Re: areaDetector and ADRoper; view files in imageJ

Dear Mark,

Thanks. It was my fault because a typo in this environment variable.
The funny thing now is that imageJ opens a white canvas. As soon as I 
open the brightness dialogue the image is how fine.

Thanks.

In your screen shots the images are 1024x1024 16-bit.  That means EPICS_CA_MAX_ARRAY_BYTES needs to be at least 2MB=20897152.  I would recommend setting it to 10000000 in case you use some larger cameras as well.
