IMAQ GetRowCol VI
Owning Palette: Pixel ManipulationInstalled With: NI Vision Development ModuleExtracts a range of pixel values, either a row or column, from an image.
Image is a reference to the source image. |
|||||||
Number is the row or column number to be extracted from the image. |
|||||||
Row / Column (Row) defines Number as a row number when FALSE and as a column number when TRUE. |
|||||||
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 (U16) returns the intensity values for the specified row or column of pixels. Use this output only when Image is an unsigned 16-bit image. |
|||||||
Pixels (U8) returns the intensity values for the specified row or column of pixels. Use this output only when Image is an 8-bit image. |
|||||||
Pixels (I16) returns the intensity values for the specified row or column of pixels. Use this output only when Image is a signed 16-bit image. |
|||||||
Pixels (Float) returns the intensity values for the specified row or column of pixels. Use this output only when Image is a 32-bit floating-point image. |
|||||||
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.
