Dear friends,
I have been a happy user of the Mac OS 9 versions of Scion's ImageJ
plugins for their digitizing boards (we have more than one AG-5),
which I have adapted for my own 4d acquisition suite. I'm now trying
to get the plugins working under Mac OS X 10.4 (Tiger), under Java VM
1.4.2. I have tried my modified plugins, Scion's plugins bundled with
the old ImageJ 1.23, and their newer plugins under ImageJ 1.34 for
use with their newer FG7 board. They all throw exceptions related to
the creation and/or conversion of Simages (a Scion data format) to
ImageJ ImagePlus objects. This means that the "Capture Grayscale"
plugin fails at this point, and the "Export" option within the Live
Capture plugin fails with a general exception. The plugins compile,
but there seems to be something wacky at this point.
I've provided the ImageJ exception and the console error,
respectively, below. Note that I can see a live image using the Live
Capture plugin, I can adjust the board's settings, save these
options, and toggle visibility of the toolbar and status bar. Adrian
Daerr's JNIAkiz plugin works, but because it doesn't provide the
ability to modify the gain and contrast settings and averaging
settings, it are not optimal. Moreover, the Scion plugins do exactly
what I'd like under OS 9.
Thanks in advance for your help!
Cheers,
Jeff
