--------------------
Wed Nov 13 22:40:52 1996 Frank D. Cringle <fdc@cliwe.ping.de>
* viewfax.c (NewImage): Set bitmap_unit to 32. (Fixes garbled
images on some 8/16-bit oriented servers - found by
bod@tyndall.com.au (Brendan O'Dea)).
Thu May 9 16:16:36 1996 Frank D. Cringle <fdc@cliwe.ping.de>
* All files: FSF address changed.
* viewfax.man: add URL for faxview.

--------------------
Version 2.3 released
--------------------
Sun Oct 15 11:23:01 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* viewfax.c (drawline): interpret LineNum parameter within strip.
(GetImage): iterate over strips of multistrip image.
* faxinput.c (notetiff): grab whole directory into memory. Don't
treat non-fax tiffs as raw files. Put strip info in an array
rather than a linked list. Accept compression mode 2 (MH).
(getstrip): was getpage.
* faxinit.c: initialise table entries for extension codes.
* faxexpand.h: change strips in pagenode from list to array.
Declare MHexpand, getstrip.
* faxexpand.c (expand1d): detect and warn about extension codes.
(I chickened out of actually processing them).
(expand2d): correct bug in EOL handling.
(MHexpand): new routine.
(g31expand, g32expand, g4expand): loop limit is rowsperstrip, mot
height.
(g4expand): semi-fix RTC detection (still does not allow for
padding).
Sat Oct 14 11:27:03 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* viewfax.man: faxview.tcl was viewfax.tcl (got hit by a global
replace). Added Shift-Q, L, M, U keys.
* Imakefile: add definition for MANDIR. The helpfile is nonexec.
Don't define local directories if freebsd.
* viewfax.c (ShowLoop): New keypress meanings:
Shift-Q - terminate with prejudice (requested by Ralph Schleicher).
Shift-L,M,U - rotate this and all following pages (requested by
Viet Hoang).
--------------------
Version 2.2 released
--------------------
Mon Sep 11 10:21:17 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* viewfax.c (GetImage): this routine must return a status
indicating if getpage() failed. Its callers must try again until
it succeeds (to deal with missing pages).
Sun Sep 10 17:31:39 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* viewfax.man: update to reflect new functionality.
* viewfax.c (main): TIFF is no longer optional (the help page is a
tiff file).
(ShowLoop): display help page if requested. Accept BackSpace key
for previous page. Mirror image if requested.
(ZoomImage): the pb1 pointer could overrun the end of the Big
image by one word if an odd number of Big words fit in a Small
line.
(MirrorImage): new routine.
* faxexpand.h: keep a list of strip offsets in pagenodes instead
of a single offset to the fax data in a file. Add the
mirror-image orientation flag. Remove WITH_TIFF.
* faxinput.c (notetiff): handle all 8 orientations. Handle
multi-strip tiff images. Remove WITH_TIFF.
* faxexpand.c (SKIP_EOL): don't set a0 = lastx after an error, it
is a lie that prevents the line being properly filled out.
(g31expand & g32expand): report incorrect line length if verbose.
* Makefile (CFLAGS): remove -DWITH_TIFF - it is no longer
optional. Add g3hack and the HELPFILE. Add -ansi -pedantic to
gcc flags.
* Imakefile: remove WITH_TIFF, add HELPFILE.
* README: make / make depend in wrong order. Remove comment about
WITH_TIFF.
Wed Jun 21 09:44:25 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* Updated the FSF address in all file headers.
--------------------
Version 2.1 released
--------------------
Wed Apr 12 11:24:34 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* faxexpand.c: simpified access to raw data by preprocessing it
into 16-bit lsb-first chunks. Ensure all macros are either
expressions or statements (not blocks).
* faxinit.c: build tables for access with lsb-first bit order.
* faxinput.c: new source file containing routines moved from
viewfax.c.
* viewfax.c: moved the input file processing to a separate source
file (faxinput.c) in preparation for use with other utilities.
Eliminated G3desc and made the expansion routines use pagenodes.
----------------------------------------------------------------
Renamed again due to name conflict with hylafax/contrib/faxview.
Now call viewfax.
----------------------------------------------------------------
Fri Apr 7 18:10:35 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* Version 2.0 released.
* faxexpand.c: new expansion routines g32expand() and g4expand().
Caller provides a pointer to the line drawing routine for future
flexibility.
* faxview.c (main): new options -2 and -4.
(drawline): moved out of faxexpand.c.
* README: Mention g4, WITH_TIFF.
----------------------------------------------------------------
Renamed from g3view to faxview to reflect new functionality.
----------------------------------------------------------------
Sat Apr 1 21:06:55 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* Version 1.9 released to testers.
* g3view.man: mention tiff and hylafax. Document new keys for
previous/next page.
* g3view.c (notetiff): new function which figures out where the
raw image data is in a tiff file.
Fri Mar 31 12:17:53 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* g3view.c (usleep): added to the list of systems which have
usleep in libc.
(SetupDisplay): restrict the initial window size to the physical
screen size even if the virtual root is bigger.
(ShowLoop): allow '-' as a synonym for previous page and '+' and
space as synonyms for next page.
Sun Feb 26 15:31:53 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* Version 1.8 released.
* g3view.c (getpage): report memused (in verbose mode) after
generating the new image.
(SetupDisplay): fixed problems with negative geometry coordinates.
(ShowLoop): improved the handling of user window-movement and
resizing. Maintain image position when it is zoomed in a
constrained window size.
Thu Feb 16 12:18:38 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* g3view.c: #define XLIB_ILLEGAL_ACCESS is required by SCO- (and
maybe other) systems in order to access the contents of the
Display structure.
(RotImage): fixed boundary problem.
(main): allow any abbreviation of -display and -geometry.
(ShowLoop): process all pending key- and button-presses before
updating display. Ignore key and button presses while the window
is changing size, otherwise the image size and window size can get
out of sync.
(ShowLoop): don't jump to the top left if -geometry constrains
size but not position.
Wed Feb 15 13:21:36 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* Version 1.6 released.
* g3expand.c (G3init): finally killed the gentab -> g3tables
precomputing step, in favour of run-time initialisation. Time for
G3init is down in the profiling noise.
* g3view.c (SetupDisplay): use the size of the root window rather
than the size of the screen as the maximum possible geometry.
(ShowLoop): use the user-specified geometry (default: entire root
window) to constrain the area available to g3view.
* g3view.man: get rid of -x and talk about window managers.
Tue Feb 14 20:55:57 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* g3view.c (ShowLoop): another change to the window resizing
logic. It now works as desired with all window managers except
fvwm. Use g3view -x25 under fvwm until fvwm gets fixed.
* g3view.man: documented -r and -x
Sun Feb 12 18:45:28 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* g3view.c: added command-line-settable display and geometry
values, dynamic bit-reversal of input files and warning bell
(audible/visible) when attempting to move to non-existent page.
Removed -m and -x window-manager kludges. -m now gives limit to
image-memory cache size.
(getpage): delete the mmap() version. We now always suck the
input file into memory so we can optionally bit-reverse it and so
we can add zeros at the end to prevent the expansion algorithm
over-running without having to check each byte. Also survive
unreadable or empty files by removing them from the file list.
(GetVRoot): took this function from the comp.windows.x FAQ. I
can't test it 'cos I don't have the solbourne virtual WM around
here.
(SetupDisplay): process user's geometry spec.
(ShowLoop): try to cooperate with the window manager by tracking
Reparent and Configure events. Use NewImage() and FreeImage() to
manage cache size. Give warning when there is no previous/next
page. Allow zooming with z/Z.
(RotImage): provide faster version which does 4 rows at a time.
* g3expand.c: removed the compile-time REVERSE option (we now have
an equivalent at run-time). Removed 2D states from debug list.
(G3expand): Added line number to error messages. Tightened up
end-of-data detection to prevent core dumps.
(G3count): Continue counting after spurious EOLs (for
efax-mutilated digifax files).
* g3.h: removed unused 2D state definitions.
* README: recommend Imakefile.
* Makefile: $(HAVE) is no longer needed. Added -Wno-uninitialized
to suppress uninteresting warnings in new RotImage() code. Added
Imakefile to FILES.
* g3view.man: renamed from g3view.1 to comply with Imake
convention. Added documentation of new features.
Mon Feb 6 12:42:14 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* Version 1.4 released.
* Makefile: don't need _HAVE_XSETWMPROTOCOLS any more.
* g3view.c: added -m and -x flags. Avoid using SetWMProtocols for
compatibility with ancient installations. Release non-essential
memory and retry if a malloc or Xcall fails.
* g3view.1: documented -m and -x flags.
Sat Feb 4 12:43:50 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* g3expand.c (G3expand): fixed a malloc bug (not enough memory
requested for run-length list).
Fri Feb 3 11:10:48 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* g3view.c: Support a list of files on the command line rather
than just a single page.
* g3view.1: Updated to reflect new functionality.
* g3view.c (ZoomImage): still didn't work on little-endian
hosts. It now operates on 32 bit words and should be
architecture-independent (and faster). Three versions are
available via #ifdef.
(SetupDisplay): it is unnecessary to constrain the minimum window
size.
(ShowLoop): changed the image scrolling method (middle mouse
button) to actively chew through the event queue instead of
waiting for motion hints. The old method is still available if
USE_MOTIONHINT is defined.
(SetupDisplay): fix a rounding problem with the initial window
size.
Thu Feb 2 23:00:00 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* Version 1.2 released.
* Makefile: tar and shar targets added.
* g3view.1: update to reflect changed middle button handling.
* g3view.c: added version number and "COPYING" reference to usage
and verbose messages. Removed arguments from getopt() prototype
(there is no consensus about if, where and how it is declared).
Fixed problem with window size constraints when running under mwm.
(ZoomImage): corrected packing order on little-endian hosts.
(ShowLoop): improved middle button handling (now it drags the
image rather than making it jump).
Tue Jan 31 18:00:00 1995 Frank D. Cringle <fdc@cliwe.ping.de>
* Version 1.0 released.
