Win32 Systems (Win98, Me, NT, 2000 and XP)

This sample shows you how to use the Offset and Gain features of the PXR800. In this sample we use Windows scroll bars to let you control the offset and gain, but in a program that you write, you might use different types of controls. Nonetheless, the use of the offset and gain functions is the same regardless of the method used for control.

The functions used in this sample are:

GetFineGain()
SetFineGain()
GetOffset()
SetOffset()

In this sample you will learn how to do the following:

1. Create a simple control window.
2. Create a video display window.
3. Initialize the PXR frame grabber.
4. Grab frames and display them in realtime in the video display window.
5. Change and retrieve (set and get) gain and offset values.

The Visual Basic support for the PXR800 requires the following header files and libraries.

1. PXR800API.BAS
2. PXR800.BAS
3. PXRFRAME.BAS
4. IMAGINFO.BAS
5. PXR800_DISPLAY.BAS
6. PXR800.DLL
7. PXRFRAME.DLL
8. PXR800_DISPLAY.DLL
