Rev: 1/2/92 (version 2.00)
-----------------------------
*** SUN Rasterfile support (Dave Heath (heath@cs.jhu.edu))
fixed unclosed comment in xv.h (Paul Close (pdc@sgi.com))
fixed infinite loop in Imakefile (Kjetil Jorgensen (jorgens@lise.unit.no)
fixed problems in Imakefile (bitmaps.h wasn't being rebuilt)
(Jonathan Kamens (jik@pit-manager.mit.edu))
additional bug fixes/workarounds for 24/32-bit TrueColor displays
(Dave Gregorich (dtg@csula-ps.calstatela.edu))
include string.h or strings.h based on 'SYSV' flag
(Kevin Brown (brown@hpbsm15.boi.hp.com))
bogus command line parsing ('-autogamma' wouldn't work)
(Doug Washburn (washburn@hpmpea2.cup.hp.com))
fixed 4-bit X code to work on MSBFirst machines
(Stefan Esser (se@ikp.Uni-Koeln.DE))
mods for HPUX 7.0 (Jan D. (jhd@irfu.se))
added window classes 'XVroot', 'XVcontrols', 'XVdir', 'XVinfo', and 'XVcedit',
so Motif users can do things like this:
Mwm*XVroot*clientDecoration: none
Mwm*XVcontrols*clientDecoration: -resizeh
Mwm*XVdir*clientDecoration: -resizeh -maximize
Mwm*XVcedit*clientDecoration: -resizeh -maximize
Mwm*XVinfo*clientDecoration: -resizeh -maximize
Also, WM_DELETE_WINDOW is now set up in the WM_PROTOCOLS
property, allowing the 'close' menu selection under MWM to
close an XV window without terminating the application.
(Jan D. (jhd@irfu.se))
slow 24-to-8 conversion was moving the image down 1 scan-line
(Satoshi Asami (asami@is.s.u-tokyo.ac.jp))
mods for MIPS machines (David Boulware (dgb@landau.phys.washington.edu))
Ability to LOAD pictures that weren't specified on the command line
fixed bug in CheckForConfig()
twm workaround from patchlevel 2 now only turned on if '-twmkludge' option is
specified. Was causing problems on OpenLook 2.0 systems
directories and symbolic links are now sorted together at the top of
the 'xv directory' list
fixed crashes when 'AutoCropping' in conjunction with '-root' option
file format/color buttons in Directory window are now set whenever an image
is loaded. (Set to the format/color of the loaded image.)
clicking anywhere inside the Info box will now close it
added support for up/down arrows, page up/down, home, and end keys when
mouse is in control window or directory window (for operating
the scrollable list thingy)
changed 'Return' key binding to mean 'display currently selected picture'
rather than 'Next'
added binding of Tab key to 'Next' function
'-wait' now waits until picture is fully up on screen before starting timer
'-wloop' option added. Causes '-wait' slideshow to loop at end
added 'hagan-style' tiling on the root window. '-root', '-center', and
'-rpat 0' (the default) will now draw an image centered on the
root window, with images going off the screen in all 4 directions
(Unlike 'normal' ('-root' only) tiling, which has one image
pinned in the top-left corner of the screen, and subsequent
images going off the screen ONLY on the bottom and right sides)
added '-maxpect' option. (An abbreviation for '-center -fixed -max')
makes the image as large as possible, without changing the
aspect ratio. Only relevant when used in conjunction with
'-root'. (When not using '-root', both '-max' and '-maxpect' do
the same thing (as large as possible without changing the aspect).
When USING '-root', '-max' makes the image the size of the screen,
in all likelyhood changing the aspect ratio)
added '-olwm' option (and xv.olwm resource) for people using Sun's OpenLook
window manager. Makes the window behave correctly when resized via
any of the xv resizing commands.
added new, slicker-looking icon. The old one was outside Motif's accepted
range of icon sizes.
SMOOTHING controls (Smooth, Dither, and Raw buttons) added
added '-cursor' option (and xv.cursor resource). Allows you to pick a
different cursor for the image window (instead of the
default crosshair cursor)
various modifications to work somewhat better with tvtwm (or other
virtual window managers)
Hitoshi Saji saji@is.s.u-tokyo.ac.jp
Tetsuya Ikeda tetsuya@is.s.u-tokyo.ac.jp
Satoshi Asami asami@is.s.u-tokyo.ac.jp
fixed up some multiple-redraw bugs, for improved speed
Added spiffy 'hue' and 'saturation' dials to cedit box
New format for '-GAMMA' command line option and gamma resources. Fully
specifies state of gamma controls, including 'lines/spline' and
'rgb/hsv' modes
Improved 'undo' handling in Gamma box.
Added 'reduced' color save. Used in conjunction with the '-nc' command
line option. Saves the image more-or-less 'as shown', rather than
"as it's supposed to be". For example, you can now save bizarrely
stippled pictures by doing something like '-nc 0 -wh red -bl blue'
on the command line, and then saving the image in 'reduced color'.
added '-adither', '-asmooth' options (and 'xv.autoDither', 'xv.autoSmooth'
resources) to automatically dither or smooth the image upon
loading it. Mainly for use the case where you want XV to
load an image onto the root window and go away without any user
intervention. (Like you might put in a startup script.)
added some X error handling so that XV doesn't blow up (ungraciously) when
you're using '-root' on an X terminal that doesn't have enough
memory to do a full-screen root image
code reorganization: xv.c and xvmisc.c have been split into (xv.c, xvevent.c,
xvroot.c) and (xvmisc.c, xvimage.c, xvcolor.c, xvsmooth.c)
respectively. The files were getting annoyingly large.
added colormap editing capabilities to the gamma box
Colors can be edited in either HSV mode or RGB mode
You are modifying the original colormap of the image, BEFORE
the '-mono' or '-rv' options are applied, BEFORE
any GAMMA correction is applied, and before it's
determined how to get the image on the screen.
As a result, it's best to edit colors when the GAMMA
controls are set to 'Linear'
You can select the color to be edited by clicking in the colormap
area of the GAMMA box, or by clicking in the image window
(in which case the color selected will match the last pixel
value you displayed)
Using '-rw' mode will generally speed things up, but isn't
necessary.
added colormap 'grouping'. Use Button3 to add/delete color cells from the
current group. Hold shift key down and the image regeneration
will be delayed until you let go of the shift key. (normally
the image would be redrawn every time you released Button3.)
This allows you you quickly group multiple pixels.
added 'cut buffer' usage. Whenever you track pixel values (by clicking the
left button in the image window), the last pixel values are put in
the X cut buffer, so that you can paste them into your own program,
an xterm window, or whatever. Useful if you're using XV to choose
'points-of-interest' to be used as input to another program.
Also, if you click on the gamma values (above the graph in the
gamma window), those values will be put in the cut buffer as well.
(Handy for setting default values for the Gamma resources.)
added a slightly-improved 'cropping' rectangle. Should show up better on some
pictures.
added hsv pixel display. When tracking pixel values in the image window
(with the left mouse button), the values will either be displayed
as R,G,B components (0-255), or as HSV components (0-359, 0-100, 0-100)
This is based on the setting of the HSV/RGB switch in the Gamma box.
added a 'Randomize Colors' button. (keyboard equiv: 'R').
Causes the entire colormap of the current picture to be
randomized. Groupings *will* be respected, however. (ie, all pixels
in a group will still have the same color, albeit a new one). For
amusing effects, do some by-hand color reduction (by grouping all
similar colors), then do the randomize function.
added an 'Undo All' button in the Gamma box. Undoes all changes made to the
image's colormap and clears all groupings.
added '-hsv' and '-rgb' switches (and xv.hsvmode resource (boolean)) to
allow user to set initial hsv/rgb mode. By default, program uses
RGB.
fixed 'shift key' bug with regards to entering filenames in dir window
'enter' in file i/o window now opens the currently selected directory
fixed bugs on 1-bit displays (fish cursor didn't flap during re-ditherization,
CMap wasn't properly refreshed after loading new pic)
Smooth/Dither now sets 'Current Size' RButt in file i/o box. (Need to save
at current size to save 'smoothed' picture.)
BadAccess errors cause by XFreeColors are now ignored, as this is simply a
sign of a busted X server, and happens when multiply-allocated
colors are freed more than once. (like they're supposed to be)
Should make '-bfc' option obsolete.
Current Size RButt ripped out. (Always saves at current size)
flapping fish cursor added during PBM/PGM/PPM file i/o
created GRAF type
MASSIVE modifications to GAMMA box
Gamma box renamed 'Color Editor' box ('cedit')
Added direct numeric gamma input to GRAF boxes
Created HDIAL controls
Changed non-range HDIAL to be a hue/saturation control
Created CBUTT check boxes
Added 'drag the whole range around' feature in range HDIALs
Added -nopos, -fgeom, and -fmap command line options (and resources)
Fixed 'crop near corner' graphics bug
Fixed multiple redraw bug, with any luck.
Added '-2xlimit' option and resource. Allows the image window to be larger
than the screen (up to 2x). *NOT* recommended unless your WM
is capable of operating windows without visible borders. (ie, you'll
need some meta-mouse-button action, ala twm/uwm...)
Added rudimentary GIF89 reading. (Jon Brinkmann, jvb7u@astro.Virginia.Edu)
Changed ISTR_INFO to be more to Hagan's liking.
(eg "320x200 GIF87. Got all 37 colors.")
Fixed some probs in xvsunras.c
(didn't understand RT_FORMAT_RGB, and RT_BYTE_ENCODED 8-bit
rasterfiles didn't load correctly, nor did it handle odd-width
24-bit images correctly)
Added POSTSCRIPT OUTPUT and PostScript Box (7/6/91)
Drag the image window around on the page with the mouse. The scale
controls are used for stretching. Note: if you use the arrow keys
(regular and shifted), you can get precise positioning control.
Added GIF89 aspect ratio handling, warning message about skipped extensions,
PlainText block handling (doesn't do anything with it)
Ripped out the '-fish' option and related code. Never worked right anyway.
Added ability to type long strings in 'filename' field of dir box.
Split 'file i/o' button into two buttons 'Load' and 'Save'. Directory box
is now either a 'Load box' or a 'Save box', depending. (^L and ^S
are the accelerators).
Added ability to type pathnames in 'filename' field. And 'cd-ing' to different
directories directly without going through pesky UI.
Added 'popup' windows. (The computer seems to be on fire. <Ok> )
Stretched ctrlW so that 'helvetica' font would still fit (Ultrix 4.2 doesn't
include 'lucida' still...)
Added 'close' (via mwm menu) handling to PostScript window and PopUp window.
Added wait cursor during directory-reading (whenever you change directories)
Fixed PostScript file output (to have correct comments)
Added 'maxpect' button in PS window.
Hooked up remaining buttons in ColEdit window (undo, redo,
brite, dim, sharp, dull)
Got rid of 'recolor' operations when non-visible changes made to Graf's
(changes of less than '2' aren't visible due to coordinate halving)
Added 'max contrast' button to gamma window
Added 'C' and 'R' keyboard equivs for 'MaxCnt' and 'Reset' respectively
Added 'default' picture (xvdflt.c)
Added 'Flip H' and 'Flip V' buttons ('h' and 'v' keyboard equivs)
Redesigned ctrl window somewhat
When you 'Load' files (via the Load dialog box), the file names are stuck
in the 'ctrlW' list for E-Z Re-Viewing...
Added ability to 'reload' current picture (by double clicking on its entry
int the ctrl window list)
Added 'Delete' command. ('^D' keyboard equiv)
Mods to work (better) on Apollo systems
(Robert Goodwill (robert@earth.cs.jcu.edu.au))
Added support for 16-bit displays
(David Elliot (dce@smsc.sony.com))
Improved 24-to-8 color compression routines
(Tom Lane (Tom.Lane@g.gp.cs.cmu.edu))
Improved color selection algorithm
(Tom Lane (Tom.Lane@g.gp.cs.cmu.edu))
Flag resources now accept 'on', '1', 'true', 'yes' in either u/l case
(Chris Weikart (weikart@prl.dec.com))
Fixed potential overflow bug in linear interpolation code
(Chris Weikart (weikart@prl.dec.com))
Added Motif-Style 3-d buttons
Added 'Auto-Reset' check box in ColEdit window
Optimization to ColEdit: if changing a control hasn't actually
affected the 'desired colormap', don't bother applying the change
Changed 'graf' controls: you can now hold down the shift key and modify them
to your hearts content. The image is not actually recomputed until
you let go of the shift key.
Added '-hi' and '-lo' options ('highcolor' and 'lowcolor' resources) for
setting the 'other' two colors on the buttons.
Added '-v' option ('visual' resource) to allow the user to force XV to use a
specific visual type, rather than the server default.
Added gamma resources. Hooked up 'Get Resources' button (copies current
gamma settings into the cut buffer)
Ripped out '-tile', '-center', and '-rpat' options. Replaced them with
'-rmode' option ('rootMode' resource)
Added mirrored tiling and integer mirrored tiling root modes.
PopUp window now pops up with the right-most button centered under the mouse,
rather than in the middle of the screen.
Added '^D' accellerator key (for 'Disk File') in the 'Delete What' PopUp box.
Changed '-asmooth' and '-adither' to '-smooth' and '-dither', respectively.
Added stricter command line argument matching. '-snausage' no longer would
match the '-s' flag.
Changed way '-expand' (and 'expand' resource) works. Now takes floating
point number. For backwards compatibility, negative numbers are
still treated as reciprocals. (ie, both '-2' and '.5' will halve
the image)
Created 'MBUTT' pop-up menu widget.
Added 'Display Modes' popup button.
Fixed bug when using '-perfect'. The XCopyColormapAndFree() function had the
rather undesirable side effect of getting rid of the allocated
colors used for the various windows, etc. (ie, more than the
image colors)
Made 'Hagan-Style' tiling (aka, Centered Tiling) much more efficient
(Robert Potter (rpotter@grip.cis.upenn.edu))
Made the 'directory' listing in the load/save box use an MBUTT.
Added JPEG support. (Markus Baur (s_baur@iravcl.ira.uka.de))
(and, of course, the Independent JPEG Group)
Added '-keeparound' flag (and 'keepAround' resource). By default, if you
'delete' the last file remaining in the ctrl window list,
the program will auto-exit. This option overrides that behavior.
Ripped out '-fgeom' and '-fmap' options (and 'fileGeometry' resource).
Load/Save boxes now come up wherever the mouse is.
Wrote OpenOutFile() and CloseOutFile() routines to unify redundant code
in 'DoSave()' and 'writePS()'
Added 'piped' output. (ie, save file "| lpr")
Added 'Alert' boxes (button-less PopUp's)
Bug fixes when loading/saving '~' files
Fixed PS output to be Encapsulated PostScript compatible
Added a faked 'colorimage' procedure for grayscale PS printers.
(Color postscript files will print on non-color printers, albeit in
grayscale.)
New Window positioning code. Should work for (nearly) all WMs.
(Matthew Stier (matthew@sunpix.East.Sun.COM))
Automatically smooths images that were 'shrunk' (2x, 4x, etc...)
Bug fixes to the JPEG i/o code. (Tom Lane (Tom_Lane@G.GP.CS.CMU.EDU))
Fixed problem in xv24to8.c with the Floyd-Steinberg dithering code.
(Charles Hannum (mycroft@gnu.ai.mit.edu))
Modified 'Delete' behavior. Only loads an image if you deleted the
currently-viewed image.
Changes the suffix of the filename in the 'save window' when you change
file formats.
Got rid of 'Quit XV' buttons in load and save windows
Added extra verbiage to JPEG save window.
Dicked around some more with window positioning code. Seems to work
correctly in TWM and MWM. Hopefully, it'll work in OLWM as well.
Added Makefile options and xv.h #ifdefs for Encore's UMAX
version of Unix System V. (Drew Watson (dwatson@encore.com))
Added '-owncmap' option (and 'ownCmap' resource) to make XV *always*
use/install its own colormap. (Bill Turner (bturner@cv.hp.com))
Rev: 11/29/90 (version 1, patchlevel 3)
-----------------------------
Changed 'CCOPTIONS' to 'DEFINES' in Imakefile
Fixes for use with virtual root window managers (ie, tvtwm)
(only cares about virtual root when using '-root' option,
negative geometry's correctly handled.)
(Andreas Stolcke (stolcke@ICSI.Berkeley.EDU))
Modifications for Sequent machines (no 'mem*() routines)
(Daniel Pommert (daniel@ux1.cso.uiuc.edu))
Modifications to avoid bug in certain optimizers, most notably the default
optimization (-O) in Sun's C compiler. (Incorrectly handles lines of the
sort "*p = array[*p]")
Modification to get around 'when I shift my arrow keys (to adjust the
cropping rectangle), my keyboard generates numbers instead' problem
(Mark Horstman (mh2620@sarek.sbc.com)
Modification to allow 'xsetroot' and 'xloadimage' to cleanup any
xv-displayed images in the root window, and vice-versa.
(Richard Bingle (bingle@cs.purdue.edu))
Rev: 11/26/90 (version 1, patchlevel 2)

(see the '-bfc' option)
fixed core dump when cropping on certain displays
misc. #ifdefs for HPs
fixed problem with fish cursor remaining around too long
more SVR4 #ifdefs (David Elliott, dce@smsc.sony.com)

Added POSIX signal handling (Mike Patnode (mikep@sco.com))
Port to SCO UNIX/ODT (Mike Patnode (mikep@sco.com))
fixed problem with using '-max' and '-fixed' at same time
(Greg Spencer greg@longs.lance.colostate.edu)
modification to work with Virtual Root Windows (ala swm and tvtwm)
(Bill Kucharski kucharsk@solbourne.com)
the 'save-as' filename is now set to the 'current' filename
Also, if you double click on 'plain' files in the directory box,
it will set the 'save-as' filename accordingly.
Added ability to view images centered on the root window, without
any tiling. Added associated options ('-center', '-rfg', '-rbg',
and '-rpat')
Workaround for twm 'No title bars' bug
(Steve Swales steve@bat.lle.rochester.edu)
Bidirectional Rotate commands added
Maxpect command added: (Maximum size, but preserve aspect ratio)
AutoCrop command added: (Crops out solid borders.)
Potential support for 32-bit displays. (Hasn't been tested. Don't have one.)
