some always present (programs were new in Netpbm 10.52.00
(October 2010)).

September 2011).
pamcomp: remove debug trace message with -mixtransparency.
Always broken. (-mixtransparency was new in Netpbm 10.56,

silently instead of with a clear error message in an environment
that does not provide Unix process management. Always broken.
(pm_system_lp and pm_system_vp were new in Netpbm 10.40
(September 2007), but wouldn't even compile until Netpbm 10.42
(March 2008)).
installnetpbm: Accept globs for directory name responses
(notably, ~/DIR).
makeman: Make it work with Python 3.6.

exists (so don't require ppmdcfont to exist). Broken around
Netpbm 10.35 (2006).
Build: Define _XOPEN_SOURCE=500 in source files that use M_PI.
While C libraries in the past have always provided this with
just _XOPEN_SOURCE=null, it appears that M_PI is actually
defined by Single Unix Specification 2, aka UNIX98, for which
you need _XOPEN_SOURCE=500, and Cygwin has changed to enforce
this.
Build: document MinGW _XOPEN_SOURCE incompatibility and add
warning to Configure.
Debian packaging: fix bug: don't try to include Manweb files, as
it is no longer packaged by 'make package'.

ppmpat: Add -argyle1, -argyle2.
pnmtotiff: Fail with -miniswhite or -minisblack on color image
rather than produce an invalid TIFF.
tifftopnmcmyk: Default rows per strip to the TIFF library
default instead of whatever yields 8K strips.
--version global option: with SOURCE_DATE_EPOCH environment
variable, display source code datetime instead of build
datetime. And when displaying build datetime, do it in the
local time of the process running the command instead of the
process that did the build.

can be represented as a C unsigned integer. Broken in Netpbm
10.11 (October 2002).

libnetpbm: ppmd_fill_path: remove debug trace. Always broken
(ppmd_fill_path was new in Netpbm 10.34 (June 2006).
Build: don't create pointer man pages anymore. These were
classic man pages, created by 'make package', one for each
program, that just told the user to get the manual from the web
and that other options for manuals are available at install
time. Getting documentation online is commonplace enough now
that the user doesn't need to be told to do it or that there are
other options. The existence of pointer man pages was,
meanwhile, misleading, since it looked from the outside like
they actually contained documentation.
Build: Don't package or install Manweb setup (for accessing
manuals on the web with Manweb). Probably 100% unused and
distracting.
Debian package: change dependencies to be compatible with
Debian 8.
16.12.25 BJH Release 10.77.00

Netpbm 10.72 (July 2015).

same filesystem as the output file. Always broken (pnmremap was
new in Netpbm 10.58 (March 2012)).
pnmquantall: Fix incorrect handling of when the Pnmremap or
the final rename fails. Always broken (pnmremap was new
in Netpbm 10.58 (March 2012)).
giftopnm: Fix bug: crash on little-endian computers that can't
toleration unaligned memory access. Thanks Ignatios Souvatzis
(is@netbsd.org). Broken in Netpbm 10.47 (June 2009).
cmuwmtopbm: Fix trivial memory leak. Always broken (cmuwmtopbm
was in primordial Pbmplus, in 1988).
Build: Add PKG_CONFIG make variable.
Build: tifftopnm.c: Fix undefined WIFSIGNALED, etc.
16.06.26 BJH Release 10.75.00

ppmfade, ppmrainbow, ppmshadow, pbmtox10bm, pamstretch-gen:
Add -version.
fiascotopnm: Change -version to include Netpbm version.
libnetpbm: Add pm_system2(), pm_system2_lp(), pm_system2_vp() -
same as pm_system(), etc. but returns the termination status.
pamarith: Fix incorrect output when maxvals differ, for
-add, -multiply, -mean, -min, -max. Broken in Netpbm 10.41
(December 2007).
pbmtextps: Fix bug: input text or font name with Postscript
control characters messes up the Postscript program. Always
broken (pbmtextps was new in Netpbm 10.0 (June 2002).
hpcdtoppm dummy version: Update web link to real version.
ppmhist: Fix incorrect color names. Introduced in
Netpbm 10.19 (November 2003).

compiler.
16.03.27 BJH Release 10.74.00
pbmtext: Produce same image when you run pbmtext with -width
explicitly set to the width you get when you don't specify
width.
pbmtext: Ignore -nomargins when -width is specified.
pbmtext: Report when line ends are dropped because of
truncation.
pbmtext: Fix bug: if input has a code point that is not in the
font, Pbmtext substitutes space, but behavior is undefined if
font doesn't have space either. Now it aborts the program in
that case.
pbmtext: Fix bug: Respect -width when specified.
pbmtext: Fix bug: Deal correctly with negative -space.
pbmtext: Fix bug: Consider all characters in line, not just
first and last, in determining line width.

15.12.26 BJH Release 10.73.00
anytopnm: use --mime-type option instead of --mime on newer

program as indicating PAM.
pnmtops: fix bug: always thinks -level=N is -level=1.

NetBSD: show actual numbers in messages instead of "f" or
no information, by using NetBSD's vasprintf.
Make %g in messages display the actual number instead of "g" in

to ignore every other option (like -version) was new in Netpbm
10.10 (October 2002).
cameratopam: fix buffer overflow. Always present. (cameratopam
was new in Netpbm 10.28 (June 2005)).

Netpbm 9.25 (March 2002) and Netpbm 10.11 (October 2002)).
Build: change _XOPEN_SOURCE from 600 back to 500 in 7 files. It
was changed from 500 to 600 in Subversion revision 1731 in
Netpbm 10.60 (September 2012) because that made a similar
version of Netpbm compile on Mac OSX. Without it, strdup did
not get defined. But this is apparently a bug in Mac OSX, since
X/Open 500 does have strdup. Furthermore, many other Netpbm
files use strdup and apparently compile OK on Mac OSX without
600. Finally, we see today that Illumos system header files
deliberately kill the compilation if the compiler is pre-C99 and
_XOPEN_SOURCE is 600. So we go back to 500 and if the problem
on Mac OSX gets reported again, we will look more deeply.
Build: change _XOPEN_SOURCE from 600 back to 500 in
jpeg2ktopam.c and pamtojpeg2k.c. It was changed from 500 to 600
in Netpbm 10.41 (December 2007), reportedly to get int_fast32_t,
etc. defined on AIX, but other files that use int_fast32_t
don't have it today, so that must be wrong. See above for the
drawback of 600.
Build: fix undefined symbols in fiasco converters with
static libraries.
Build: provide means of setting the default search path for
rgb.txt color database via config.mk.
Build: fix bug which prevents JBIG converters from building with
internal JBIG library. Introduced in 10.67.00.

attempted only on a system with libvga). Introduced in Netpbm
10.63 (June 2013)

Build: fix build failure on SCO OpenServer due to SIGURG not
existing. Broken in Netpbm 10.49 (December 2009).

on Standard Error as a Netpbm message.

in Netpbm 10.53 (December 2010). Thanks Akira F Urushibata

pamstereogram: Add -guidetop and -guidebottom options to replace
trick where negative -guidesize means top, positive means

Clang. (Note that Clang identifies itself as GCC).

latter are not present in Mingw builds.
Build: fix bug finding X libraries for merge buildl
Build: redo conditional compilation of Windows to use
MSVCRT, based on _WIN32, instead of WIN32.

Add pamrecolor. Thanks Scott Pakin.
anytopnm: Use 'pngtopam' shell command instead of 'pngtopnm'.
pnmtopng: -libversion doesn't report level of linked libz.
It was a modularity violation and caused build failures on
Mac OS X, because pnmtopng per se doesn't know about libz --
it's used by libpng.
libnetpbm: add pm_readbiglong2, pm_readbiglong2u,
pm_readlittlelong2, pm_readlittlelong2u: These use the proper

in libc.
configure: don't default to /usr/X11R6/lib/libX11.so just because

strange combination of luminosity and HSV value.

uses -matrix).
pnmtofiasco: fix bug: doesn't work with Standard Input.

09.09.27 BJH Release 10.48.00
ppmsvgalib: Wait to initialize Svgalib to prevent it from
interfering with error messages early code might issue, and

exiting.
Remove pngtopnm from the package. Pngtopnm is now an alias
for Pngtopam.

pnmremap: fix -missingcolor: where map file (ergo output) is not
depth 3, uses an arbitrary color.
pnmremap: fix loss of dithering when the map (and thus the
output) has lower maxval than the input. (Old code scales down
to the new maxval before dithering).

ppmpat: fix crash when width or height is zero.
ppmpat: fix wrong output with -poles.

Lots of changes to integer code, bit access, word access, etc.
None functional. Some speedup.
make distclean: remove lib/compile.h.
configure: use TEMP environment variable for TMPDIR if TMPDIR

since March 2004, when it was found to work better than 250,
which is the number documented as right.
ilbmtoppm: fix bug: appends color map PPM to output if input
has color map; fails if input doesn't have color map. Broken

interfere with finding the built libnetpbm. (The common
link rule is already this way in Netpbm 10.44.00; all the other
link rules are now the same).
Build: Rename Makefile.common, Makefile.config, to common.mk,
etc.
