I assume, from this description, that imgworks is
unintentionally flipping the image upside down?

The SGI file format assumes the lower-left corner
of the image is the origin, while TIFF, being a more complex
file format, allows you to specify the corner of origin.
Most applications deal with an upper-left origin, though
imgworks is supposed to be smart enough to do the right
thing and not invert the image.  If it isn't, it's a
bug.

A workaround for this problem is to flip the image yourself
before saving, so it will land in the file right side up.
See the "Flip Vertical" command on the Effects menu.

Probably, but it is unlikely to be fixed anytime soon.

Speaking as the author of imgworks, I'm not very pleased
with the "type-a-number-in-the-box" approach to the Crop
feature, either.  Given more time and a different set of
circumstances, something better would have emerged.  My
only defense is that the feature works as advertised...

I've since moved on to other projects, so I can't say
with certainty what the future plans are for upgrades
or replacements for imgworks and the rest of the image
tools.  I do know that the ImageVision group is very
interested in providing a set of image manipulation tools
which provide a better set of features than the current
ImageVision Tools, so I would be optimistic about the
future.

Subject: Is there a journal?
Organization: U.S. Naval Research Lab, Washington, D.C.
Date: Tue, 22 Dec 1992 18:29:14 GMT

In IRIX 3.X there was a journal program that would record all mouse, keyboard,
etc. events and save them in a file.  The script could then be replayed later.
I was wondering if there is such a program written for 4.X.  I want to make a
demo of a program, and I want to have the mouse movements (i.e. selecting
choices from pull-down menus) scripted.  I don't want to hard-code anything, 
because I will probably be making many different demos.  I would appreciate
any help you could give with this.  Thanks.

Subject: SCSI printers
Date: 21 Dec 92 10:54:45 GMT


Does anyone have experience with connecting a ps printer to SGI
boxes via the SCSI {1,2} bus ?

I have a zippy Xante ps printer. It is quite fast, and I have
it connected via a centronics port. I have a breakout box on the
line, and I see lots of handshake activity. I think that the
printer is out pacing the parallel port on large bitmap images.
The printer ready line is can be trapped with no data on the data lines.

This wonderprinter has a SCSI port, and is designed for direct connection
to Apple machines. 

Any insight about connecting this to a IRIS ? 

What is the max throughput on the parallel lines ?
What is the bottleneck in getting data out a parallel line ?
The CPU wait line shows lots of physical io waiting, like the
whole CPU wait bar is light blue (whatever that means!).

What is the throughput on the SCSI 1 or SCSI2 bus ? What are the
bottlenecks there ?

Would it pay to write/debug a SCSI driver for this beast ? Is there 
lp scripts that talk/listen to the SCSI port ? What are the
issues to connect a program to a SCSI port ? Kernel drivers ?
I don't know if the printer will try to converse with the host
via the SCSI port.

Cheers!

Dan.

Date: Thu, 24 Dec 1992 16:48:14 GMT

When I load eoe2.sw.demos in IRIX 4.0.5, I notice a few differences.

Loaded to an Indigo, GTX, VGX, the following files for "flight" exist:

l---------   1 root     sys           21 Sep 17 13:47 dog@ -> /usr/demos/bin/fli
-rwxr-xr-x   1 demos    demos     299184 Sep 17 13:47 flight*
-rwxr-xr-x   1 demos    demos     405680 Sep 17 13:47 flight_8bit*
l---------   1 root     sys           21 Sep 17 13:47 shadow@ -> /usr/demos/bin/

On a Personal IRIX 4D/35 (all three I loaded it to) only the following appears:
-rwxr-xr-x   1 demos    demos     405680 Sep 17 13:47 flight_8bit*

Is flight not supported on the PI?

If so, are there other demos besides "flight" that are not loaded by 4.0.5
on the PI?

Here is output from hinv on the PI.

The problem with moving drives to the Mac is that many models

properly on power up or after SCSI bus reset.

Conversely, many drives for the Mac have rather poor SCSI implementations.
The Quantum drive will probably work, but there are no guarantees.

Yes, 7 ;)  (only 7 non-host SCSI ID's, for those who don't know
SCSI).

Check that you have the last device terminated, and no others,
also check that aren't trying to use the same ID as one of
the internal devices (hinv output helps).

Make sure you have good external cables, not the parallel port
printer cables that happen to look similar (and aren't!).

In the case of disks, this is almost always a SCSI bus error of some
sort (bad cable, loose connector, missing or extra terminators), since
they almost always disconnect on a block boundary.

SGI's DMA hardware requires word (low 2 bits of address 0) aligned
addresses to work; this message tells you that the disconnect was
not on a word boundary.  The 0 left part is a bug in my code; it *always*
prints 0 in some releases; I think I fixed it for 405, but it might
have been 405F.

What sort of throughput are you looking for? I'm currently using an
IRIS 4D/35G for real-time acquisition and processing (soon to move to
an Indigo R4000/XS24Z), with rates of about 200 kpoints/sec. I use three

You need to bug Ardat or your distributor for newer firmware.
Almost certainly this is not a drive purchased from SGI.  I
asked Ardat to put the fix into their standard firmware, since
SGI isn't the only system with problems on non-word aligned
DMA (which is what happens when the drive disconnects on
a boundary not a multiple of 4 bytes from start of transfer).

They said they would do put it in their next general firmware
release, but either that hasn't happened, or you have
older firmware.

There is no workaround except to disable SCSI disconnects,
which has problems of its own (see master.d/scsi).

ndirect extents

in SYSLOG. Is this just a sign of the disk going bad (I admit it's no SGI disk,
but has workes flawlessly for at least 3 years now) or did we
inadvertently make some configuration or software error ?

Thanks very much for any hints,

This message indicates that the device did not disconnect on a 32-bit
word boundary.  The device itself may allow this to be configured; I
believe our SCSI drivers require this.
