I've written a macro that uses the Layers plugin
(
http://www.optinav.com/Layers.htm) to turn an image stack into a single
image, the generated composite image is then saved to disk by the macro.
The macro works flawlessly when I run it by starting ImageJ from a
terminal command line using the -macro switch to reference the macro
script. Now that it is working I want to incorporate it into a cgi
script to be called by a web server, using exactly the same settings as
used in the command line. But when I start things from the cgi script,
the generated composite image is blank and the resulting saved file is
empty. I can see ImageJ starting and loading the image stack as
expected, but the composite image window when the plugin creates it is
always blank.
My machine is a Mac Pro running Snow Leopard, and I'm using ImageJ
1.45k. If it were Unix I would check the X Server related environment
variables set in my cgi script. But I'm not so familiar with the Mac's
visual systems. Knowing what little I know I can't imagine why it
should make a difference that I'm calling the macro from a script as
opposed to a terminal window. Is there some OS configuration value or
environment variable that I should have set in my cgi script before
calling ImageJ?
Any hints would be appreciated.
Thanks,
