<H1>WIP Version 2.1 Changes</H1>
This version reflects corrections and enhancements to WIP (Version 2.1):
<OL>
<LI> Flipped the sense (direction) of the color palettes. This will
affect previously defined scripts but it is better to get the
correct form now than to confuse others down the road. The impact
of this is also seen in the <CODE>wedge</CODE> routine.
Also added <CODE>palette 0</CODE>
which is a ramp from the background color to the foreground color.
This palette is now the default when a new device is chosen.
<LI> Added the <CODE>beam</CODE> command. This pointed out the need
to fix the arc subroutine. It was drawing incorrectly when an axis
direction was reversed (eg. X-axis as RA). Now all angles increase
counter-clockwise as per documentation and regardless of axis orientation.
<LI> Added a file in the Examples directory that defines a macro which
can handle FITS files with the CDx_y matrix (common in HST images).
This also demonstrates how to specify the transformation matrix for
images with arbitrary rotation.
<LI> Added an optional argument to the <CODE>image</CODE> command that
will permit smoothing of the input image data.
<LI> Added optional arguments to the <CODE>halftone</CODE> command that
causes histogram equalization to be performed on the color LUT. A
blank value can also be given for the histogram algorithm to ignore
when computing the data histogram.
Only the selected subimage is counted.
<LI> Modified the <CODE>wedge</CODE> command. This permits user defined
tick arguments (with <CODE>ticksize</CODE>) to get used. The change
also requires the user to provide <CODE>box</CODE> command-like
arguments if they want a box around their wedge. Now, if the user
wishes a label associated with the wedge, they need to do it with a
separate label command (like <CODE>mtext</CODE>).
<BR><STRONG>Note:</STRONG> This change of the label argument to a
box drawing one is not backward compatible.
<LI> Modified the <CODE>panel</CODE> command to allow a negative third
argument. If it is negative, then the panel ordering goes left to
right and top-down.
<LI> Modified fits.c driver to permit BITPIX=8 (byte) images.
<LI> Modified inoutput.c and declare.h to recognize NOVARARGS flag.
This was added for those systems that don't handle varargs.h properly.
<LI> Modified error bar routine to permit locations 5 and 6. Now
all the checking for proper location values is handled by PGPLOT.
<LI> Fixed makewip and wipdefs.h for OSF/1 compilations. It was
defining alpha but that was used as a variable in some routines.
Changed alpha definition to OSF. (I hope this is generic enough.)
<LI> Added subroutines wip[gs]etcir so the color index range changes
would directly affect the user variables cmin/cmax.
<LI> Corrected the way color index ranges are tested in histo.c and
points.c and how cmin/cmax are initially defined when a device
is opened. Histo.c and points.c now get the full color index
range permitted for the current device rather than the range
specified by cmin/cmax. When a new device is opened, cmin/cmax
are set up to be the same values as internal to PGPLOT (ie. cmin
is always 16 and cmax, if smaller, is set to 0). Palette.c was
also modified to limit the palette range to indices larger than
(or equal to) 16.
<LI> Changed sysdepunix directory to just sysdep. The script makewip
was modified accordingly.
<LI> Created a new directory called fit, moved plot/linefit.c into it,
and then split the individual fitting routines into their own files.
The script makewip was modified accordingly. This included the
addition of two different polynomial fitting routines.
<LI> Added the command line option "<CODE>-e cmd [args]</CODE>" which
permits one to issue an initial command. It is executed after the
files are read and before the -x option is checked.
<LI> Added the cyclic palette (option 12). Thanks to georg@itpgyro1.fzk.de
for suggesting it.
<LI> Created a log directory and put the files of changes (like this
one) in it. Also converted them to HTML so they could be accessed
from the WIP home page.
<LI> Changed the default action of basic images to NOT byte-swap.
Since basic images are usually created locally, they are probably
stored in the native format. However, I also added the ability
for users to override this default by specifying the image type
with an upper case letter.
