x1, y1 |
int |
coordinate of start point |
|
x2, y2 |
int |
coordinate of end point |
Output Ports

Description
IPread_line creates a 1D array of values along an x1,y1 to x2,y2 line.
Inputs
-
&src
-
A reference to an ip_Image.
Parameters
-
x1, y1
x2,y2 -
The start and end coordinates of the line along which the data is read.
Outputs
-
buf
-
The buffer of data values, the first npixels of which are valid. The uniform_scalar_field field mapper can make the output array into a field for further downstream processing.
-
npixels
-
The number of pixels read; that is, the number of valid values in buf.
