IMAQ Configure Buffer VI

NI-IMAQ VI

IMAQ Configure Buffer VI

Installed With: NI Vision Acquisition Software

Configures individual buffers in the buffer list.

You must call IMAQ Configure Buffer for each buffer in the buffer list. Call IMAQ Configure List before calling IMAQ Configure Buffer.

Note  All images in a buffer list must have the same border size and unique names.

Channel specifies the device channel to acquire from. This parameter is valid only for NI PCI/PXI-1409 and NI PCI-1410 devices.

Skipcount is the number of images to skip before the acquisition into the buffer. This parameter is not valid for line scan cameras.

IMAQ Session In identifies the device.

Image In is a reference to an image.

Buffer Number is the index of the buffer in the buffer list you want to acquire.

error in (no error) describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.

code code is the number identifying an error or warning. If status is TRUE, code is a non-zero error code. If status is FALSE, code can be zero or a warning code. Use the error handler VIs to look up the meaning of this code and to display the corresponding error message.

cstr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

IMAQ Session Out has the same value as IMAQ Session In.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

ibool.gif

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

ii32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
