Sequencer->Format-ReadImage
Sequencer will output integers, which can correspond to your file sequence
numbers and give you a VCR like-widget.  Pass the output to Format, which
is like a sprintf in c.  You can use it to compose your filenames (e.g.,
"my_image%0d.jpg" for my_image01.jpg, my_image02.jpg, ...).  ReadImage
originally only supported raw rgb, TIFF, GIF, MIFF.  I don't know off-hand
if the ImageMagick extensions for output also are supported for input so
that IM convert is invoked to read JPEGs.

Inside a network, you can do a ForEach loop reading each image and
appending it to a series group, whose member value corresponds to a
position in Z.  After the loop is completed, then do a Stack on the series
group and it will create a volume.  The Accumulate network in the sample
set shows one way of doing a loop.  The couple of samples entitled MRI,
show some ways to look at such a volume.

Subject:  [opendx-users] Programs to get Jpeg slices into volume?



Hello, all:              7/31/2000
I have two questions:
1) how to automatically read in image files (jpeg slices) with sequential
file numbers
    without typing in the file names every time? Any examples that you
know?
2) Is there a net program that can merge these slices into a volume data
set
for
   rendering?
   (The dxsample example which uses STACK module does not tell very much.)
Thanks for your help.
