatedSegment(0, 0, 1, 1, annotationparam = ap), 0,
2

def register_tools(self):
ast = AnnotatedSegmentTool
ast.create_shape = self.create_seg_shape
aa = self.add_tool(ast, setup_shape_cb=self.setupsegment,
handle_final_shape_cb=self.newsegment)
aa.TITLE = _("Seg 0")
