I've fixed this for Windows machines, but I suspect this is one
of those things that needs to be tweaked for each OS. If you want
to tell me what the numbers are on *your* machine, I can cobble
something together. Go to lines 237 to 248. My fudge numbers are
95 and 8. Let me know what yours need to be to make this resize
correctly for you.
> The information bar update is reeeeeealy slow with color images
I've changed the algorithm that calculates the image value. I tried
it with a [3, 2270, 1490] image array, and it is slick as snot on
my (aging) machine. I'd be curious to see how it performs on your
machine.
> Sometimes a drag-resize results in multiple resize events *flash*

If I saw this on my Windows machine, I would assume the "Show Window
Contents on Drag" button was on. I would right-click on my desktop,
go to Properties -> Appearance -> Effects and turn it off. I don't
know anything about the Macs, but I presume there is something
similar. It can be *most* annoying on Windows machines!
> How can I see the image at full resolution?
Set the FULL_RESOLUTION keyword when you start the program.
No charge. :-)

This reminds me of some advice I was given: Programming is a statement
of intent to the computer. If you're stating something *other* then
the task you want to complete, then there is something wrong.
My problem is that I frequently find myself in a situation where I
need to solve problem A to solve problem B. For example today I just
found that SAVE can't handle COM references anywhere in the object
heap which is being serialised. So now I have to proxy all COM objects
to a hidden place where SAVE can't get to them (I used a common
block).
I really thankful that having someone else understand my code is a
secondary priority.
Thanks for the tip,
Robbie

Oh, it's an idea generator, all right! Ask ITTVIS, if you
don't believe me, but the main problem with objects is that
you think of so *many* neat ideas that if you are not *extremely*
careful the complexity just gets completely out of hand.
The idea, it seems to me, is to be boring, boring, boring
as a programmer. Restrict yourself to one great idea a day. That
way, you see steady progress, but the programs don't become so
hopeless you throw up your hands in exasperation. You can see
the consequence of having too many great ideas if you look at
the code for any of the iTools. :-)

David

I really wish I had have bought the Catalyst library. At the very
least, it would have given me ideas on how to churn out at least half
useful applications. It's great that you are making it open source. It
seems very difficult to be able to *sell* any piece of library
software nowadays. The most common strategy seems to be to give it
away for free (open source or not) and then charge large amounts for a
value-added service or feature.
Maybe if people like me had have bought it then you would have been
able to afford a mac?
I'm looking forward to see if coyote is willing to take an adventure
to Java.

OK, at least the obvious bugs are fixed. It is still not perfect,
but I'm content to wave my hands at the rest of the darn things for
the time being. I *really* have better things to do today.
I haven't yet tried this with massive images, but I do know
the part of the code that selects the image value was written
in 2003 and I do things *much* differently with the combination
of TVImage and TVInfo (similar functionality). So it is possible
I can speed up that algorithm considerably. I just don't have
time to work on it anymore today, though.
The part that concerns me the most is the "flashing" while
dragging complaint. I've had reported problems with this on Macs,
but haven't been able to snag a Mac yet to see what the problem
might be. My youngest is going on a road trip next week. Maybe
I'll see if he can drop off his Mac before he leaves. I'm guessing
I'll have to delete about 10000 movies to get that IDL workbench
installed. :-(

OK, so 30" isn't big enough. Hey, Apple, could you make a 60" monitor?

David,
it works like a charm!
I have only been playing with it for 5 minutes, but I already love it!
Ciao,

This is definitely broken. And I don't immediately see
why. But it is using XSTRETCH, a pretty reliable routine,
so that must be broken, too. I have my Gonzales and Woods
out and I'm looking into it.

Whoa! That *definitely* didn't happen the last time I looked
at this, but it *is* happening now. Weird. I tried to finesse
a 2003 programming style into a 2008 program. I may have to go
back and do this the right way. :-(

Well, it doesn't on my machine, but it may on yours. What is yours?

How big is your image? I haven't seen slow at all, but maybe
I'm using images that are too small.
> How can I see the image at full resolution?
Bigger monitor?
My plan is to get someone excited about developing with this
system and to get them started on making this little application
into an ENVI-like thing with a full-size image, a zoom window, and
a full-resolution image. But, alas, I have a job now. :-(
Thanks for the feedback. I'll see what I can do.
Cheers,
David

Whoa, buggy!!!
Linear 2% is broken -- everything is black
'Load Color Table' widget moves around if you select the Brewer/IDL
colors button
If you select the 'maximize window' button, the information bar at the
bottom disappears
The information bar update is reeeeeealy slow with color images
Sometimes a drag-resize results in multiple resize events *flash*
*flash* *flash*
How can I see the image at full resolution?
