Grab Demo Overview
The Grab Demo program demonstrates the basic acquisition functions included in the Sapera
library (Sapera LT 8.7). The program either allows you to acquire images, in continuous (grab) or
in one-time (snap) mode, while adjusting the acquisition parameters. The program code may be
extracted for use within your own application.
Using the Grab Demo
To open the Grab Demo program
•
In Sapera Explorer, on the left pane select Demos, then double-click Grab Demo (see Figure
Alternately, from the Start menu, select Teledyne DALSA Sapera LT > + Demos
(Executables), which will open the folder where GrabDemo.exe is located.
Acquisition Configuration Window
When using frame grabbers, the demo program first displays the Acquisition Configuration window,
where you can select from the available Sapera acquisition servers and input devices present on
the selected server.
•
From the Acquisition Server list, select and installed Sapera acquisition server (installed
Teledyne DALSA acquisition hardware using Sapera drivers).
•
From the Acquisition Device list, select an available input device on the selected driver.
•
Click Browse to select the required camera configuration file for the connected camera. Sapera
camera files contain timing parameters and video conditioning parameters. The default folder
for camera configuration files is the same used by the CamExpert utility to save user generated
or modified camera files.
Use CamExpert program to generate the camera configuration file based on timing and control
parameters entered. The CamExpert live acquisition window allows immediate verification of
those parameters. CamExpert reads both Sapera *.cca and *.cvi for backward compatibility
with the original Sapera camera files.
Grab Demo Main Window
The Grab Demo program provides basic acquisition controls for the selected frame grabber. The
loaded camera file (.ccf) defines the frame buffer defaults.
Refer to the Sapera LT Getting Started Manual for Frame Grabbers (OC-SAPM-INTRO), chapter
Demos and Examples, for more information on the Grab Demo and other programs provided with
Sapera LT.
