/* DOCUMENT rezone, filename
-or- rezone
Invoke the mouse-driven rezoner. Input is taken from variables
rt, zt, and ireg in the file FILENAME (which is prompted for if
omitted). Output is written to a different file as rt, zt, and
ireg. The output file also contains copies rez_rt, rez_zt, and
rez_ireg in case the mesh under a different name is desirable,
as well as rez_rt0, rez_zt0, and rez_ireg0, which are the original
mesh.
If you click on [Escape], you may continue rezoning where you left
off by typing rezone with no arguments.
When you are finished, click [OK] to write the output file.
Use [Zoom or Pan] and [Set Styles] to change the plot limits or
line colors and styles. The [Zoom or Pan] screen has buttons which
"warp" you to each bowtied or chevroned "problem" zone, as well as
a button to toggle between rectangular and polar coordinates.
Click [Drag Points] to drag points one at a time with the mouse.
Click [Adjust Line] to smooth the points on logical line segments.
You first click on the endpoints P and Q, then click a button to
smooth or equal space the poionts between P and Q, or drag any
point between P and Q to establish equal ratio zones ("ER" operation).
Click [Adjust Region] to smooth the points in logically rectangular
regions. You first click on the opposite corners P and R of the
rectangle PQRS, then click a button to smooth the interior points,
or click on a point on one of the four edges to transfer the spacing
on that edge throughout the region PQRS ("EQ" operation).
The [Undo] (or [Redo]) button removes the effect of the most
recent drag points, adjust line, or adjust region operation.
Hints:
(0) After [Escape], the current mesh is in the variables
rez_zt, rez_rt, and rez_ireg. You can change these
variables "by hand" before restarting rezone to make
algebraic adjustments.
(1) Switch to polar coordinates during an [Adjust Line] or
[Adjust Region] in order to get points to lie along a
circular arc. If your center point is not (0,0), you
will need to [Escape] and subtract your center point
from the rez_zt and rez_rt variables yourself, then
[Escape] a second time to restore the proper coordinates
before you write the output file.
(2) You can select a center point as the second point during
[Adjust Line] or [Adjust Region]. When you do this, the
K (or L) value of this second point will be the same as
that of the first point -- otherwise there is no way to
distinguish among all of the logical points at the center.
In an [Adjust Region], the center point will be labeled
Q instead of R as usual, and you will need to choose a
third point (S) to complete the rectangle PQRS.
(3) If you set the variable rez_color=1 before you include
rezone.i, you will get K lines and L lines drawn in different
colors instead of the default (which is K lines dashdot and
L lines solid).
(4) If you have a color monitor, you can set rez_regs before
invoking rezone in order to highlight a list of regions.
The ALL keyword will be passed to the nbow function, which will
not be called if the QUIET keyword is non-nil and non-zero. By
default, a short summary of bowtied and chevroned zones is printed.
If you need help on how to use one of the screens, try getting
help on the appropriate on of these SEE ALSO topics, e.g.-
help, rez_style
to get help on the [Set Styles] screen.

Click on [Smooth] to smooth the points along PQ.
Click on [Equal Space] to make the points along PQ equally spaced.
This forces PQ to be a straight line.
Drag any point between P and Q to get equal ratio spacing of all
the points between P and Q. This also forces PQ to be a straight
line; if PQ is initially curved, you may want to click on

Hint:
You can select a center point as the second point during

/* DOCUMENT rez_radj
Adjust the points in a logical rectangle PQRS:
Click on [Set P] or [Set R] to set the endpoints of the segment.
When P and R have been set, click [OK]; this button will
read [Cancel] if P and R have the same K or the same L index.
Click on a point on any edge of PQRS (but not one of the corners)
to copy the spacings on that edge throughout the entire region.
All of the lines of the same type (K-line or L-line) as the edge
you clicked on will become straight lines.
Click on [Smooth] to smooth the points interior to PQRS.
Click on [Smooth 4] to perform the smooth operation four times.
Click on the [Undo] button to undo the previous adjustment; you can
undo up to 10 previous adjustments by successive [Undo] clicks.
When you are finished adjusting regions, click on [OK].
Click on [Zoom or Pan] to change the plot limits (see rez_zoom).
Click on [Set Styles] to change the line styles or colors (see
rez_style).
Hint:
You can select a center point as the second point during
rez_radj. When you do this, the K (or L) value of this second
point will be the same as that of the first point --
otherwise there is no way to distinguish among all of the
logical points at the center. The center point will be labeled
Q instead of R as usual, and you will need to choose a third
point (S) to complete the rectangle PQRS.

/* DOCUMENT rez_zoom
Change limits after setting rez_mesh.
There are two modes of operation:
(1) P-mode:
Click on a point to magnify or demagnify about that point.
Drag the point to move it to a different position in the
viewport. The left button zooms in (magnifies by 1.5), the
right button zooms out (demagnifies by 1.5), and the middle
button pans (no magnification change). If you click just
below or just above the tick marks, only the x coordinate
is changed; clicking just to the left or just to the right
of the viewport changes only the y coordinate.
(2) R-mode:
Left drag out a rectangle to set the limits to that rectangle.
Right drag out a rectangle to cram the entire current viewport
into that rectangle (an analog to zooming out).
Middle drag to pan as in P-mode (the rubber band rectangle is
meaningless in this case).
Click the [R-mode] (or [P-mode]) button to change modes.
Click the [OK] button when you are satisfied with the limits.
Click the [Undo] button to remove the effect of the previous
zoom-click. Up to 100 successive undo operations are allowed.
Click the [Polar] button to toggle polar coordinates. The
vertical axis will be theta, and the horizontal axis radius.
The polar coordinate origin will be at (zt,rt) = (0,0).
Click the [Next], [Prev], or [First] buttons to focus in on
zones which are bowtied or chevroned. These zones are marked
by a B or a C, respectively (if rez_mark is set).
