Display polygon labels in the image itself.

[krishvishal]

Right now to know the label assigned to a polygon we have to check by de-selecting that particular instance of the label. This is a trail and error method and takes considerable amount of to recheck which label a particular polygon has been assigned. Is there a way to display label names around each polygon?

Currently, this feature is not supported.

Taking 10x more time to individually click and check category name.

This should be there from the very beginning.

What @yuhorun suggests sounds good. @yuhorun you could suggest your suggestion @wkentaro in a branch.

• Go to Canvas.py file
• find out the def paintEvent(self, event):
• add below code in just before for loop and inside loop
  p.setPen(QtGui.QColor(168, 34, 3))
p.setFont(QtGui.QFont('Decorative', 20))
Shape.scale = self.scale
for shape in self.shapes:
p.drawText(shape.points[0].x(),shape.points[0].y(), shape.label)
• You will see the below result

Thanks, @ratnadeepkedar. I've modified your answer a little:

            pixel = 1.0 / self.scale
            p.setFont(QtGui.QFont('Decorative', int(12 * pixel)))
            for shape in self.shapes:
                x, y = (min(shape.points[0].x(), shape.points[1].x()), shape.points[0].y() - pixel * 6) \
                    if shape.shape_type == "rectangle" else (shape.points[0].x(), shape.points[0].y() - pixel * 6)
                color = shape.line_color
                p.setPen(color.darker(200))
                p.drawText(x + pixel * 2, y + pixel * 2, shape.label)
                p.setPen(color)
                p.drawText(x + pixel, y + pixel, shape.label)
                p.setPen(color.lighter(200))
                p.drawText(x, y, shape.label)
