Function Documentation

CanCameraSelect()

cvbbool_t CanCameraSelect

(

IMG

Image

)

This function verifies whether the image supports the CameraSelect interface.

Parameters

[in]

Image

Handle of image object.

Returns

TRUE if the image supports the CameraSelect interface, FALSE otherwise.

Supported platforms:

Win32
Win64
Linux

Examples:

Visual C++ - VC MDI Example (DLL only)

GetCamPort()

cvbres_t GetCamPort	(	IMG	Image,
		cvbval_t &	lPort
	)

Returns the number of the currently selected camera port.

Parameters

[in]	Image	Handle of image object.
[out]	lPort	Current camera port.

Returns

0 : OK
<0 : an error occured

Supported platforms:

Win32
Win64
Linux

GetNumPorts()

cvbres_t GetNumPorts	(	IMG	Image,
		cvbval_t &	lNumPorts
	)

Returns the number of ports of the image or image acquisition device.

Parameters

[in]	Image	Handle of image object.
[out]	lNumPorts	Number of ports.

Returns

0 : OK
<0 : an error occured

Supported platforms:

Win32
Win64
Linux

SetCamPort()

cvbres_t SetCamPort	(	IMG	Image,
		cvbval_t	lPort,
		cvbval_t	lImgToWait
	)

Sets the current camera port.

Depending on the camera timing mode and the acquisition device, it is important to set the lImgToWait to a value that allows the acquisition device time to synchronise. If images are not synchronised after switching increase this number by 1 or 2 frames.

Parameters

[in]	Image	Handle of image object.
[in]	lPort	Port to be set active.
[in]	lImgToWait	Specifies the number of vertical blanks to wait after switching in order to give the PLL enough time to prepare for the new signal.

Returns

0 : OK
<0 : an error occured
