The CameraImage class
Use the function
to retrieve an instance of the
class.
| Attribute |
Access |
Type |
Description |
| name |
R |
string |
the name of the camera image |
| active |
R/W |
0/1 |
active 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() |
0/1 |
resets the filename in simulation
mode (reset simulation cycle) |
The CameraImages class
Use the function
to get the list of all defined
cameras in Scorpion.
| Attribute |
Access |
Type |
Description |
| count |
R |
int |
number of defined cameras in system |
| 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) |
Example 1: Change simulation path according to context def Handle_System_AfterContextChange(Context):
#
# Context = VT_BSTR
#
#set path of simulation images
imgs=GetCameraImages()
imgs.path=imgs.defaultPath+'\\'+Context
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
else:
imgs.get(i).filter='*_%i.bmp' % i
return 0
Example 2: Reset filename for simulation def ResetSimulation(path):
imgs=GetCameraImages()
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):
camImages=GetCameraImages()
for index in range(camImages.count):
if camImages.get(index).name == name:
return index
return -1
