could you integrate code for image pan and also image zoom in and out from center, currently its zooming form top left corner. I would be great If you could integrate the code and update ASAP

OS: mac os
PyQt version: 5
Error: Segmentation fault: 11

Solution: open labelImg.py, go to line 175, comment this line.

    self.filedock.setWidget(fileListContainer)

    self.zoomWidget = ZoomWidget()
    # self.colorDialog = ColorDialog(parent=self)

    self.canvas = Canvas()

I also encountered the same problem

I tried to solve him in a bad way

filepath:  roLabelImg-master\libs\canvas.py    line: 159

if Qt.LeftButton & ev.buttons():
            self.MouseMove = ev.pos() - self.preMousePosition
            self.preMousePosition = ev.pos() 
            self.prevPoint = self.pos() + self.MouseMove
            self.move(self.prevPoint)

filepath:  roLabelImg-master\libs\canvas.py    line: 225

self.preMousePosition = ev.pos()

If you have any good plan, please contact me, thank you very much
