Set Properties for Matrox Acquisition

13-5

You can then preview and acquire images, as described in “Acquire Images from

Matrox Frame Grabbers” on page 13-6.

Note: If you need to change any properties after you preview your image, you must

change them in the DCF file, and then create a new object to pick up the changes.

Configuring Hardware Triggering

If your DCF file is configured for hardware triggering, then you must provide the trigger

to acquire images. To do that, call the snapshot function as you normally would,

as described in “Acquire One Image Frame from a Matrox Frame Grabber” on page

13-7, and then perform the hardware trigger to acquire the frame.

Note that when you call the snapshot function with hardware triggering set, it will not

timeout as it normally would. Therefore, the MATLAB command-line will be blocked

until you perform the hardware trigger.
