IMAQ ColorImageToArray VI
Owning Palette: Color UtilitiesInstalled With: NI Vision Development ModuleExtracts the pixels from a color image or from part of a color image into a 2D array. This VI returns the values as a 2D array of either unsigned 32-bit integers or clusters of four unsigned 16-bit integers, depending on the bit depth of Image. You can convert a 2D array of unsigned 32-bit integers into a 2D array of clusters coding the three color values as either (R, G, B), (H, S, L), (H, S, V), or (H, S, I) using the IMAQ IntegerToColorValue VI.

Optional Rectangle defines a four-element array that contains the left, top, right, and bottom coordinates of the region to process. The VI applies the operation to the entire image if Optional Rectangle is empty or not connected. |

Image is a reference to the source image. |

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.

Image Pixels (U32) returns the pixel values as a 2D array of unsigned 32-bit integers. |

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.

Image Pixels (U64) returns the pixel values as a cluster of four unsigned 16-bit integers.
