Demos and Examples
Sapera comes with several generic demos and examples. In this section, we provide a description of
each of them.
Certain board driver installations provide other demos and examples that demonstrate the specific
usages and capabilities of the board. Refer to a specific board user’s manual for further details.
Acquiring with GrabDemo
The GrabDemo allows you to grab and display a live image within a host buffer. It can
accommodate any Sapera-compatible board with any camera. This demo is a good starting-point
when verifying that your camera and frame grabber are properly installed.
The following dialog box appears when starting GrabDemo:
You must select the Acquisition Server and the Acquisition Device. The first one corresponds to
the board you want to grab from; the second one represents the acquisition device on this board
(some boards may have more than one).
You must then select a camera file (CAM File) compatible with your camera from the list of
available files. A video-input-conditioning file (VIC File) is also required. This VIC file is specific
to the frame grabber you select. You can use the Generate Default option to create a default VIC
file since they are not provided with Sapera. CamExpert may be used to generate specialized VIC
files (e.g., external trigger, cropping window, etc).
Note: No frame-grabber was found within your system if this dialog box does not appear. In such a
case, verify that the device driver corresponding to your frame-grabber was correctly installed. The
