[ros-users] image_pipeline 1.0.1 released

[Adam Leeper]

At line 369  of cameracalibrator.py I have:
    def on_mouse(self, event, x, y, flags, param):
        if event == cv.CV_EVENT_LBUTTONDOWN:
            if self.goodenough:
                if 180 <= y < 280:
                    self.do_calibration()
            if self.calibrated:
                if 280 <= y < 380:
                    self.do_save()
                elif 380 <= y < 480:
                    self.do_upload()
                    rospy.signal_shutdown('Quit')

And at line 402 of cameracalibrator.py I have:
    def buttons(self, display):
        x = self.displaywidth
        self.button(cv.GetSubRect(display, (x,180,100,100)),
"CALIBRATE", self.goodenough)
        self.button(cv.GetSubRect(display, (x,280,100,100)), "SAVE",
self.calibrated)
        self.button(cv.GetSubRect(display, (x,380,100,100)), "COMMIT",
self.calibrated)

If the input images are 320x240, then the whole window is only 240
pixels high, so all those button areas are out of range.

The error is:

OpenCV Error: Incorrect size of input array () in cvGetSubRect, file
/opt/ros/boxturtle/stacks/vision_opencv/opencv2/build/opencv-svn/src/cxcore/cxarray.cpp,
