Wayne,
thanks, the thing is I have a separate class cal, it's a class I wrote myself.
This class implements the getCalibration functions which returns a Calibration
object, in which I filled w,h and the unit.
So I can imagine that you can't compile it. I did show this on the last
developer conference, maybe you remember it.
This class detects a blue area in the image and decodes the qrcode within this
area and does a calibration based on a black disk with holes.
The number of holes determines the size of the disk. I'm currently making a
separate plugin for this calibration and decode.
The idea is that the plugin gives a new image with only the blue area, the
decoded qrcode as title and calibrated according to the disk.
This way this information can be used in other plugins. I don't see other ways
to get this information from the plugin.
Or I need to return a resultstable which is little bit of overkill in my
opinion.
I don't see why IJ.log("1-> "+cal.getCalibration() + " - " +
cal.getCalibration().scaled()); works,
and overlay_im.setCalibration(cal.getCalibration()); not.
Even more since it worked properly last week ????
The only thing which was changed is the Fiji update this morning, I believe
ij1.47h to 1.47i, along with other libraries.
In the mean time I found another problem, I have implemented the
run(ImageProcessor ip) in my plugin.
I do a ip.setroi(roi of blue region) at the end and after running the plugin
this roi was set on the input image.
It is very handy to have this information for further processing of the input
image.
This behavior also stopped working this morning, the roi now is set to the
whole image.
Is there a way to downgrade Fiji, in order to test this with 1.47h?
is Barry DeZonia right, does this question better fit on the regular list?
I'm a little bit confused,
thanks,
Gerrit.
