@C1@c@b@_ Intensity Along a Line
Report pixel intensities along a line as 4 xy-plots with the horizontal
axes being the distance, in pixels, along the line and vertical axes as
the RGB intensities and luminosity (or color index in colormap mode)
@b Interaction
The line that defines the path can be manipulated using mouse and/or
keyboard. Use leftmouse and middlemouse to drag the two crosses on
the two ends of the line to change its length and direction. The origin
of the line is marked by a circle on the cross. Other commands are
summarized as follows:
@b KeyBoard
@i Escape
Quit Crop
@i ijkl
Same meaning as in vi. The end these keys apply to is the last one
dragged by the mouse. Shift key can be used to override this behavior.
See Help on Crop for details.
@b menubutton
The following items are available from pop-up menu
@i Help

@b Reporting
Current line length and origin (marked by a circle) are reported in
the file panel as well as the angle the line makes with the horizon-
tal direction.
To get or update the intensity along current line, click the mouse
outside the cross area.
@s@b Note
This one still needs a lot of work.
