The Library should definitely be "device-decomposed-independent",
but I can believe things look silly on any but a 24-bit graphics
card. Dave and I both thought there was no sense any more writing
software that is restricted to 8-bits of color. It is a lot of work
for machines that *surely* are going to be obsolete real soon now. :-)

As soon as I get a customer that requires DICOM output, I'll
probably have to purchase that option. Meanwhile, my second
son is picking out colleges and my attention (and wallet) is
directed elsewhere. :-(

What is PACS, anyway? Never heard of it.

Cheers,

David

Wonderful! Works in idl 6.1 on SunOS 5.9. The images occasionally look a

I wouldn't mind seeing 'Save window as DICOM' or perhaps even 'Send

DICOM Toolkit (DCMTK) for a while now. Amongst many other things DCMTK
allows you to send/recieve images using command line executables. I've
also got a DICOM writer which is just a logical extention of
dicom_writer.pro.

Thanks David,

David,

I am definately on 24-bit graphics display. If I do the following commands:

a = dist(255) & b = rot(a,33) & c = rot(a,60)

erase & tv, a, 0,0, 1 & tv, b, 0, 0, 2 & tv, c, 0, 0, 3

It looks as it would in windows.

My idl startup tells all:

adac9{24}(~/idl) > more idl.startup

device, TRUE_COLOR=24
device, decomposed=0
!order=1

I'm guessing that your application picks up that I'm using decomposed=0
and takes the sensible precaution of never trying to display more than
256 colors.

I think I used device, decomposed=0 because some of our older
workstations here use Pseudo color. I too am of the opinion that they
are ready for the junk heap.
