Radial Profile- Non Circular Shapes

Wei Ju Lin
To whom it may concern,

We are looking to utilize the functions of  the radial profile plugin, but would like to be able to create a custom boundary (other than a circle).

?

Hi Wei Ju,

in case you don't need the center and you can live with a shape that is
not closed, you can create a splined segmented line (select 'Segmented
Line' with right-click on the line tool, then double click for options).
Then use Edit>Selection>Straighten to convert to a rectangular image.
You can get a profile with 'Select all' and 'Plot Profile' (Alt-key for
a vertical profile, corresponding to a radial profile of the original).

For the 'radial' direction, 'Straighten' is based on the direction
perpendicular to the line. So, if you don't have a circle it is somewhat
different to a radial profile, which would use the direction to a fixed
center.

Unfortunately, 'Straighten' currently does not work with closed lines
(splined polygons).
