Extract a line of pixels from a color image.
This node 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 Integer To Color Value.gvi node.
Reference to the source image.
Numeric array that specifies the start x, start y, end x, and end y coordinates of the two end points of the line to extract.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Reference to the source image.
Numeric indicator that returns the pixel values as a 1D array of unsigned 32-bit integer indicators.
Numeric indicator that returns the pixel values as clusters of four unsigned 16-bit integers.
Value of the red plane.
Value of the green plane.
Value of the blue plane.
Value of the alpha plane.
