Example Python code to read frames from Prosilica camera using Lima

gistfile1.py

from Lima import Core, Prosilica
from Qub.CTools import pixmaptools

# initialize Lima and connect to camera
prosilica = Prosilica.Camera("192.168.1.2")
interface = Prosilica.Interface(prosilica)
control = Core.CtControl(interface)
video = control.video()
video.setExposure(1.0/25.0)

# start frames acquisition
video.startLive()

# the easiest is to periodically call this function
# to get the latest frame (like, every 40 milliseconds),
# passing the 'video' Lima object as argument
def get_last_frame(video):
  image = video.getLastImage()
  raw_buffer = image.buffer()
  
  # by default, images returned by the Prosilica
  # opened with Lima are Bayer format, 16 bits ;
  # it has to be converted to RGB in a QImage for
  # Qt to be able to display it ;
  # we use Qub for this task
  scaling = pixmaptools.LUT.Scaling()
  scaling.autoscale_plus_minus_sigma(raw_buffer,
                                     image.width(), image.height(),
                                     pixmaptools.LUT.Scaling.BAYER_RG16, 3)
  validFlag,qimage = pixmaptools.LUT.raw_video_2_image(raw_buffer,
                                                       image.width(),
                                                       image.height(),
                                                       pixmaptools.LUT.Scaling.BAYER_RG16,
                                                       scaling)

  # other formats than Bayer 16 can be selected:
  # using "video.setMode", eg. video.setMode(Core.BAYER_RG16)
  # this has to be set prior to starting acquisition.
