IMAQ GetColorPixelLine VI
Owning Palette: Color UtilitiesInstalled With: NI Vision Development ModuleExtracts a line of pixels from a color image. This VI returns an 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 an array of 32-bit integers into an 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.

Line Coordinates is an array specifying the start x, start y, end x, and end y coordinates of the two end points of the line to extract.

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.

Pixels Line (U32) returns the pixel values as a 1D array of unsigned 32-bit integer indicators. |

 |
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.

Pixels Line (U64) returns the pixel values as clusters of four unsigned 16-bit integers.
