WIP Version 2.2 Changes
This version reflects corrections and enhancements to WIP (Version 2.2):
- Corrected a bug in the image driver routines. A variable wasn't
declared large enough and so some headers caused memory overwrite.
- The previous version of WIP (2.1) had removed a comment in the
parsing routine for the cursor command. The command then issued
(incorrectly) an error message. The null command has been reinserted.
winadj command in the image2.wip file in the
Examples was incorrect. This has been corrected.
- Re-inserted the stdin option to the command line. This is now
done using the convention of a double minus sign (
- Added the command line option
-q to enable quiet
mode so no informational messages are written to stdout. This will
be useful for plot devices that use stdout as their file. It
should probably be used with the
-x command line option.
It is turned off when interactive mode is started.
- In version 2.1, the
arc command was corrected to
agree with the documentation that angles increase counter-clockwise.
This made WIP not backward compatible for this command. The fix
for those with previous macros is the following. Suppose you had:
Then, make the following change:
- set \0 180 - start
- arc maj min -angext \0
If you also use the
- set \0 180 - start - angext
- arc maj min angext \0
angle command to rotate the entire arc,
then you must also multiple its argument by -1.
- Debug mode was changed from a global variable to a subroutine.
This included adding a new user variable (debugmode).
wedge command has changed (again). It now
has a simple default box argument if none is provided by the user.
It appears most people will want a basic box (BCSTN/M) and will
only occasionally need to override this default. The examples show
how to override the default; to get no box, use the box option 0.
