Re: ImageJ Plugin not working with Area Detector

["Kasemir, Kay" <kasemirk@ornl.gov>]

There are several ways to pass those settings.

One is like this:

CA_SETTINGS="-Dcom.cosylab.epics.caj.CAJContext.addr_list=192.168.62.255 -Dcom.cosylab.epics.caj.CAJContext.auto_addr_list=false -Dcom.cosylab.epics.caj.CAJContext.max_array_bytes=100000000"
java -Xmx512m $CA_SETTINGS -jar $EPICS_EXTENSIONS/src/ImageJ/ij.jar

That way, you know for sure what's passed without having to hope that you edited the correct JCALibrary.properties.
Also note that the max array size needs to be set on both the IOC and the client.
I've been running into the case where the client complained, but the limit was actually too low on the IOC side.

If I use the “FileTIFF1” plugin I can save tiff images, and they are correct.  I have the “Image1” plugin enabled.  I am using the SimDetector IOC on the same Ubuntu machine.
