IMAQ Bayer To RGB

Image Src is a reference to the Bayer-encoded image. This image can be an 8-, 10-, 12-, 14-, or 16-bit image. 8-bit images can only be decoded to RGB 32-bit. All other images can be decoded to RGB 32-bit or RGB 64-bit.

Image Dst is a reference to the destination image.

Bayer Parameters specifies the Bayer settings to use to create the image.

Pattern specifies the variation of the Bayer encoding pattern to use.

Algorithm specifies the algorithm to use to create the image. Because the bilinear algorithm is faster, it is recommended to try the bilinear algorithm before the VNG algorithm. If the image contains many edges, or if the quality of edges in the image is important use the VNG algorithm.

Bilinear (0)	(Default) Uses bilinear interpolation to compute pixel values.
VNG (1)	Uses variable number of gradients interpolation to compute pixel values.

Red Gain is the gain to be applied to the red pixels in a Bayer-encoded image. The valid range for this parameter is 0 to 3.999.

Green Gain is the gain to be applied to the green pixels in a Bayer-encoded image. The valid range for this parameter is 0 to 3.999.

Blue Gain is the gain to be applied to the blue pixels in a Bayer-encoded image. The valid range for this parameter is 0 to 3.999.

error in (no error) describes the error status 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 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.

Image Dst Out is a reference to the destination image. If Image Dst is connected, Image Dst Out is the same as Image Dst. Otherwise, Image Dst Out refers to the image referenced by Image Src.

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.

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