I got it. Since you mentioned that the ImageJ Plugin uses environment variables, I took a closer look and realized that EPICS_CA_MAX_ARRAY_BYTES was not set in the terminal session I was running ImageJ from. Thanks for your help. - Yoram – From: Mark Rivers [mailto:[email protected]]
Hi Yoram, What version of areaDetector did you get the ImageJ plugin from? Starting with areaDetector R1-9 the ImageJ plugin gets the values of EPICS settings (EPICS_CA_MAX_ARRAY_BYTES, etc.) using environment variables, just like any channel access client that uses the C version of the CA client library. It
does not use the JCALibrary mechanism any more. This greatly simplified things for most people, since there is only one place that those settings need to be done for the IOC, C clients and ImageJ. This is documented in the areaDetector release notes for R1-9: http://cars9.uchicago.edu/software/epics/areaDetectorReleaseNotes.html However, I just noticed that I did not update the documentation for the ImageJ viewer to reflect this change, my apologies. I will do that this afternoon. Mark From: [email protected] [mailto:[email protected]]
On Behalf Of Yoram Fisher I am getting an error message that looks like: Feb 18, 2014 4:43:33 PM com.cosylab.epics.caj.impl.CATransport processRead SEVERE: Received payload size (2221056) is larger than configured maximum array size (16384), disconnecting... I am running EPICS base 3.14.12.3, areaDetector R1-9. ImageJ is running under Ubuntu . It is version 1.47v. The ImageJ plugin is EPICS AD Viewer. It is connecting to the PV correctly. The program creates an image window of the correct size, but the values are zero everywhere. 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.
I have taken a look at the documentation here: http://cars9.uchicago.edu/software/epics/areaDetectorViewers.html But could not get anything to work by making changes to the jre/lib/JCALLibrary.properties file. Any suggestions? Thank-you, - Yoram – Yoram Fisher Senior Systems Engineer Sydor Instruments, LLC 291 Millstead Way Rochester, New York 14624 Ph: +1.585.278.1168, Fax: +1.585.278.1169 Email:
