Setting the region of interest for acquisition when using a Firewire camera

[Steverino]

I would like to programmatically set region of interest for acquisition when using a Firewire camera. I am programming in VB, using IMAQ Vision 7.1, and IEEE-1394 driver v2.0.0.

I know that I can set the region using MAX, but I want to do it programmatically, in case the user does something bad!  I have set other features (e.g., Mode, Format, etc.) programmatically, but can't figger this one out.

Can this be done, and if so, how?

Thanks!

Hi Steverino,

For the acquisition window, I believe you will want to use these properties:

CWIMAQ.AcquisitionWindowHeight

CWIMAQ.AcquisitionWindowWidth

CWIMAQ.AcquisitionWindowLeft

CWIMAQ.AcquisitionWindowTop

These should all be outlined in more detail in the IMAQ Vision for Visual Basic Reference Help, which should be installed with IMAQ Vision.

Hope this helps!

Robert
