IMAQ GetColorPixelValue VI
Owning Palette: Color UtilitiesInstalled With: NI Vision Development ModuleReads the pixel values from a color image. This VI returns the pixel value as either an unsigned 32-bit integer or a cluster of four unsigned 16-bit integers, depending on the bit depth of Image. You can convert the 32-bit integer into a cluster containing three elements possessing either (R, G, B), (H, S, L), (H, S, V), or (H, S, I) using the IMAQ IntegerToColorValue VI.

Image is a reference to the source image. |

 |
X Coordinate is the horizontal coordinate of the pixel. |
||||||||
|
Y Coordinate is the vertical coordinate of the pixel. |

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.

Pixel Value (U32) returns the pixel value as an unsigned 32-bit integer. |
||||||||
 |
Pixel Value (U64) returns the pixel value as a cluster of four unsigned 16-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.
