Release Notes


The CameraImage class

Use the function

  • GetCameraImage(name)

to retrieve an instance of the class.

Attribute Access Type Description
name R string the name of the camera image
index R int index of camera image (zero index, 0..n-1)
active R/W bool active state
intermediate R/W bool intermediate state
autoClear R/W bool auto clear state
camera R/W string name of connected camera
cameraNo R/W int camerano of connected camera (zero index, 0..n-1)
rotation R/W 0/1 0=None, 1=90, 2=180, 3=-90, 4=VFlip, 5=HFlip
simulation R/W 0/1 current state of individual simulation flag
path R/W string image path when simulation
filter R/W string image filter when simulation (ex : *_0.bmp, *_1.jpg, *.* )
fileRotation R/W int rotation when in simulation, values see above for values
filename R string filename of current image in simulation mode
grabDuration R int duration between grab command and received image of last image


Method Returns Description
resetFilename() bool resets the filename in simulation mode (reset simulation cycle)

The CameraImages class

Use the function

  • GetCameraImages()

to get the list of all defined cameras in Scorpion.

Attribute Access Type Description
count R int number of defined cameras in system
names R tuple all names as tuple
simulation R/W 0/1 state of simulation, an active simulation state overrides the individual settings and sets all cameras in simulation mode
path W string sets path for all camera images.
Note that this is write only since each CameraImage may have individual paths. It is recommended to read the path of camera 1 if you want to set all paths equal
defaultPath R string default path when adding camera images, equals the profile path

Method Returns Description
get(index) CameraImage returns a CameraImage instanse if valid index
getCameraImage(name) CameraImage returns a CameraImage instanse if valid name
resetFilenames() 0/1 resets filenames for all cameraImages in simulation mode (resets simulation cycle)
configure(code=0) bool launches configuration dialogs due to code parameter
  code=0: complete images configuration dialog
  code=1: folder dialog
  code=2: sequence dialog
  code=3: filter dialog
load(filename)  bool load configuration from file
save(filename) bool save configuration to file

Example 1: Change simulation path according to context

def Handle_System_AfterContextChange(Context):
  # Context = VT_BSTR

  #set path of simulation images

  for i in range(imgs.count):
    if Context=='V1':                              #the simulation images are JPEG's for product V1, the other products are bmps
      imgs.get(i).filter='*_%i.jpg' % i
      imgs.get(i).filter='*_%i.bmp' % i

  return 0

Example 2: Reset filename for simulation

def ResetSimulation(path):
  imgs.resetFilenames()           #resets simulation filename cycle

Example 3: Change the cameraNo by cameraName

def ChangeCamera(image, cameraNo):
  camImg=GetCameraImage(image)      #get camera image by name
  camImg.cameraNo=cameraNo             #set the attached camera

Example 4: ImageNo by ImageName

def GetImageNoByImageName(name):
  for index in range(camImages.count):
    if camImages.get(index).name == name:
      return index
  return -1

Example 5: ImageNo by ImageName

def GetImageNoByImageName(name):
  return GetCameraImage(name).index    #implemented in Scorpion

Example 6: Load image configuration

def LoadImageConfig():
  import os
  print fname,GetCameraImages().load(fname)
