int
|
coordinate of end point

Description
IPread_line creates a 1D array of values along an x1,y1 to x2,y2 line.
Input
&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.
Output Port
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
