There have been many many bug fixes and improvements since the last
packaged release. SVG, PDF, and DXF output is available now. The complete
list (>200 lines) is in the CHANGES file in the distribution.
Summary of changes:
- removal of USE_GTEXINFO
- addition of mk/texinfo.mk
- inclusion of this file in package Makefiles requiring it
- `install-info' substituted by `${INSTALL_INFO}' in PLISTs
- tuning of mk/bsd.pkg.mk:
removal of USE_GTEXINFO
INSTALL_INFO added to PLIST_SUBST
`${INSTALL_INFO}' replace `install-info' in target rules
print-PLIST target now generate `${INSTALL_INFO}' instead of `install-info'
- a couple of new patch files added for a handful of packages
- setting of the TEXINFO_OVERRIDE "switch" in packages Makefiles requiring it
- devel/cssc marked requiring texinfo 4.0
- a couple of packages Makefiles were tuned with respect of INFO_FILES and
makeinfo command usage
See -newly added by this commit- section 10.24 of Packages.txt for
further information.
Changes are:
Bug fixes:
- Added polygon mode support for CI
- Label characters from unsupported fonts are now replaced by their
charset 0 equivalents instead of being replaced by blanks.
- Text was sometimes incorrectly clipped when IW was set
- Fixed a typo (missing parenthesis) in the Sun5 part of generic.mak
- Polygon fills were (again) miscalculated in some cases
- The 'pen dot' feature was unnecessarily adding dots for the segments of
polylines as well
- PS command with height only and PS with width>height were not treated
correctly, rotation and scaling were applied twice due to code duplication
- small (cosmetic) corrections to the new linetype code (A. Bird)
- lines drawn in IW mode had extraneous pen-up moves added, which confused
the line pattern generator.
- clipping (IW) was seriously broken by cleanup and prototyping efforts in
ALPHA2/3. Thanks to Andrew Bird for finding and fixing this.
Auto-generation of output filenames sometimes failed (side effect of
the less restrictive naming rules introduced in ALPHA2)
- removed extraneous asterisk in the INFO-DIR-ENTRY section of the
texinfo doc file (Reinhard Kotucha)
- IW without parameters was assigned wrong values in some cases (bug
introduced in ALPHA2)
- IW could clip lines just inside the limits due to rounding errors on
some platforms
- chanell makefiles to include fillpoly.(c,o)
- Line pattern length was too long for LT-2
- SC scale factors were not applied to XT/YT tick marks, resulting in
distorted plots
- Added a #define to support compiling on WinNT (mentioned, but not
actually included in ALPHA2)
- deactivated the excessive debug output in the fill code (which could lead
to huge temporary files)
- made the simple scanline algorithm a bit more robust (but it still gets out
of step in a few pathological cases - which means that filled and unfilled
sections will be reversed for the remainder of that line)
- enclosed all references to the unfinished Epson driver in #ifdefs, so that
it is not built by default. (also fixed a few glaring bugs in the esc/p2 file
header code, but the driver still does not work _at_all_)
- absolute PW pen widths between 0 and .1 were accidentally rounded to zero
(invisible lines)
- the picture border was too wide in some cases (Gerhard Buergmann)
- IW limits were interpreted as plotter units even if scaling (SC) was set.
- PCX output sometimes had dark red background in b/w mode and wrong colors
in colormap mode (rewrote to_pcx.c for PCX5, see above).
New Features:
- Support for HPGL/2 commands related to polygons and area fills :
EP, ER, FP, FT, PM, PT, RA, RR, WG (no user-defined fill types yet)
- WU command support, PW fixed accordingly.
- AT,RT command support (arc through three points)
- Initial (non-functional) version of an Epson Esc/P2 driver based on
to_pcl.
- Parser improved to be more robust (especially with PE commands),
cliping (IW) support for PE lines, PJL and RTL control sequence handler,
type 1 and 2 (anisotropic) scaling support added to SC (Eugene Doudine).
- Modified to_pcx to produce PCX mode 5 (truecolor) files in color mode,
PCX2 in monochrome. (The old PCX2 module is in the 'old' directory, in
case this proves to be worse - i have changed a few of the palette
definitions to get correct b/w output and primary colors even with this
version).
- New linetype handling including support for line types 7,8,-7,-8 and
user-defined linetype (UL) (written by Andrew Bird)
- Support for the COmment keyword added (Andrew Bird)
- PD;PU-sequences without pen movement create a small dot now to mimick the
behaviour of a real pen plotter.
- Added -S option for selection of TIFF compression mode (Andrew Bird)
- Rewrote pen property handling - a pen can now change width during a
plot (Andrew Bird). Similarly added pencolor changing support (though for
the postscript driver only - all other modes require a rewrite of the
intermediate raster 'picbuf' code).
- Output mode 'esc2' for the Epson Stylus series of printers at 720dpi.
(limited to A4 size for now, and in 'microweave' mode, i.e. using only
one row of nozzles, which results in exact but very slow printing)
- added command line option '-n'/'--nofill' to suppress polygon filling
- OS/2 PM previewer now has stderr output redirection to a separate window
(patch provided by Kazutaka Nishiyama)
- Added step-by-step instructions for compiling on Windows NT (provided by
James D. Shaw)
- X11 preview generates a warning, but no longer aborts if the window is
larger than the current screen size
- file names may start with non-alphabetic characters (e.g. numbers
or unix-style path names) now (Michael Kennedy)
