@C1@c@b@_ Crop
To eliminate parts of an image that are outside the region of interest
defined by a rubber band, which can be larger than current window
or screen size.
@b Interaction
@b menubutton
The following items are available from pop-up menu
@i Doit
crop with current region
@i BdColor:
change the color of the rubber band.
@i Frame1
enlarge the rubber band by 1 pixel one all sides.
@i FrameN
enlarge the rubber band by N pixels one all sides.
@i Auto

@b middlemouse & leftmouse
Use left and middle mouse to drag the small crosses on the rubber
band and thus both the size and location of the rubber band can
be changed this way. If control key is down, dragging the mouse
moves the rubber band rigidly.
@b keyboard
@f Escape
Same as Cancel
@f [1-9]
set the step size for ijkl and xXyY commands.
@f ijkl OR arrow keys
Same meaning as in vi(1). The corner these keys apply to is
the one closest to mouse. Shift key can be used to override
this default behavior: if leftshift is down, ijkl moves the lower-left
corner and if rightshift is down, ijkl moves top-right corner
regardless which corner is last dragged by the mouse.
@f xXyY
adjust the width/height of the rubber band
@b Panning in crop
Crop region larger than window/screen can be achieved by using
the pan buttons in the edit panel.
@b Reporting
Current bounding area size and origin (lower-left corner) are
reported in the file panel whenever changes to them occur. The step
size for ijkl movement is also reported.
@b@C1 Warning
Bit will perform framebuffer reads if there are text and sgfs present
(rendered in Deferred mode).
