Re: Point Grey Flea3 areaDetector ImageJ Viewer Problems

Matt,

Thank you for the response.  EPICS_CA_MAX_ARRAY_BYTES is set to 100000000, which should be plenty for a single image at 1280x1024.

Perhaps EPICS_CA_MAX_ARRAY_BYTES is not set large enough ?

From more testing:

A camonitor on PG1:image1:ArrayData shows that the values in the array are changing as the camera is moved around, so the array is getting updated.

ImageJ still shows a zero-value array.  The image shown from the plugin is 1280x1024 (8-bit) as it should be, but no pixel values.

The Array Counter in for the StdArray increases with the image count, but I did notice that the Unique ID for each array does not change (not sure if this is relevent, have not paid attention to this parameter before).

Hello,

I am using the new Point Grey pre-built in windows 7 x64.  I am having issues streaming the images to the ImageJ areaDetector plugin.

I am able to acquire images in all image modes (single, multiple, continuous) and save the images using the TIFF plugin, but the NDStdArrays plugin does not seem to be getting any data, so the callbacks do not update, so the ImageJ plugin does not stream.

PG1:cam1:ArrayCallbacks is set to Enable
PG1:image1:EnableCallbacks is set to Enable

If any more information would be helpful, please contact me, thank you,
