Description [src]
Find the line Hough transform for in. in must have one band. out has one

of out is the line angle in 0 - 180 degrees, the Y dimension is the
distance of the closest part of that line to the origin in the top-left.
Use width height to set the size of the parameter space image (out),
that is, how accurate the line determination should be.
::: tip “Optional arguments”
* width: gint, horizontal size of parameter space
* height: gint, vertical size of parameter space
