profile

Name

profile - Calculate pixel values along a line

 profile [-o outfile] [-x <x> -y <y>] [-d dir]
         [-ip <val>] [-ex <x> -ey <y>] [-s <step>] <image>

profile calculates the pixel values along a line starting at (x,y) in the direction dir (in radians).

An alternative is to specify the startpoint (x,y) and the endpoint (ex,ey) of the profile.

The profile has one sample per step pixel, and an interpolation of degree ip is used (only degree 1 is implemented).

The result is written to stdout or to a file specified by the -o switch.
