Yes.  Look at the fields of the XImage structure; they collectively
describe how the image is laid out in memory.

It does, actually, since that's the way Images work.

This is one of the weaker areas of X, mostly due to poor/nonexistent
documentation, which I suspect derives in part from incomplete design
work.

What you might want to do is teach your code about a few of the
commonest image formats, then use XPutPixel and XGetPixel for
everything else.  (First, though, make sure that XPutPixel/XGetPixel
are in fact too slow for normal use: make sure you need to do the work
before doing it!  getbdf, for example, does just fine with XGetPixel.)
I'd suggest starting with 8-bit and 1-bit formats, doing perhaps 4-bit
and 24-bit next....

As for determining the parameters, those are all members of the XImage
structure.  This structure is described in section 6.7 in the R4 Xlib
document, though figuring out precisely what each field means is an
exercise in educated guessing, preferably done with the protocol spec
at hand, as well as some experience in how images tend to be stored.

Hello net,

we're looking for a program to do stack a trace before it coredumps. We
would like to see, for example, the sequences of calls that resulted
in the program to bomb. 

many years back, we wrote something like this for VMS, using PL/1 and
it proved invaluable in helping us debug highly complex software. When
the program would bomb, we'd get a stack trace like:

Main:
   foo( )
     bar( )
        abnormal termination line so and so.

Now we're doing lots of X windows stuff and once in a while we dump
core and would like some hint as to why this happens.  This should not be
impossible as 'trace' does more or less what we want. We have our own
signal catcher (signal 11, where are you?) and at least do some damage
repair there but would very much like more information.

So it looks like I'm after 'trace' that can be linked in user programs
and provide us with the information above. Environment's strictly Unix,
SunOS and HP-UX.

Any hints on how to do this would be vastly appreciated...

Thanks in advance,

Spiros

   The first part simply isn't true.  Microsoft had "late beta" (read:
   "early alpha!") versions of NT running on 586 and r4000 boxen at the
   "Software Development '92 Spring" conference in Santa Clara.

   It looks like a somewhat-upgraded Win3.  It also brings the poor
   hardware to its knees.  (The r4000 in particular should really FLY.
   It doesn't.)


   Still, you're right --- it isn't even remotely objective to speak of
   Windows NT displacing Unix yet.  Not only beasts of different colors, so
   to speak, but of different habitat and development as well.

If you have a good quality photocopier you can photocopy optical mouse
pads and use that. Someone recently posted a postscript program for
producing optical mouse pads. Some of them will work on well-worn
denims.

Not an opinion one way or the other, but I've always found that
amusing (and useful if you find yourself short one mousepad.)

If the virtual root was created with the relevant backing pixmap

There isn't enough bandwidth for anything like normal performance, but it 
can be done.  We have run X over 9600 baud lines (via a stat mux, yet!).

A better answer would be to use XRemote - an x protocol designed 
specially for low-bandwith serial connections.  XRemote was written by 
NCD for their X terminals, but they donated a version to the Consortium, 
so it should appear RSN.  It is available now for pay from NCD.

     I'm  not  aware  of  a  vt100  doing  a  screen-clear when it get a
form-feed??!  I *am* aware that a Prime PT200 terminal goes to HOME (ie.
0,0)  when  it gets a form-feed.  All vt100 emulators I have seen either
ignore form-feed or throw a blank line instead (in fact, I find it quite
amusing that this comes form Computervision as I asked Prime whether the
PT200 could be configurable to ignore form-feed arther than going  home,
so that it looked more like a vt100....)

     Why  don't  you  get your software to send Esc[HEsc[J, which should
clear the screen for anything remotely close to a vt100.

Sunview has a nice feature that lets you store the position,

Hi Folks,

Two Questions...

1) Is there a bug in the HP X server that comes with a 700 series box. Sorry
   I don't know the server version ID.

   The bug is that if a make a pixmap, clear it using XFillRectangel,
   draw a string with XDrawString in the pixmap. The copy the pixmap, rotating
   it, into another pixmap, then copy this into a window, I get garbage where
   there should be a pixel rotated string. This is running on SPARC or
   DECstation and displaying on HP. It runs fine on all other platforms, when
   displaying on DEC, SPARC, IBM...

2) XtDefaultFont defines a backup font. I guess this is hard coded in the
   program and is not picked up at Program Invocation time. TRUE or FALSE?

   Evidence I have points to TRUE (unfortunately). ie if I run on a DECstation,
   but display on HP or IBM some fonts are found and in that case I ask for
   XtDefaultFont... that isn't found either!

Replies by email please and I'll sumarise, but use the NET if you need to.

Thanks people!

Like so many others, I'm interested in getting X up and running over a
modem.  I've read the FAQ and decided that XRemote looks like a
promising possibility.  (FAQ claims SLIP is to slow, PPP is not here
yet.)  I've found a Sun4 executable for XRemote using archie, and I've
read the 2 PostScript files that are essentially sales pitches (or
maybe a handwaving talk given at some conference).  I've seen (and used
on occasion) the NCD terminals that use XRemote and I know that 9600bps
is not all that great, but I'd like to try it anyway.  Just for fun I
started up XRemote from the console of a Sun4 and it spat jibberish at
me, just as I'd expect, probably initializing some protocol negotiation.

My setup: I have X running at home (under Linux) and a 9600bps modem.
I have the XRemote executable on a Sun4 at work.

Question: I would like to have xterms and other clients on the Sun4 at
work open windows on my server at home.  Is this possible?  I have not
heard of a program to do this.  I presume it would have to be a client
on the local end, at home, that talked to the modem, decoded the stuff
coming from XRemote at the other end, and manipulated the display
accordingly.  It sounds like quite a large task and I'm wondering if
anyone has ever heard of such a beast.  Has NCD ever released the
protocol used by XRemote?  Even better have they ever released the
source code their terminals use?

Please respond via e-mail and I'll post a summary.  It may even
be worth putting in the FAQ.
