Image calibration is partially lost when using ij.ImagePlus input

[imagejan]

The image calibration for the Time axis is lost when using an input ij.ImagePlus in an IJ2 command via the ImageJ2 integration.

This small plugin illustrates this:
https://github.com/fmi-faim/fmi-ij2-plugins/blob/imageplus-calibration/src/main/java/ch/fmi/ImageCalibrationCheck.java

When using an input image with calibration (x=0.092, y=0.092, Time=0.05), the time calibration is only transferred when using a net.imagej.ImgPlus input.

Probably a bug in imagej-legacy, no?

I guess it's a bug somewhere here: https://github.com/knime-ip/knip-imagej2/blob/master/org.knime.knip.imagej2.core/src/org/knime/knip/imagej2/core/util/ImgToIJ.java#L228.
thanks for reporting!

Would be great to get rid of those IJ1<->IJ2 conversion classes in favor of using ImageJ Legacy. Let's discuss at the hackathon?

[dietzc]

absolutely. most of this stuff is very, very old.

What about the progress on this? Does it make sense to change this to use ImageJ Legacy? Or will it be moot with KNIP2 being released soon ;-) ?
